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.

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?
