How can i use J-Link Open Flashloader with STM32CubeIDE while debugging?

[Eralp]

Hi, i have a custom board with STM32H750 with qspi flash and want to debug with j-link debugger. Before i used it with st-link and my custom flashloader while debugging. Now i want to write open loader for my project but i didn't see any settings how to add this loader to STM32CubeIDE.

For example, when i select st-link in debug configurations i can select and load my custom external loader under misc section.

I have not played with this feature at all. But assuming you have a working Open flashloader you should be able to execute it from inside CubeIDE debug launch flow in two ways:

1. Debug config > Debugger > Use J-Link script file
2. Or setup an external tools configuration to let J-Flash manage execute your loader before the debug configuration is launched

Thanks for reply Mattias.

I have the exact same scenario. @Eralp​ what solution did you end up using?

Relatively broad and expanding subset of customized .STLDR external loaders for pin and flash combinations.
