Problem with ESP32-DevKit-LiPo
« on: August 15, 2019, 10:19:11 PM »
Update:
User Error detected:

I used the module upside down, so my oled was connected to 5V and clock instead 3.3V and GND also the SDA and SCL were  on wrong pins ...
one Board survived, one Board and the OLED are broken...
Sorry for posting without really checking my wireing.



I have a problem with ESP32-DevKit-LiPo:
when i flash anny programm with arduino ide 1.8.9 / esp32 core 1.0.2 i get bootloop.
initially i thought its a software problem, but a different olimex lipo and a devboardc from another brand work, at least most of the time.

also with the esp-idf one modul works and the other doesn't (hello world programm)

is it possible the flash is broken? but there is a check after flashing, right? wouldn't that give an error?

i get the following error repeating in idf:
