Watchdog Reset just by it self.

[darksoul]

my vocore keeps rebooting about 5 time per day.
it only runs VPN connection to my server.
also the DTS for second UART was changed.

thats what I'm getting in the terminal.



any one has an idea what can do this?

or where can i look for the problem?

First of all you could disable the Watchdog Interrupt (Write 1 to Offset 0x238, Bit 2) and check wether your resets come again. You could (after a reset occured) check 0x038 Bit 1 -> should be set if it was really a WDT_RESET.

Are you using Timer 1? This timer is also used as Watchdog, depending on 0x128 Bits 4-5 (Timer 1 Control Register, Mode) - check if these bits are 11b (WDT mode).

I am having some watchdog issues with a recent build. Mine occur at bootup, sometimes the watchdog will cause a reboot soon after a power up. If it stays up for 10-15 minutes it seems it will stay up forever.

I think this may be related to kernel 3.14, I have switched back to 3.10 and this disappeared. Does your VoCore have watchdog issues if you use the image at http://vonger.cn/upload/vocore.v1.0.bin?
