Use the following steps to build a project for another architecture:

Move into the project folder and do a cleanup:

idf.py fullclean

Make a backup of the project folder

cd ..
cp -r LCR-meter/ LCR-meter-backup

Move into the project folder and change the architecture:

cd LCR-meter
idf.py set-target esp32c3

Setup project configuration When setting the target several project settings are returned to defaults. Use idf.py menuconfig to check and change settings:

idf.py menuconfig

Change partition settings to: "Custom partition table CSV"
Enable ESP-TLS Server
Enable ESP_HTTPS_SERVER component
Change Serial Flasher config: Flash size (2 MB)  ---> 4 MB
Change HTTP Server: Max HTTP Request Header Length 512 --> 1014

Rebuild the project

idf.py build

Check the USB port used by the new board, by running the following command and (un)plugging the USB connector:

sudo udevadm monitor -u

Further we assume that port /dev/ttyUSB0 is being used: Do a full flash:

idf.py -p /dev/ttyUSB0 flash
