Hi ,

I Cant load the code or debug it in the dev board using my IAR workbench .it looks like some error with the flash loader.

Please suggest a solution to load and debug the code

The best fix is updating the EWARM to the latest version (9.something); chances are that the STM32H7A loaders are fixed there.

    I was able to connect to the HW using CubeProgrammer but not using the IAR workbench,I have tried flashing a hex file to the unit via CubeProgrammer and verified the flash contents everything looks fine, but i can't load or debug the code using the IAR Workbench.

    Hi,

    perfect.

    So we know: st-link working fine, target cpu is ok and responding.

    If problem with IAR settings, try to find out, what you set wrong there or ask at IAR about this problem.

    Seems just missing the correct flash loader -- (whatever it is ) .

      The top post references H7xx, this might not work for H7Ax

      Make sure you have current/applicable patches applied.
