[U-Boot] i.MX6 based board does not work if watchdog support is enabled
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

I set it originally to 10000 and later to 128000 and in the end removed it. It kept doing it wrong.

No, it shouldn't be an issue. Does the attached patch help?
Thanks,

Can you resend the patch in the usual way to ML for including into mainline ?
Thanks, Stefano
