Raspberry pi pico can't debug

tuzik · February 3, 2023, 2:18pm

I use “wizio-pico” configuration.

Can upload firmware to pico, but click debug, nothing happens。

I had the same problem with dacoolinus。(https://github.com/Wiz-IO/wizio-pico/issues/119)

[env:raspberry-pi-pico]
platform = wizio-pico
board = raspberry-pi-pico
framework = baremetal

build_type = debug

upload_protocol = picoprobe
debug_tool = picoprobe

This is my “platformio.ini”

Can someone help me, thanks a lot

You follow the instructions DEBUG · Wiz-IO/wizio-pico Wiki · GitHub?

What text is appearing the “Debug Console” tab in VSCode?

tuzik · February 3, 2023, 2:24pm

I press and hold “BOOTSEL”, plug in the USB cable, and upload the firmware. But uploading the firmware again nothing happens. I can only unplug the USB cable again and repeat the previous operation.

tuzik · February 3, 2023, 2:28pm

This is my device manager.

I follow“ https://github.com/Wiz-IO/wizio-pico/wiki/DEBUG#picoprobe ”Operation,Nothing will change

maxgerhardt · February 3, 2023, 2:32pm

You still didn’t answer my question on what output appears in the “Debug Console”.

Also, open a terminal and dp

git clone https://github.com/Wiz-IO/tool-pico-openocd
cd tool-pico-openocd
windows\picoprobe.exe -s share\openocd\scripts -f interface/picoprobe.cfg -f target/rp2040.cfg

What is the output?

tuzik · February 3, 2023, 2:34pm

Click the debug button, nothing

maxgerhardt · February 3, 2023, 2:36pm

I can’t read chinese but I mean the “DEBUG CONSOLE” tab in VSCode. Even if it’s empty that’s good information

tuzik · February 3, 2023, 2:37pm

Yes, he is empty. Only compile information, click debug, nothing prints

maxgerhardt · February 3, 2023, 2:39pm

maxgerhardt:

open a terminal and dp

git clone https://github.com/Wiz-IO/tool-pico-openocd
cd tool-pico-openocd
windows\picoprobe.exe -s share\openocd\scripts -f interface/picoprobe.cfg -f target/rp2040.cfg

What is the output?

Then please do as instructed here.

After I uploaded the firmware, my device manager could not find the PICO device.

So you did flash one Pico the picoprobe.uf2 firmware and changed the driver for “Picoprobe (Interface 2)” to WinUSB using Zadig? Because if yes, it should work.

No picoprobe device

maxgerhardt · February 3, 2023, 2:59pm

Why is there a CMSIS-DAP debugger? You’re supposed to be uploading tool-pico-openocd/picoprobe.uf2 at main · Wiz-IO/tool-pico-openocd · GitHub to your the Pico that you want to be your Picoprobe, that one doesn’t expose a CMSIS-DAP debugger.

tuzik · February 3, 2023, 3:02pm

Do you mean that I need to upload picoprobe.uf2 with CMSIS-DAP to appear picoprobe device

maxgerhardt · February 3, 2023, 3:06pm

No.

You have two Raspberry Pi Picos. One of them you designate to be the Picoprobe, the other one to run your firmware.
You disconnect all cables between them (USB, jumper cables).
You take the Pico that is supposed to become the Picoprobe, hold down the BOOTSEL button and plug it into your computer via USB.
The bootdrive should appear.
You drag and drop the picoprobe.uf2 file into the bootdrive.
The Pico is now programmed to be the Picoprobe and should automatically reboot.
You should now see “Picoprobe (Interface 2)” as a device in Zadig.
Change the driver to WinUSB.
Rerun the windows\picoprobe.exe -s share\openocd\scripts -f interface/picoprobe.cfg -f target/rp2040.cfg command with still only the Picoprobe plugged. It should now not say "Error: Can’t find a picoprobe device! " anymore, but should complain that it cannot find a chip connected to the Picoprobe. Is that correct?

tuzik · February 3, 2023, 3:12pm

I always thought it would be done with one PICO.

OK, I see. Thanks for your answer, I started to try.Good night.

maxgerhardt · February 3, 2023, 3:14pm

Picoprobe involves 2 Picos: One is the debugging probe, one is the board getting debugged.

tuzik · February 3, 2023, 3:17pm

Yes. I didn’t read these documents, and many problems occurred because of ignoring these documents. Thank you so much

tuzik · February 10, 2023, 12:53pm

Sorry to bother you again. My pico still can’t debug.
