ESP32-S2 build problems

[MarkusR]

Hi,

I tried to follow the steps for setting up the esp32-s2 toolchain for the esp32-s2-wroom module however it doesn't really work.

I'm following those steps:
https://docs.espressif.com/projects/esp ... -configure

$ cd /Users/markus/devel/esp32/esp-idf/examples/get-started/blink
$ idf.py set-target esp32s2
$ idf.py menuconfig

sdkconfig shows up:

CONFIG_IDF_CMAKE=y
CONFIG_IDF_TARGET_ARCH_XTENSA=y
CONFIG_IDF_TARGET="esp32s2"
CONFIG_IDF_TARGET_ESP32S2=y
CONFIG_IDF_FIRMWARE_CHIP_ID=0x0002
....


$ make
make

Any idea what I can do next?

Hi Markus,

The ESP-IDF "GNU Make" build system doesn't support ESP32-S2, unfortunately. Try using "idf.py build" to build, instead of "make".

(It is possible to run CMake with arguments to then run "make" as the build step for ESP32-S2, but "idf.py build" takes care of this part automatically.)

I just figured that out 10 minutes ago .. yes it needs idf.py build it fixed the problem

thanks for your quick reply!
