Part Number: TMS320F2800157
Other Parts Discussed in Thread: C2000WARE

Hi Team,

hardware: F2800157 CC

software: C:\ti\c2000\C2000Ware_5_01_00_00\driverlib\f280015x\examples\gpio-->gpio_ex2_toggle

I changed the GPIO toggle frequency from 1s to 100us for observe easily.

I just add watchdog by syscfg(The default mode of watchdog is reset mode):

But the device can not reset properly.

I observed the device pushed the XRSn pin low about 50us. But the program can not run after reset, and PC pointed to this place:

CH1 Yellow GPIO

CH3 Purple XRSn

Should I take some other operations of watchdog or other modules for properly reset?

Thanks & Regards

device is getting reset but after reset it's not jumping to flash because when device is connected with CCS, it boots as per emulation boot and you have not set that to boot from flash. In CCS menu, under the "Scripts", please select "EMU_BOOT_FLASH" and then issue reset and run the test and see if it works.

Thanks Vivek, It works.

I also tried to program to flash, then changed the boot mode to boot to flash, also resolved the issue.
