Dear Nashiing,

the WD error counter and Fault error counter are functional in the DEBUG mode, but the watchdog does not require refresh. Please reset the FS65 before you try to burn the program.

Thanks fo your reply . i have config the WD function right in debug mode, then i exit the debug mode, but i find that when i burn the program ,the tc275 need to reset itself, which cause the tc275 can't  answer the WD in FS6500,  which cause the FS6500 to DFS mode, the core supply for tc275 lose.   how can i solve this situation,  Thank you

Dear Nashiing,

the watchdog must be refreshed every open window in Normal mode. 

But you can extend the watchdog window up to 1024ms.

How long does it take the TC275 to restart? Perhaps you can set the watchdog window to the maximum value 1024ms and the TC275 will be able to restart and send the watchdog refresh within the 1024ms.

With Best Regards,

Jozef

thanks for your reply, i have known the answer, the only way to settle the problem is to config the sbc in debug mode.

because the FS6500 in normal mode, and when the TC275 burnding program , there have a 100ms low level in porst pin, which cause the system don't work
