Catalina and "Timed out waiting for packet header" #502
The FTDI driver didn't work. If I flash the ESP32 I got:
My workaround is "Connect G0 pin to GND".
The CP2104 at M5Stack Core often worked, but sometimes I got the same error and I then I connect G0 pin to GND.
My short test showed the problem:
Can anyone help me to program without connecting G0 pin to GND?
There is a known timing problem with macOS X Catalina and esptool.py. Espressif knows about it. M5Stack knows about it, but doesn't acknowledge it their problem. The (proven, working) workaround entails connecting pin G0 to ground with a short wire or paperclip while using esptool.py.
Edit: I'm sorry, didn't see the original question. This does not answer the original question about how to proceed without connecting G0 to GND.
