TMS320F28069: watch dog restart location

ken ho1

Hi,

I use watch dog to reset the device. It did generate a reset on pin XRSn.

However, the device doesn't restart on application. It restarts on 0x3FF4FA on debug mode. It doesn't work on non debug mode either.

The TDO is 1. TRSTn is 0. GPIO34 is 1.

Please advise.

Hi,

Have you check the BOOTMODE pins setting to make sure they are driven to have BOOT to Flash?

Not sure if I understand this question correctly but to change value at any memory location, open that location in CCS memory browser and update the value. Right?

Does your application run fine when you powerup the board?

Yes, I got the system reset working by changing the memory location under ccs debugger.
When the watch dog kick in, it did restart the whole system.
