Error on esptool.py: A fatal error occurred: Invalid head of packet ('\xe0') · Issue #8 · cnlohr/espusb (original) (raw)

I just pulled your latest commit and make the application, it seems that I'm having this issue on my Ubuntu 16.04 machine to burn into my NodeMCU

A fatal error occurred: Invalid head of packet ('\xe0')

I checked the user.cfg and found the issue (for me at least) to be FWBURNFLAGS = -b 1000000 after changing this to FWBURNFLAGS = -b 115200 or ``FWBURNFLAGS = -b 1500000` I can burn into my NodeMCU nicely.

Does FWBURNFLAGS = -b 1000000 work for you?

and saw the esp82xx really great job there!
