SK-AM62B-P1: Setting up OpenOCD gdb port within VS Code

Ayman Ghanem

Part Number: SK-AM62B-P1

Hello,

I'm trying to setup OpenOCD for gdb debugging within VS code in my WSL2 environment. I installed the two TI VS code extensions (TI Embedded Debug and TI Embedded Development). Now, when I start a debug session, the script is trying to setup OpenOCD with ports 50000 and up. For some reason, I get a bind error on port 50001 because it is in-use. I ran lsof and netstat and didn't find any process using that port, so not sure who is using it. So, I went into scripts/board/ti_am625evm.cfg and added this line to use port 3333 instead:
gdb_port 3333

Now, OpenOCD starts fine on that port and creates gdb servers on ports 3333-3339 for the different cores. However, when arm-none-eabi-gdb is started, it is still trying to connect to OpenOCD remote target using port 50000 and it fails. How do I tell the startup script to use port 3333 instead of 50000 for both openocd and arm-none-eabi-gdb? I tried adding this line in my launch.json but it didn't like that property:

"miDebuggerServerAddress": "localhost:3333"

I'm attaching my launch.json from the project's .vscode directory and the terminal/console logs when starting openocd and arm-none-eabi-gdb.

Thanks.

Hi Ayman,

miDebuggerServerAddress is a cppDbg field. It will not be recognised by "cortex-debug".

Can you try removing it, change servertype to external?

}

Run openocd separately before launching the config.

openocd -f ./interface/xds110.cfg -f ./board/ti_am625evm.cfg
