the error:

[nopnop2002]

I was able to build this version.

Code: Select all

$ idf.py --version
ESP-IDF v5.3.2-1-g9a6aba7401-dirty

Code: Select all

$ idf.py build


Project build complete. To flash, run:
 idf.py flash
or
 idf.py -p PORT flash
or
 python -m esptool --chip esp32 -b 460800 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size 2MB --flash_freq 40m 0x1000 build/bootloader/bootloader.bin 0x8000 build/partition_table/partition-table.bin 0x10000 build/esp32_nat_router.bin
or from the "/home/nop/esp32_nat_router/build" directory
 python -m esptool --chip esp32 -b 460800 --before default_reset --after hard_reset write_flash "@flash_args"
