Hi

I am starting to dip my toe into bare metal programming on a Pi Zero2.

Is there a way to use the Cirlce SDK with Vscode and OpenOCD for a debug and compile
enviroment ?


Thanks

I'm using an other setup, so I cannot provide info about Vscode, but JTAG debugging with OpenOCD is described in the file doc/debug-jtag.txt in the Circle project.

This guide, while for regular Pi and not Zero, should help you get VSCode set up for OpenOCD and debugging. Should be similar except for Zero specific stuff (see post by rst for that - different OpenOCD configuration files).

Thanks rst and Sean fot the reply

I'm using the PICO Probe as a SWD adapter, which hopefully should work.

I couldn't find any PI Zero specific OpenOCD settings in the doc/debug-jtag.txt file on the Circle docs page . . .

I think Zero2/Pi3 needs JTAG, not SWD.

Should be the same settings for RPi Zero 2 W like for RPi 3B. I only used JTAG debugging in AArch64 mode there. The SWD interface is different from JTAG. SWD is described in doc/debug-swd.txt, but only for RPi 5.

Though a bit late, I'm using Visual Studio 2019 (not code) with a cross-compiler and CMake on Windows.
I find it quite easy to work with, although I have not tried JTAG on this system, as most are written for Linux.
I can debug my code when it is run inside QEMU quite well, QEMU nowadays supports up to RPI4.
The one problem I have is that debugging with QEMU is broken on VS 2022. I have posted a bug on this with Microsoft, they are currently looking into it.

I'm quite happy with my setup, but will need to look into actual JTAG debugging on the board at some time.
