Arduino IDE 2.2.1 debug failure

@wwatson @Merlin513 @ptillisch:
Some success :smiley:
I downloaded the latest version of the JLINK software:

I created the debug_custom.json file:

{
  "servertype": "jlink",
  "device": "STM32H747XI_M7",
  "interface": "SWD",
  "serverpath": "D:/Program Files/SEGGER/JLink_V794/JLinkGDBServerCL"
}

Note: Update the above to where you installed the JLINK code. ..

Edit: wondering if other debugger modules will work as well, like the STLink/V2
Or the Tinde cmis-dap (likewise Pico)?
