STM32CubeProgrammer v2.7.0 Erase error

[Hans T]

Since I am using the version v2.7.0, I get this error after programming both cores after the first time:

I can fix this by Disconnecting the STM32H7, and Connected again

Hi @Hans T​ 

According to your debug traces your M7 application seems to be doing something perturbing Flashloader operations.

Let me explain what you are doing exactly :

• You are programming Bank 1 and Launching the programmed application by M7.
• Then you program another application (seems to be your M4 appli) in Bank2 and you launch the progammed application by M7 too (not M4) , am I correct?

What I recommend :

• Program the M4 application (in bank2) (without launching it).
• Program the M7 application (in bank1) and launch it.

Hope it helps.
