SMARC-sAMX7 User Guide. Rev. 1.5

1/ Introduction

This manual describes the Smart Mobility ARChitecture (SMARC) sAMX7 (SMX7) board. The Advanced RISC Machines (ARM) based module is equipped with a NXP i.MX7 processor. The single or dual core SoC take advantage of the optimized power consumption and performance ratio.

The use of this Users Guide implies a basic knowledge of PC hard- and software. This manual is focussed on describing the special features and is not intended to be a standard PC textbook. New users are recommended to study the short installation procedure stated in the following chapter before switching on the power.

All configuration and setup of the CPU board is either done automatically or manually by the user via the BIOS setup menus.

Latest revision of this manual, datasheet, BIOS, drivers and BSP’s (Board Support Packages) can be downloaded from Kontron Web Page.

SMARC-sAMX7 User Guide. Rev. 1.5

2/ Description

The SMARC-sAMX7 is a SMARC half-size module using the NXPs i.MX7 processor with either single or dual core ARM. It is designed on the latest SMARC 2.0 specification and supports ARM or x86 architectures. The SMARCsAMX7 is a highly integrated, embedded computer board.

Figure 1: Half-size Card with SMARC interface

2.1. SMARC™ Computer-on-Modules

The SMARC™ standard was developed especially for new modules with ARM- and SoC-processors. Boards with this interfaces are characterized by the extremely flat form factor. The SMARC or MXM 3.0 connector comes with 314 pins and a construction height of just 4.3 millimeters. The connector is also available in a shock- and vibrationresistant version for rough environmental conditions.

Furthermore, the standard integrates dedicated interfaces for the latest ARM, x86 and SoC processors like LVDS, 24-bit RGB and HDMI support. In addition, dedicated camera interfaces are being incorporated into a COM standard. OEMs profit from minimized design effort and low Bill of Material (BoM) costs. SMARC™ defines two different module sizes in order to offer a high level of flexibility regarding different mechanical requirements.

No

From U-Boot

U-Boot only supports booting from QSPI NOR flash because "boot from fuses" is defined per default.

6.2. Configurable Watchdog

As no CPLD is available, the Watchdog must be used from the SoC. The WDOG features are listed below:

 Configurable timeout counter with timeout periods from 0.5 to 128 seconds which, after timeout expiration,

result in the assertion of WDOG_RESET_B_DEB reset signal .

 Time resolution of 0.5 seconds  Configurable timeout counter that can be programmed to run or stop during low-power modes  Programmable interrupt generation prior to timeout  The duration between interrupt and timeout events can be programmed from 0 to 127.5 seconds in steps of

0.5 seconds.

6.3. RTC current consumption

The current consumption of the sAMX7 was tested with following circuit. Jumper was populated to J58 position 1-2. With an external power supply J37 was feed with voltages from 2.0 V to 3.4 V.

Figure 8: RTC current consumption with an external power supply and voltages from 2.0 V to 3.4 V

The module RTC (RV-8803) can operate down to 1.5V, the i.MX7 RTC minimum supply voltage is 2.4V.

Table 11: Minimum Supply Voltage of the RTC Module

Ambient temperature

-20°C

25°C

85°C

Because of the high voltage drop of the BAV99 diode on the SMARC Eval-Carrier 2.0, only the module RTC (RV-8803) will keep the time on cold ambient temperatures.

Therefore for using i.MX7 RTC also – this is not recommended, because the accuracy is worse than RV8803 – BAV99 should be replaced with a suitable Schottky diode which has lower voltage drop.

Because the sAMX7 module has a reverse serial protection in the VDD_RTC signal with a diode, no super cap charging from module side is possible without shorting the diode on the module.

NXP has defined the UART handshake lines in the opposite way from many other vendors. In the SMARC 2.0 specification RTS is defined as an output and CTS as an input. This is the same definition used by the standard PC serial port.

However, in the iMX7 implementation RTS is an input and CTS is an output – i.e. the pin functions corresponding to these names are swapped.

Per table 17 below, configuring the UART for DTE mode will result in the signals being routed to the SMARC pins in conformance with the SMARC definition of the pin functions.

The DTE mode is designated for the SMARC-sAMX7 module. Following additional UART interfaces can be optionally used:

 UART1 shares I2C1 at i.MX7 and I2C_LCD pins at SMARC 2.0 connector. They are only useable if display

converter (SN65DSI84ZQER) is not placed.

 UART2 shares SPI[4]_Master Input, Slave Output/Master Output, Slave Input (MISO/MOSI) at i.MX7 and

GPIO7/GPIO8 pins at SMARC 2.0 connector. They are only useable if APPROTECT key does not use SPI option with additional resistors and omit SPI level shifter TXB0104RUT.

 UART3 shares 2x GPIOs at i.MX7 and GPIO9/GPIO10 pins at SMARC 2.0 connector.

Pressing the power button for at least 4 seconds will turn off power to the module (Power Button Override).

6.5. Power Control

6.5.1. Power Supply

The SMARC-sAMX7 supports a power input from 3.0 to 5.25V. The supply voltage is applied through the VCC pins (VCC) of the module connector. Considered current rating of protective device is part of End-Equipment.

The following parameters should be delivered from the carrier board:

 Voltage Ripple maximum 100 mV peak to peak 0-20 MHz to 20 ms rise time from

input voltage <10% to nominal VCC

 Max allowed inrush current: connector limit (15 W @ 3,0 V)

6.5.2. Power Button (POWER_BTN#)

The power button (Pin P128) is available through the module connector described in the pinout list. To start the module via Power Button the PWRBTN# signal must be at least 50 ms (50 ms ≤ t < 4 s, typical 400 ms) at low level (Power Button Event).

6.5.3. Power Bad Signal (VIN_POWER_BAD#)

The SMARC-sAMX7 provides an external input for a Carrier Board Power Bad signal (Pin S150). The implementation of this subsystem complies with the SMARC Specification. VIN_POWER_BAD# is internally pulled up to 3.3V and must be high level to power on the module.

6.5.4. Reset Button (RESET_IN#)

The reset button (Pin P127) is available through the module connector described in the pinout list. The module will stay in reset as long as RESET_IN# is grounded.

U-Boot is free Software. It is copyrighted by Wolfgang Denk and many others who contributed code. U-Boot can be redistributed and modified under the terms of version 2 of the GNU General Public (GPL V2) License as published by the Free Software Foundation.

Actual source code of mainline U-Boot and authors of the source can be obtained from the git repository at

 git://git.denx.de/u-boot.git

SMARC-sAMX7 bootloader sources are derived work from a dedicated version of mainline U-Boot, e.g v2017.03. As bootloader evolves, the root of the derived work might change to a later version.

The source code of U-Boot will be delivered with the standard software package. Additionally the software can be downloaded from Kontron GitHub repository for SMARCsAMX7: https://github.com/kontron/u-boot-smarc-samx7

7.2. Bootloader Quickstart

The SMARC-sAMX7 board comes with U-Boot preinstalled on the QSPI flash device. Follow the steps below to gain access to the bootloader command line (CLI) on your host PC.

 Connect your host machine to the carrier port connected with the edge connector SER0 port of the module.

On Kontron SMARC 2.0 carrier this port is named SER_0.

 Start a suitable terminal program on your host and attach it to the port connected with the board’s serial

interface. Configure the serial line using

 Connect power supply to the carrier and power up.  When boot messages appear, press any key to stop automatic boot sequence.

After power on, bootloader boot messages will appear as shown below. There is a 3 second boot delay counter that will try to boot linux OS automatically after expiration. Pressing any key will stop the boot delay counter and enter the bootloader CLI

7.3. Bootloader Commands

The bootloader CLI provides a bunch of powerful commands to control the board, which basically can be grouped into

 Information Commands  Memory Commands  Flash Memory Commands  Execution Control Commands  Download Commands  Environment Control Commands  Flattened Device Tree Support Commands  Storage Device Control Commands  File System Support Commands  Kontron Command Extensions

Typing “help” at the bootloader command line prompt will show up a list of the commands available. Typing “help <command>” will show specific command help. Further help can be

On the SMARC_sAMX7 bootloader, the powerful hush shell is enabled, which is similar to Bourne shell and provides features similar to a linux shell:

 Control structures (if … then … else … fi etc.)  Command line completion  Command line editing  Command line history up to 20 entries  Local environment variables

7.4. Kontron Bootloader Command Extensions

Kontron’s implementation of U-Boot includes certain enhancements to provide board specific functions. They are not part of standard U-Boot as maintained by DENX. The following table provides a complete listing of all Kontron command extensions on the SMARC-sAMX7.

Table 17: Bootloader Command Extensions

Command Description

kboardinfo Kontron Board Information - Displays a summary of board and

configuration information

md5sum Creates or checks the md5 message digest over a memory area

watchdog Start and control i.MX7 CPU watchdog

7.4.1. kboardinfo - Kontron Board Information

The "kboardinfo" command shows a summary of board serialization data gathered from the system EEPROM.

7.4.2. md5sum – MD5 Message Digest

The "md5sum" command is already part of standard U-Boot implementation. However Kontron provides the "-a" extension (ASCII) that allows to check MD5 checksum of a given memory area (e.g. a binary image copied into memory) against the checksum that has been copied into an ASCII file on an external linux host. To achieve this, the ASCII string in the file representing the checksum is converted into hexadecimal values and compared against the calculated one.

=> help md5sum md5sum - compute MD5 message digest

Usage: md5sum address count [[*]sum]

- compute MD5 message digest [save to sum] md5sum -v address count [*]sum

- verify md5sum of memory area md5sum -a address count [*]sum

- verify md5sum given in ASCII format

Calculate MD5 checksum of a given binary using the md5sum command on linux host and redirect output messages into a file:

# md5sum image.bin >image.md5

Copy both image file and checksum file to USB thumb device with EXT2/3/4 or FAT partition. Connect the USB device to the module carrier.

The following sequence shows how to load both image file and image checksum file into SMARC_sAMX7 memory and compare them. In case of success, the "md5sum -a" command will have no output messages as this extensions is meant to be used in automatic update scripts to check the binary images against their MD5 checksum.

usb start load usb 0:1 88000000 <image.bin> load usb 0:1 8a000000 <image.md5> if md5sum -a 88000000 $ubootsz *88a00000; then echo ‘CRC check passed’ else echo ‘CRC check failed’ fi

7.4.3. Watchdog – CPU Watchdog Control

The "watchdog" command is used to control the i.MX7 CPU internal watchdog. After watchdog has been started using "watchdog start", the watchdog is kicked periodically by U-Boot to prevent expiration.

Watchdog timeout can be changed at any time. However, it is not possible to stop watchdog once it has been started.

www.kontron.com // 50

=> help watchdog watchdog - start/stop/kick IMX watchdog

Usage: watchdog <timeout> - kick watchdog and set timeout (0 = disable kicking)

SMARC-sAMX7 User Guide. Rev. 1.5

Example

watchdog start <timeout> - start watchdog and set timeout

Start watchdog with 5 seconds timeout and stop kicking watchdog some time later. Board will reset after watchdog has been expired.

:

=> watchdog 5 => watchdog 0

7.5. Bootloader Environment

The bootloader environment is used to control bootloader and OS startup behavior. Environment variables can be used to control boot timing (e.g. bootdelay), interface properties (e.g. baudrate, ethact) or they define memory locations where OS images are stored before boot (e.g. loadaddr, fdt_addr). In addition, bootloader shell commands can be combined to environment scripts.

The redundant bootloader environment is permanently stored in the QSPI flash device at offset 0x1C0000 and 0x1C8000. During bootloader operation, the environment is held in RAM memory and can be modified and written back to persistent storage.

Bootloader commands to modify the environment are summed up under the "env" command group:

 env default [-f] –a [forcibly] reset default environment  env default [-f] var [...] [forcibly] reset variable(s) to their default values  env delete [-f] var [...] [forcibly] delete variable(s)  env edit name edit environment variable  env exists name tests for existence of variable  env print [-a | name ...] print environment  env run var [...] run commands in an environment variable  env save save environment  env set [-f] name [arg ...]

However, the legacy commands for environment handling are still available:

 "setenv",  "editenv",  "printenv"  "saveenv".

U-Boot standard environment variables are set up for the SMARC_sAMX7 module as shown below

Table 18: Standard Environment Variables

Variable Value Description

baudrate 115200 Serial line baudrate

bootcmd Run mmcboot || run sdboot || run usbboot ||

run netboot || run bootfailed

bootdelay 3 Wait 3 seconds before executing bootcmd

ethprime FEC0 Use Ethernet port FEC0 as default

loadaddr 0x80800000 Default memory location for OS boot

A typical user modification would be to set the variable "bootcmd" to change OS boot commands.

Try booting (in this order) from eMMC, SD card, USB, network

the appropriate device tree file

SMARC edge connector is used as GPIO.

Variables from the table above marked in bold are set automatically each time U-Boot starts. They will override different settings possibly stored in persistent environment.

7.7. Bootloader Mass Storage Support

U-Boot provides support to read and write from mass storage devices like

 QSPI flash  eMMC device  SD card  USB thumb device

7.7.1. QSPI flash

QSPI flash is accessed using the "sf" command

Load one sector (64K) from SPI flash

=> sf probe 0 => sf read ${loadaddr} 0 10000

7.7.2. SD Card and eMMC Devices

eMMC and SD card are accessed using the "mmc" command

www.kontron.com // 52

Load 256 blocks from eMMC

=> mmc dev 1 => mmc read ${loadaddr} 0 100

Example:

7.7.3. USB Storage Device

USB storage devices are accessed using "usb" command

SMARC-sAMX7 User Guide. Rev. 1.5

Load bootloader update file from USB thumb device

=> usb start => usb dev 0 => fatload usb 0:1 update_smx7_spl/u-boot-smx7_spl.bin

7.8. Bootloader File System Support

U-Boot for the SMARC_sAMX7 provides support for FAT and EXT4 file systems. EXT4 support also includes EXT2 and EXT3 formatted file systems. There are file system specific commands available to list file system contents (ext2ls, fatls) and load a given file into board memory (ext2load, fatload). However, U-Boot also provides generic commands ("ls" and "load"), that will detect the file system on the device and use appropriate file system functions automatically.

Show /boot folder contents from SD card file system

=> ls mmc 0:1 /boot <DIR> 4096 . <DIR> 4096 .. <SYM> 48 imx7d-samx7-ld101-m4.dtb 44034 devicetree-zImage-imx7d-samx7-ld101-m4.dtb 43986 devicetree-zImage-imx7d-samx7-ld101.dtb <SYM> 33 zImage <SYM> 45 imx7d-samx7-ld101.dtb <SYM> 45 imx7s-samx7-ld101.dtb 6376512 zImage-4.1.29-fslc+g59b38c3 43998 devicetree-zImage-imx7s-samx7-ld101.dtb

=> load mmc 0:1 ${loadaddr} /boot/zImage 6376512 bytes read in 536 ms (11.3 MiB/s)

7.8.1. EXT4 File System Write Support

There is even support available to write a given memory area into ext4 formatted file systems. However, the implementation is not bullet proof und should be used with care, as this could lead to file system corruption.

Writing to symbolic links in an ext4 filesystem does not work from u-boot! Do not create new files in ext4 filesystem as this could cause problems.

7.9. Bootloader Network Support

U-Boot provides support for both onboard Ethernet interfaces. The current interface can be selected by setting "ethact" environment variable to either “FEC0” or “FEC1”.

Board specific MAC addresses are read from EEPROM during startup and environment variables are set automatically. In case EEPROM contents is missing or corrupted, a "random" MAC address will be set to "ethaddr"

In case that the current network interface is attached to a network providing a DHCP server, an IP address can be gathered using "bootp" ord "dhcp" commands.

After that, a file from a tftp server can be copied to memory using the "tftpboot" command.

=> bootp => tftpboot ${loadaddr} <filename>

www.kontron.com // 53

SMARC-sAMX7 User Guide. Rev. 1.5

7.10. Bootloader Boot Source Support

The SMARC v2.0 Specification defines three boot select signals BOOT_SEL[0:2]# that allows the user to select from eight possible boot devices. On the SMARC_sAMX7, U-Boot detects the BOOT_SEL signals from the carrier and sets the environment variable "boot_sel" as shown below.

Table 20: Environment Variables for "boot_sel"

BOOT_SEL2# BOOT_SEL1# BOOT_SEL0# boot_sel Boot Source

GND GND GND carrier_sata Carrier SATA

GND GND Float carrier_sd Carrier SD Card

GND Float GND carrier_mmc Carrier eSPI (CS0#)

GND Float Float carrier_spi Carrier SPI (CS0#)

Float GND GND module_device Module Device (NAND, NOR) – vendor

specific

Float GND Float remote Remote boot (GBE, serial) – vendor

specific

Float Float GND module_mmc Module eMMC Flash

Float Float Float module_spi Module SPI

Bootloader environment scripts can use the boot_sel environment variable to select the source where the dedicated OS image can be loaded. As an example, the bootloader environment of the SMARC_sAMX7 implements some small scripts that will load a linux system from the boot source as defined by the BOOT_SEL pins.

bootsel_boot=echo BOOT_SEL ${boot_sel} selected && run ${boot_sel}_boot module_mmc_boot=run mmcboot module_spi_boot=run mmcboot

Running the "run bootsel_boot" script will load a linux system from MMC if BOOT_SEL pins define the module MMC Flash or the Module SPI as boot source. Depending on application, the script variables in environment can be adapted.

The bootloader is always booted from the boot source defined by fuse settings, which is normally the QSPI flash device. The BOOT_SEL pins only define boot source for the OS.

7.11. Bootloader Boot Counter

The module EEPROM device contents implements a SMBIOS Running-time data block (type 161) as defined in the KEU EEPROM Specification Rev. 1.4. The running-time data block structure implements a 64bit boot counter. U-Boot on the SMARC_sAMX7 module will read the current boot counter value and increment it on every boot cycle. Current boot counter is shown as part of the information shown by the "kboardinfo" command (see description of kboardinfo).

7.12. Bootloader Update

Bootloader update on SMARC_sAMX7 is using an update script containing all necessary checks and installation commands. It is provided by Kontron on an USB thumb device containing the scriptfile and update images in the dedicated "update_smx7_spl" folder.

As an alternative it is possible to perform bootloader update from network. To achieve this, the "update_smx7_spl" folder mentioned above must have been copied to the server path of the TFTP server machine.

Given these prerequisites are met, update can be done from bootloader CLI using the predefined "update" script:

www.kontron.com // 54

=> run update

SMARC-sAMX7 User Guide. Rev. 1.5

Or, in case of network update

=> run updNet

It is recommended to use only the update script for bootloader update. This ensures that all necessary installation images are checksum controlled and copied to the appropriate location in QSPI flash.
