ESP-PROG - openocd path contains "undefined"

I want to debug my ESPCam with esp-prog. When I click on quick access-> Debug-> start debugging, the terminal shows the make output.
udev rules are installed.

The output terminal shows:

undefinedWarning! Ignore unknown configuration option `upload_tool` in section [env:esp32cam]
Warning! Please install `99-platformio-udev.rules`.

Needless to say that debug does not start, I guess it has something to do with “undefined” in the opeocd path. Has anyone an idea what causes the above errors ?

There is no upload_tool, only upload_protocol (and debug_tool).

The Xtensa32-GDB binary expects certain dynamic libraries to be installed in your system, it is not linked statically. This has already been discussed before at Problem with esp32 debug for Ubuntu. (undefined symbol: _Py_ZeroStruct) - #13 by maxgerhardt. In your case it looks like you need at least

sudo apt install python2.7 libpython2.7 libusb-1.0-0

or whatever packet manager your distribution uses.

sudo apt install python2.7 libpython2.7 libusb-1.0-0

shows it is already installed.
where does that “undefined” in the path come from ?

undefined/home/john/.platformio/packages/tool-openocd-esp32/bin/openocd: error while loading shared libraries: libusb-1.0.so.0: cannot open shared object file: No such file or directory

Good question, I remember getting that too, but it has no effect whatsoever.

Then it starts up now? Or what does

ldd ~/.platformio/packages/toolchain-xtensa32/bin/xtensa-esp32-elf-gdb

output?

What happens on the commandline when you directly execute it?

and what’s the latest output when you start debugging in VSCode + PlatformIO?

it appears to work. Output is

when build is complete, the whole build output also shows up in the debug window with this added:

   undefined/home/john/.platformio/packages/tool-openocd-esp32/bin/openocd: error while loading shared libraries: libusb-1.0.so.0: cannot open shared object file: No such file or directory

What is strange though is that after I hit the debug button, two tasks show up on the call stack window (left part of screenshot). Shortly after that I sometimes get a pop up error that complains about multiple requests to rebuild the code index. I get the feeling that somehow two tasks are triggered when I hit debug.

grafik

Something is very wrong there. If it starts up in the shell, and PlatformIO uses has the same environment available, it should start up. It makes no sense.

Can you

  1. disable all other extensions except C/C++ by Microsoft and PlatformIO,
  2. Grab the known-good project at https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-blink
  3. Import it and switch to it using the project environment switcher
  4. Select the “PIO Debug (espidf-blinky)” configuration in the debugger, and start debugging?

No success. I did

  1. remove VSCode completely, reinstall it.
  2. install platformio.
  3. copy the contents of the “known good” git folder (extracted the zip)
  4. open vscode, On the platformio welcome screen click open project.
  5. go to espidf-blink
  6. klick the platformio icon on the left, choose build

output is:

Indeed, there is no .pio folder… not even a hidden one.

Since the systax highlighting in the code errored that arduino.h could not be included, I also installed the arduino add-on- but with no success. I guess its a highlighting error since it is not showing up in the output.

ok, I was using the espidf-Ardunino example, but its the same for the other one:

grafik

But that’s a different error now, try resolving it via Problems building with ESP-IDF latest version (4.3.0) - #4 by maxgerhardt.

(The file should be locally in <home folder>/.platformio/packages/framework-espidf/components/mbedtls/esp_crt_bundle/cacrt_all.pem)

disabling the certificates package with the menu did the trick. Just deleting the one mentioned in the topic did not.
Also, I did add to platformio.ini:

upload_port = /dev/ttyUSB1
debug_tool = esp-prog
debug_port = /dev/ttyUSB0
debug_init_break = tbreak loop

I noticed that before firing up the debugger, pio-devices show both, USB0 and 1 available. I did successfully upload via USB1 before, so USB0 must be the JTAG,
After activating the debugger USB0 is gone. If I re-plug the esp-prog adapter, it re-appears.

Your debug port is not a serial adapter ttyUSB0, it’s a USB device. Remove debug_port, the adapter will be found by OpenOCD through the USB VID/PID and description.

Thanks, that’s it. Its working now. Premium support !
Can I paypal you a beer ?

Good to hear that it’s working now. I don’t have my paypal address in my profile (and also not expecting donations for the regular support I’m doing here anyways), but I sent you a PM if you really want to :smiley:

Could you please explain what do you mean by “disabling the certificates package with the menu”?
I am facing the same problem currently and do not understand how to fix it.

on the left side of VSC, click on the platformio icon. That opens a menu. Also on the left side, look for a sub menu that says run menu config. That starts a script in the output window that shows a config menu.
