A fatal error occurred: MD5 of file does not match data in flash!
-
I purchased an M5Stack Fire and it worked great for about twenty minutes. (using Win10 and Arduino)
Since then I get the error; A fatal error occurred: MD5 of file does not match data in flash!
I've spent an insane amount of time trying to find a fix. Do I just have broken hardware?
Please help.

@pchidley then...Please try these way.
- Turn upside down cable connection.
- Change cable If you have an another cable.

esptool --port <YOUR PORT> write_flash_status --non-volatile 0
or
esptool.py --port <YOUR PORT> write_flash_status --non-volatile 0

Thanks this is the way to go with my M5Stack, got it new and I was never able to make it work, this command fixed it!
Great! Thanks

sorry for resurrecting this post from the dead but where exactly do you run the esptool --port <YOUR PORT> write_flash_status --non-volatile 0 command?

You run this in a terminal or command line program.
Replace YOUR PORT with the name of the port that appears in arduino. On windows this may be COM followed by a number on OSX this is often somelike USBslab.
