Hi,
I’m using latest u-boot master
(9b416a9f4ca7cf5ac4d5f7143d67edde7f7d7326) running on beaglebone
(white). This board has watchdog enabled by default for 60 secs
timeout but in my case it’s not resetting board after that amount of
time. I did check watchdog registers:
U-Boot# md.l 0x44e35000 30
44e35000: 502a0501 00000000 00000000 00000000 …*P…

44e35050: 00000000 00000000 00000000 00000000 …
and it seems value in register WDT_WCRR doesn’t increment → it could
mean that 32kHz clock isn’t working? I try to switch between internal 32KHz and PLL 32KHz but both doesn’t work.
Any other ideas what to check?
Thanks.
