<![CDATA[[SOLVED]LoPy Bricked, RED LED]]>I had my expansion board working with both until yesterday. I tried with 2 LoPy and the result is the same, however when I put my WiPy it is working fine. I also have an expansion board v1.0 and the result is the same.

I tried to update one of the LoPy's firmware and it is now booting with the LED permanently red. Even in safe boot after being ORANGE it stays RED.
I have been able to connect to my other LoPy with minicom via Linux (and now it is working again via widnows) but the other one seems bricked.
Any idea of what to do ?

Thank you in advance,

Benjamin

Use
python3 esptool.py -.port com_port --baud 230400 --chip esp32 erase_flash
and then update the device again.

And it worked again after several tries.
