RTENOTITLE

Watch Dog Function

System will reboot after enable watchdog and count 60 sec :

Check default watchdog time:

RTENOTITLE

Enable watchdog, system will reboot after 60 sec.

  1. echo 1 > /dev/watchdog

RTENOTITLE

System poweroff after 60 sec. cannot reboot again

 Set timeout to 10 and pin rate to 13, the system will reboot after 10 seconds.

  1. ./watchdog-test-adv -t 10 -p 13

RTENOTITLE

RTC test

Disable RTC sync service:

  1. systemctl stop systemd-timesyncd

Set system time to current, then write to RTC:

RTENOTITLE

  1. date 110415302022 && hwclock -w && date

Set one incorrect time, then read time from RTC to verify:

RTENOTITLE

  1. date 010100002000 && hwclock -r && date

Set the system time from the RTC:

RTENOTITLE

  1. hwclock -s && date

RTENOTITLE

Storage Function Test :

SATA DISK:

  Read/write data and compare sha512 result

RTENOTITLE

RTENOTITLE

SPI Read/Write test

Write/Read/Verify data in the start/end 4 byte of flash

RTENOTITLE

  1. Note: Make sure the content of SPI nor flash is erased
  1. echo -n $'\x06\x05\x04\x03\x02\x01' > test
  1. dd if=test of=/dev/mtdblock0
  1. hexdump -C /dev/mtdblock0 -n 64
