Failed to install release firmwares

[FabienTregan]

Hi,

I have a pico clone board (the purple ones) that I can flash with the official picoprobe firmware without any problem. I want to try yapicoprobe (mainly to have RTT).

Using the latest release firmware (yapicoprobe-0120-pico-f726bca.uf2), the probe don't even enumerate. (nothing in dmesg output)

Using the previous release ( yapicoprobe-0118-pico-a7a8881.uf2 ), it probe-rs finds it but can't apparently communicate:

~/code/k-hz50$ probe-rs list
The following debug probes were found:

Output of same commands with the official debugprobe for pico firmware:

Any idea what I am doing wrong? Is the pinout the same as for the original firmware?

(I copied the udev config as said in the readme and rebooted)

thanks,
Fabien.

After building the current main commit (13dd5d1), it probe-rs list behaves as intended:

$ probe-rs info

but even after forcing RTT on:

probe-rs still can't attach RTT:

Error: Failed to attach to RTT

Caused by:
    Error attempting to attach to RTT: RTT control block not found in target memory.
    - Make sure RTT is initialized on the target, AND that there are NO target breakpoints before RTT initialization.
    - For VSCode and probe-rs-debugger users, using `halt_after_reset:true` in your `launch.json` file will prevent RTT
    initialization from happening on time.
    - Depending on the target, sleep modes can interfere with RTT.

ok... seems like I have to check the release images.

For RTT you actually have to do nothing with yapicoprobe except attaching a terminal program to one of the probes VCOM ports.

Could you please try the latest release images?: https://github.com/rgrr/yapicoprobe/releases/tag/v1.21
