I'm using a STM32F746-Discovery kit and the development is being done on a linux PC using Trustudio 9.3.0. Watchdog is going off and I can't connect to reprogram

As mentioned above I can't connect as the watchdog is continuously going off. I used the STM32CubeMx to enable the IWDG and it created the s/w load which enables the IWDG but doesn't refresh it. I know how to fix it in the s/w but my debugger under TrueStudio won't connect to load the new image. My board is continuously resetting.

Have I bricked my board or is there some s/w tool I can use to erase the board? Remember I am running on linux.

Thanks in Advance for any help.

Cheers!!

If you enabled the IWDG hardware start, this can be disabled by using the STM32CubeProgrammer by setting some option bytes (OB).
