Hello,
I am trying to add support for watchdog in one board and it is not working as expected.
I did add the:
#define CONFIG_HW_WATCHDOG #define CONFIG_IMX_WATCHDOG
into the board config file.
Into the board .c file, I added:
int board_late_init(void) { ... #ifdef CONFIG_HW_WATCHDOG hw_watchdog_init(); #endif
return 0; }
and the hw_watchdog_init is indeed called.
It starts booting and shows:
U-Boot 2013.10-rc3-00046-gc1c2434-dirty (Sep 28 2013 - 21:12:53)
CPU: Freescale i.MX6Q rev1.2 at 792 MHz Reset cause: WDOG Board: yyyy DRAM: 1 GiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 In: serial Out: serial Err: serial Net:�
and it in fact resets.
I am booting the board from USB loader. May it be an issue?
I have read the code and briefly compare with linux one and seems the setting on the register is ok and default is 128secs if CONFIG_WATCHDOG_TIMEOUT_MSECS is not define.
are you sure that you don't change this define?
CONFIG_WATCHDOG_TIMEOUT_MSECS
