Can I use the RPi Debug Probe on a Pi 4

Sun Dec 01, 2024 1:18 pm

Hi I was watching a video on the Debug probe and they said it can be used to debug Pi boards. Is it possible to debug a Pi 4 with it? I have a Pi 4 that does not work, and I tried fixes that was said to me on a previous forum post but none of them helped.

Did you follow the suggestions in the boot problem sticky as thagrol suggested?

If so what were the results?

I'm not aware of what debug probe you have, perhaps providing us with a link would help?

If your "debug probe" is one of these: https://www.cpmspectrepi.uk/raspberry_p ... Probe.html then, yes, via the appropriate GPIO connector cable supplied with the probe. However, if you don't have that probe a "good value" alternative is one of these USB to serial (3.3V) devices: https://www.cpmspectrepi.uk/raspberry_p ... nsole_Stub (there are other, alternative, serial devices within that page).

Running Bookworm on a Pi5, a P500 and two P4B's but still using Bullseye or Buster on other (older) Pi's and the P400 I often post from. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm for notes & screenshots etc.

I did follow the suggestions and there wasn't really any difference, it was a while ago, So I don't really remember what happened.

That's the one I have and I ended up finding the answer in the docs eventually. Thanks

I did? When?
