probe-run missing permissions on m1 Mac. #355

Closed letto4135 closed 1 year ago

letto4135 commented 1 year ago

After following https://github.com/rp-rs/rp2040-project-template the project fails to run, on 2 different pico models and a waveshare rp2040-plus and several different cables. The RP2040 shows up in the finder, so it is a data cable. No documentation or issues that I can find on mac, only linux and windows.

probe-run --list-probes
Error: no probe was found.

Common reasons for this are faulty cables or missing permissions.
For detailed instructions, visit: https://github.com/knurling-rs/probe-run/tree/2f138c3#troubleshooting

Running probe-run --chip RP2040 --list-probes also results in the same issue.

Note: the instructions on the linked repo for elf2uf2-rs do work, but the instructions for cargo-embed do not because it relies on probe-run as well...

Which debug probe are you using?

Quoting from the rp2040-project-template README:

If you aren't using a debugger, check out [alternative runners](https://github.com/knurling-rs/probe-run/issues/355#alternative-runners) for other options

Note that there is a difference between loading the flash through the RP2040 ROM bootloader in USB Mass Storage Device mode (which is what elf2uf2-rs uses), and using a debugger to program Flash and control the CPU core via the SWD/SWCLK pins (which probe-run requires).

It is possible to get the RP2040 to appear as its own USB debugger - the debugger code runs on one core and you get to program the other. I haven't tried that approach though and there are plenty of reasons why it might not work so I would always recommend a hardware debugger.

Yup my bad, didn't see the debugger part, thanks.
