Hello,

I wanted to setup my debug environment in OpenSUSE Tumbleweed, I successfully installed esp-idf and when I ran

idf.py openocd

I got it listening for the GDB server

Code: Select all

mac@localhost:/mnt/sec-vol/workspace-esp/blink> idf.py openocd
Executing action: openocd
Note: OpenOCD cfg not found (via env variable OPENOCD_COMMANDS nor as a --openocd-commands argument)
OpenOCD arguments default to: "-f board/esp32-wrover-kit-3.3v.cfg"
OpenOCD started as a background task 3744

However when I tried running

Code: Select all

idf.py gdb

I got problem with the python site packages

Code: Select all

mac@localhost:/mnt/sec-vol/workspace-esp/blink> idf.py gdb
Executing action: gdb
ImportError: No module named site

So I checked where the bin is sourcing from, I got

Code: Select all

mac@localhost:/mnt/sec-vol/workspace-esp/blink> which xtensa-esp32-elf-gdb
${HOME}/.espressif/tools/xtensa-esp32-elf/esp-2021r2-patch5-8.4.0/xtensa-esp32-elf/bin/xtensa-esp32-elf-gdb

I would like to understand what causing this issue, anyone came across this situation?

The problem is caused by missing Python 2 in OpenSUSE Thumbleweed.
There is no Python 2 package for the distribution anymore.

The issue was fixed in ESP-IDF master branch, but was not backported yet to 4.x: https://github.com/espressif/esp-idf/is ... 1261435018
The new solution is using Python 3

Please try to use ESP-IDF from the master branch to run the debugger.
