TMS320F280040: TMS320F28004x - Software reset via the Watchdog

Part Number: TMS320F280040

Hello Team,

For the TMS320F28004x there is no Software reset available and a recommended solution would be using the Watchdog for generating it.

Without having the emulator connected, I run the software and make it call my reset function as below.

The Reset does not look to work since I get to the instruction after the reset.

  • What may prevent the function to reset the device?

 When i start the SW with connected emulator and stop at the beginning of main routine the value of

WdRegs.WDCR.bit.WDDIS is already 1

afterwards the value could not be changed, it seams to be locked.

  • Do you known, if there are some project settings that disable watchdog an lock it?

Thanks,

SunSet
