Eurotech provides a Linux operating systems based on Yocto framework (www.yoctoproject.org) as well
as an SDK for application development.
All the documentation for the developer is available from:www.yoctoproject.org/documentation.
12.2 The bootloader procedure
The bootloader procedure is the following:
1. The MLO file is loaded from either the external microSD card or the onboard eMMC memory, and
saved in the on-chip memory to configure the RAM memory for use
2. The u-boot.img file is loaded (from the same device where MLO was loaded from), saved in the
RAM memory, and executed
3. The bootloader searches for a valid operating system. The search order is:
a. microSD card
b. eMMC
4. The bootloader fetches the Linux kernel (/boot/zImage) and the device tree (/boot/reliagate-10-
11.dtb), and boots the operating system up
12.2.1 How to select the MLO source
The MLO file can be loaded from either the external microSD card or the onboard eMMC memory,
according to the setting of the Boot selection jumper (JP2):
l JP2 inserted = MLO file loaded from the micro-SD card
l JP2 removed = MLO file loaded from the eMMC and, if not found, from the microSD card
12.2.2 How to set up a correct microSD card / eMMC card partition
To allow the correct bootloader procedure, the microSD card and the eMMC memory have to be configured
with at least these 2 partitions:
l 1st partition:
o
Type: FAT16
o
Flags: lba, boot
o
Contains the files: MLO and u-boot.img
l 2nd partition:
o
Type: ext4
o
Contains the operating system, including the Linux kernel (/boot/zImage) and the device tree
(/boot/reliagate-10-11.dtb)

14.9 Watchdog
The ReliaGATE 10-11-16 exposes the watchdog as follows:
l Watchdog: /dev/watchdog1
14.9.1 Manage the watchdog using the C programming language
To manage the watchdog using the C programming language use the following commands:
Int interval;
Int bootstatus;
Long value;
/* display current watchdog value */
If (ioctl(fd,WDIOC_GETTIMEOUT,&interval)==0)
{
// interval contains current timeout in seconds
}
/* Check if lasdt boot is caused by watchdog */
If (ioctl(fd,WDIOC_GETBOOTSTATUS,&bootstatus)==0)
{
//bootstatus <> 0 Watchdog
//bootstatus = 0 Power-on reset
}
/* set the watchdog value (for example: 30 seconds) */
value=30;
If (ioctl(fd,WDIOC_SETTIMEOUT,&value)==0)
{
//Watchdog has been set to value content
}
/* stop the watchdog */
write(fd,”V”,1);
/* feed the watchdog */
ioctl(fd,WDIOC_KEEPALIVE,0);
14.9.2 Manage the watchdog from the command line
To set the watchdog value (for example: 30 seconds), use the following command:
wdt_setup –d /dev/watchdog1 –t 30
To feed the watchdog, use the following command:
echo 10 >/dev/watchdog1
To stop the watchdog, use the following command:

14.10 RTC
The ReliaGATE 10-11-16 exposes the user-available RTC as follows:
l RTC: /dev/rtc1
The "/dev/rtc1" offers:
l three timestamp registers
l one user-available byte.
14.10.1 How to use the timestamp registers
The timestamp registers are the following:
Timestamp register What it contains
sys/class/rtc/rtc1/device/timestamp1 Reserved data
sys/class/rtc/rtc1/device/timestamp2 The timestamp that the system last lost power (only if a
successful initialization has been achieved)
sys/class/rtc/rtc1/device/timestamp3 The timestamp that the system last has been powered
(only if a successful initialization has been achieved)
You can only read and reset the timestamp registers.
To read the timestamp2, use the following command:
cat /sys/class/rtc/rtc1/device/timestamp2
To reset the timestamp2, use the following command:
echo timestamp2 > /sys/class/rtc/rtc1/device/resets

14.10.2 How to use the user-available byte
The user-available byte is the following:
User-available byte What it contains
/sys/class/rtc/rtc1/device/ram_byte The default value is 0.
You can write in it a value included in the range: 0 to 255.This
value is retained as long as the /dev/rtc1 device receives a
valid power supply (main power supply or battery)
You can read and write the user-available byte.
To read the byte, use the following command:
cat /sys/class/rtc/rtc1/device/ram_byte
To write 112 in the byte, use the following command:
echo 112 > /sys/class/rtc/rtc1/device/ram_byte
14.10.3 How to automaticallly wake the ReliaGATE 10-11-16 up from the sleep mode
To wake the ReliaGATE 10-11-16 up 20 seconds after the current date and time, use the following
commands:
#set current date
DATE=”09/04/2015”
TIME=”10:00:00”
date +”%m/%d/%y %H:%M:%s” –s “$DATE $TIME”
rtctest –d /dev/rtc1 –a “04/09/2015 10:00:20”
echo mem >/sys/power/state
