Trying the program STM32H750B-DK discovery board using STM32CubeProgrammer, but it fails. Here is the log:

Hi,

For a reason I ignore I cannot answer on the other thread so let me answer you here:

As mentioned in the other thread, the workaround mentioned by @Community member​ is only relevant for custom external loaders. When using an ST development kit such as the STM32H750B-DK you just need to select the proper external loader in the "EL" tab of the CubeProgrammer :

 STM32CubeIDE include its own version of CubeProgrammer so the same applies, open the Debug Configuration, go the the "Debugger" tab, then :

• scroll down to the "External Loader" and enable it
• click on the "scan" button to populate the menu list
• select the external loader for the STM32H750B-DK board

 

See details in section 3.4.1 (Revision 6) of the STM32CubeIDE user manual

Best regards,

Nicolas
