Hi Lars,

I've flashed your nomagic_probe firmware to a Pi Pico board. Then, I plug it in and get the following announcement on Windows:

So it looks like flashing your firmware to my Pi Pico board is a success. However, I don't find any information on how to actually use this board now.

Hardware connections

As for the hardware side, I believe I should connect my nomagic_probe board to a target Pi Pico in the following way:

The nomagic_probe would be on the left, the target Pi Pico on the right.

Is this correct?

Software

After making the connections as shown in the figure above, how should I proceed? I tried the following.

I run GDB from the GNU ARM Toolchain. Then I issue a few commands in GDB. This is what I did (PS: I'm on Windows):

You can't do that when your target is `exec'

The nomagic_probe is connected to COM11. I tried to connect to this COM-port, but I get a "Remote communication error".

What should I do?
