The TYPE pins indicate to the Carrier Board the Pin-out Type that is implemented on the module. The pins are tied on the module to either ground (GND) or are no­connects (NC). For Pinout Type 1, these pins are don’t care (X).
TYPE2# TYPE1# TYPE0# X X X Pinout Type 1
NC NC NC Pinout Type 2 NC NC GND Pinout Type 3 (no IDE) NC GND NC Pinout Type 4 (no PCI) NC GND GND Pinout Type 5 (no IDE, no PCI) GND NC NC Pinout Type 6 (no IDE, no PCI)
The Carrier Board should implement combinatorial logic that monitors the module TYPE pins and keeps power off (e.g deactivates the ATX_ON signal for an ATX power supply) if an incompatible module pin-out type is detected. The Carrier Board logic may also implement a fault indicator such as an LED.

5. Smart Embedded Management Agent (SEMA)

The onboard microcontroller (BMC) implements power sequencing and Smart Embedded Management Agent (SEMA) functionality. The microcontroller communicates via the System Management Bus with the CPU/chipset. The following functions are implemented
¾ Total operating hours counter counts the number of hours the module has been run in minutes. ¾ On-time minutes counter counts the seconds since last system start. ¾ Temperature monitoring of CPU and board temperature minimum and maximum temperature values of CPU and board are stored in
flash.
¾ Power cycles counter ¾ Boot counter counts the number of boot attempts. ¾ Watchdog Timer (Type-II) Set / Reset / Disable Watchdog Timer. Features auto-reload at power-up. ¾ System Restart Cause Power loss / BIOS Fail / Watchdog / Internal Reset / External Reset ¾ Fail-safe BIOS support In case of a boot failure, hardware signals tells external logic to boot from fail-safe BIOS. ¾ Flash area 1kB Flash area for customer data ¾ 128 Bytes Protected Flash area Keys, IDs, etc. can be stored in a write- and clear-protectable region. ¾ Board Identify Vendor / Board / Serial number / Production Date ¾ Main-current & voltage monitors drawn current and main voltages
For a detailed description of SEMA features and functionality, please refer to the SEMA Technical Manual and SEMA Software Manual, downloadable at:
Note: Due to limitations of the Intel “Bay Trail” platform, SEMA can only obtain CPU temperature readings when the OS is running.
http://www.adlinktech.com/sema

5.1. Board Specific SEMA Functions

5.1.1. Voltages

The BMC of the cExpress-BT2 implements a voltage monitor and samples several onboard voltages. The voltages can be read by calling the SEMA function “Get Voltages”. The function returns a 16-bit value divided into high-byte (MSB) and low-byte (LSB).
ADC Channel Voltage Name Voltage Formul a [V]
0 CPU-Vcore (MSB<<8 + LSB) x 3.3 / 1024 1 GFX-Vcore (MSB<<8 + LSB) x 3.3 / 1024 2 +V1.05S (MSB<<8 + LSB) x 3.3 / 1024 3 Vmem (MSB<<8 + LSB) x 3.3 / 1024 4 +V1.0V (MSB<<8 + LSB) x 3.3 / 1024 5 +V3.3V (MSB<<8 + LSB) x 1.1 x 3.3 / 1024 6 +VIN (MSB<<8 + LSB) x 6.000 x 3.3 / 1024 7 (MAIN CURRENT) Use Main Current Function

5.1.2. Main Current

The BMC of the cExpress-BT2 implements a current monitor. The current can be read by calling the SEMA function “Get Main Current”. The function returns four 16-bit values divided in high-byte (MSB) and low-byte (LSB). These 4 values represent the last 4 currents drawn by the board. The values are sampled every 250ms. The order of the 4 values is NOT in chronological order. Access by the BMC may increase the drawn current of the whole system. In this case, there are still 3 samples not influenced by the read access.
Main Current = (MSB_n<<8 + LSB_n) x 8.06mA

5.1.3. BMC Status

This register shows the status of BMC controlled signals on the cExpress-BT2.

cExpress-BT2 Page 35

5.1.4. Exception Codes

In case of an error, the BMC drives a blinking code on the blue Status LED (LED1). The same error code is also reported by the BMC Flags register. The Exception Code is not stored in the Flash Storage and is cleared when the power is removed. Therefore, a “Clear Exception Code” command is not needed or supported.
Exception Code Error Message
0 NOERROR 2 NO_SUSCLK 3 NO_SLP_S5 4 NO_SLP_S4 5 NO_SLP_S3 6 BIOS_FAIL 7 RESET_FAIL 8 POWER_FAIL 9 LOW_VIN 10 VCORE 11 VGFX 12 V1P05S 13 VMEM 14 V1P0A 15 V3P3A 16 +P12V_5V 18 CRITICAL_TEMP 19 NO_CB_PWROK 20 NO_HW_PWORK 21 NO_V1P24A_PG

5.1.5. BMC Flags

The BMC Flags register returns the last detected Exception Code since power-up and shows the BIOS in use and the power mode.
Bit Description
[ 0 ~ 4 ] Exception Code [ 6 ] 0 = AT mode
1 = ATX mode
[ 7 ] 0 = Standard BIOS

8. BIOS Checkpoints, Beep Codes

This section of this document lists checkpoints and beep codes generated by AMI Aptio BIOS. The checkpoints defined in this document are inherent to the AMIBIOS generic core, and do not include any chipset or board specific checkpoint definitions.
Checkpoints and Beep Codes Definition
A checkpoint is either a byte or word value output to I/O port 80h. The BIOS outputs checkpoints throughout bootblock and Power-On Self Test (POST) to indicate the task the system is currently executing. Checkpoints are very useful for debugging problems that occur during the preboot process.
Beep codes are used by the BIOS to indicate a serious or fatal error. They are used when an error occurs before the system video has been initialized, and generated by the system board speaker.
Aptio Boot Flow
While performing the functions of the traditional BIOS, Aptio 5.x core follows the firmware model described by the Intel Platform Innovation Framework for EFI (“the Framework”). The Framework refers the following “boot phases”, which may apply to various status code & checkpoint descriptions:
Security (SEC) – initial low-level initialization
Pre-EFI Initialization (PEI) – memory initialization
Driver Execution Environment (DXE) – main hardware initialization
1
2
Boot Device Selection (BDS) – system setup, pre-OS user interface & selecting a bootable device (CD/DVD, HDD, USB, Network, Shell, …)
Viewing BIOS Checkpoints
Viewing all checkpoints generated by the BIOS requires a checkpoint card, also referred to as a OST Card or POST Diagnostic Card. These are PCI add-in cards that show the value of I/O port 80h on a LED display.
Some computers display checkpoints in the bottom right corner of the screen during POST. This display method is limited, since it only displays checkpoints that occur after the video card has been activated.
Keep in mind that not all computers using AMI Aptio BIOS enable this feature. In most cases, a checkpoint card is the best tool for viewing AMI Aptio BIOS checkpoints.

9.2. Thermal Solution

9.2.1. Heat Spreaders

The function of the heat spreader is to ensure an identical mechanical profile for all COM Express modules. By using a heat spreader, the thermal solution that is built on top of the module is compatible with all COM Express modules.

9.2.2. Heat Sinks

A heat sink can be used as a thermal solution for a specific COM Express module and can have a fan or be fanless, depending on the thermal requirements.

9.2.3. Installation

Install a heat spreader or heat sink using the following instructions. Step 1: Before mounting the heatsink, install the required memory modules onto the SODIMM socket(s) on the COM Express module.
Step 2: Remove the protective membranes from the thermal pads.
Step 3: Assemble the heatsink onto the COM Express module. Use the four M2.5, L=6mm screws provided to fasten the heatsink to the module.
Step 4: Place the COM Express module and heatsink assembly onto the connectors on the carrier board as shown.
Then press down on the module until it is firmly seated on the carrier board. Step 5: Use the five M2.5, L=16mm screws provided to secure the COM Express module to the carrier board from the solder side.
cExpress-BT2 Page 71
Step 6: If you are installing a heatsink with a fan, plug the fan connector into the carrier board as shown.

9.3. Mounting Methods

There are several standard ways to mount the COM Express module with a thermal solution onto a carrier board. In addition to the choice of 5 mm or 8mm board-to-board connectors, there is the choice of Top and Bottom mounting. In Top mounting, the threaded standoffs are on the carrier board and the thermal solution is equipped with through-hole standoffs. In Bottom mounting, the threaded standoffs are on the thermal solution and the carrier board has through-hole standoffs.
