[U-Boot] watchdog not resetting beaglebone after timeout period
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............ 44e35010: 00000010 00000001 00000000 00000000 ................ 44e35020: 00000000 00000020 ffe2005e ffe20000 .... ...^....... 44e35030: ffffedcb 00000000 00000000 00000000 ................ 44e35040: 00000000 00000000 00004444 00000000 ........DD...... 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? Any other ideas what to check? Thanks.

I just checked on my BBB and with falcon mode it's tripping the reset.

Hmm I don't have BBB by hand but I tested on BB without falcon mode and it's not working.
