can't turn off F2812 watchdog in CCS - Xiang Chao - Mar 5 8:36:55 2008



In CCS2.2, I can't change WDCR manually. It always
read 0x0000 while SCSR is 0x0005, which means
WDOVERRIDE bit is 1 and WDIS can be changed.
I just don't want to use watchdog during debug.
How to turn off it manually?
thx for any suggestion.

Hey Chao,
In your case is WDFLAG bit getting set to indicate a watchdog reset? I have written a code
where first i am setting watchdog in an interrupt mode and by purpose i am letting watchdog_isr
to execute. And after that i am configuring watchdog into Reset mode and once again letting
watchdog time out. From this experiment what i observe is system is re-executing a code but
WDFLAG bit is not getting set to indicate a watchdog reset. Any direction will be appreciated.
Thanks in advance.
