Hi @Taimoor852,

Thank you for reporting this. Please try right click on Project > C/C++ Index > Rebuild it should reduce the number of indexer errors. Also, it's unfortunately common behavior on ESP-IDF 5.0 and higher to have some unresolved error with some imports, check this while we work on a fix.

Hi @sigmaaa Thanks for the reply. i will try as you mentioned in above and let you know.

one more thing i wanted to make clear, while ESP-IDF Configuration, i have seen something in the console Configuration.Unable to copy rules for OpenOCD to system directory, try running the eclipse with sudo command please let me know if that will cause some problems ?

Hi @Taimoor852,

contrib/60-openocd.rules file is needed for USB devices on GNU/Linux, so theoretically you can have some problems with debugging using openocd. So I guess try running Eclipse with the sudo command or copy this file https://github.com/espressif/openocd-esp32/blob/master/contrib/60-openocd.rules to /etc/udev/rules.d/ manually
