Cannot debug STM32MP157DAC1 ( core M4 )

[samuelG4953]

Hello,

We used pluging cortex-debug with microprocessor STM32MP157DAC1. In this micro they are 2 cores : (A7 for linux and M4). We try to debug the M4 with linux running (A7 running).

With this microprocessor we can debug M4 with 2 modes :

• Engineering Mode (No linux running)
• Production mode (Linux running)

If we debug M4 with engineering mode : the debug is ok with vscode plugin : cortex-debug

Now we want debug with linux running (production mode) because we need inter-processor communication (A7 and M4) . We need debug with application OPENAMP used . With Stm32CubeIDE : it's working , the firmware is loaded in SSH into linux and the prgram M4 is started by linux and the debug probe only connect to the firmware without restarted (hot plug). it's posible to do the same with pluging cortex-debug ?
