*Watch Dog Function*
System will reboot after enable watchdog and count 60 sec :
Check default watchdog time:
Enable watchdog, system will reboot after 60 sec.
- echo 1 > /dev/watchdog
System poweroff after 60 sec. cannot reboot again
Set timeout to 10 and pin rate to 13, the system will reboot after 10 seconds.
- ./watchdog-test-adv -t 10 -p 13
*RTC test*
Disable RTC sync service:
- systemctl stop systemd-timesyncd
Set system time to current, then write to RTC:
- date 110415302022 && hwclock -w && date
Set one incorrect time, then read time from RTC to verify:
- date 010100002000 && hwclock -r && date
Set the system time from the RTC:
- hwclock -s && date
*Storage Function Test :*
*SATA DISK:*
Read/write data and compare sha512 result
SPI Read/Write test
Write/Read/Verify data in the start/end 4 byte of flash
-
Note: Make sure the content of SPI nor flash is erased
