ESP32-Pico-V3 fails to upload/debug using esp-prog

yes absolutely, that folder is there!

Please remove ~/.platformio/penv folder and restart VSCode. Does ~/.platformio/penv/bin/python --version work?

yes it works, version 3.8.4, removing penv folder did not make a difference.

@valeros very same symptoms with a blink :frowning:

Could you please try erasing the entire flash memory? Just type pio run -t erase in the IDE terminal and try to debug the blink example again. Also would be great if you could attach here all log messages.

This got us one step further. It does now stop at app_main, despite it not being stated in the platformio.ini in the blink project. It also stops at the first line in the loop. However if I try to step over it jumps into `start_cpu0_default.dbgasm’ at line 52 and wont ever jump back into the loop function.

Full log where i step over the first line in loop, and press resume after it jumped into start_cpu0_default.dbgasm:

Also the python problem is still unresolved.

Looks like you’re using the stable version of espressif32 platform, you need to use the upstream version:

[env:esp32dev]
#platform = espressif32
platform = https://github.com/platformio/platform-espressif32#feature/openocd-update
board = esp32dev
framework = arduino
monitor_speed = 115200

platformio.ini contains this exact line:

[env:esp32dev]
platform = https://github.com/platformio/platform-espressif32#feature/openocd-update
board = esp32dev
framework = arduino

yes at this point I also find this whole issue highly confusing.

edit: also if I really was using the stable version, uploading and debugging with the updated openocd version would not work at all as indicated early in this thread.

For some reason an old command program_esp32 used for programming. Are you sure you’re using the latest development version of platformio-core? What is the output of pio --version command?

wth
5.0.1 :scream:
why that again? I did run pio upgrade --dev and it said it’s on 5.0.2

trying again with 5.0.2b3

EDIT: disregard below, i have removed the breakpoint and started without breakpoint and it now works as expected :scream:

before edit:
@valeros it would have been boring if it worked now, wouldn’t it? :man_facepalming:

I’ve tried 3 times, also erased flash again to make sure.

At least we have set up proper environment for experimenting. Just to be sure, you didn’t enable flash encryption or secure boot?

Please see the edit on top valeros! Resetting the breakpoint did the trick!

I have just also tried debugging the big project and it seems to be working just fine :hugs:
Thank you very much for your amazing support!!

The only thing remains is python --version still reports 2.7.16, although since everything else works I can only imagine it’s a glitch :thinking:

Thanks to your work my debug session now works as well with the updated platform and core. The program comes to a halt at least at setup(). :+1:

It does not recognize my breakpoint set manually after it halted a few lines down, though. I will have to experiment a bit to find why, I think.

I cannot see why this is not stopping at the breakpoint:

The program is running as if no breakpoint would have been there :confused:

[update]
Never mind. While writing this I think I found the solution myself: the code at line 143 was meant to initialize some global array and seemingly has been executed at compile time already. Optimization indeed :grin:
