I switched to Platformio after years of developing with Arduino IDE 1.*. I switched because Arduino IDE is very slow with ESP32 development and I just didn’t get my new Banana-Pi BPi-leaf-s3 to upload.
Platformio seems to do it partially(?). It always ends in an unclear error (to me).
Beneath is the terminal output of uploading “blink” to the BPi-leaf-s3, which ends in a stack-trace from esptoolpy without a clear reason. Below the terminal output I have put the platformio.ini and the code.
I run Visual Studio Code 1.67.2 on a Windows 10 laptop.
Can anyone please explain what is going wrong?
UPDATE 1
I changed the MEM_END_ROM_TIMEOUT from 0.05 to 0.2 in loader.py as described here esptool timed out after "Running stub..." - ESP32 Forum, but without any success…
UPDATE 2
I added “upload_flags = --no-stub” to platformio.ini and that fixes the issue (for now), but it seems not to be ideal, as described in the same article: esptool timed out after "Running stub..." - ESP32 Forum
So initial question remains: how to prevent the “StopIteration” in the esptool.
Thanks a lot!
