Older STM32H743ZI MCU Nucleo board was updated to V3.J10.M1 firmware version. While The board can be flashed, it isn't possible to debug or erase chip memory. Is there a way to roll back the update?

[GToml.1]

After running into some issues during an OS migration, I ran a firmware update on a nucelo_h743zi board using the stLink utility. After this I ran into many issues with flashing and debugging.

While I can flash the board with openocd v11, it has some errors which I have attached. I also cannot debug the board using gdb or connect to it using stlink utility.

Is there a way to revert the firmware to it's old version (V2.J2.MX?)

Not clear how you'd get ST-LINK/V3 firmware onto an ST-LINK/V2

ST does not provide binary recovery images for the ST-LINK firmwares.

@Community member​ Thanks for responding. You are correct; I mistakenly put V2.J2.Mx. It was at V3.J2.M1. But this helps. I updated the firmware to V3.J10.M1 and I can debug, flash, and connect with the stlink utility v4.6.0.
