i would assume that it is caused by the following issue: https://github.com/AndiDittrich/NodeMCU-Tool/blob/master/docs/Reset_on_Connect.md

I have the very same problem, and the solution on the documentation did not work for me... Even tried with 5000 delay.

gpr-indevelopment commented 3 years ago

Actually, the command I was trying to run is not fsinfo. I was getting the error on mkfs. It worked for me when running fsinfo before mkfs using the recommended connection delay. Thank you @AndiDittrich

weskerfoot commented 3 years ago

I had the same issue, and some combination of these things helped fix it for me:

1) Hold down "flash" button, and "reset" button at the same time. 2) Release the "reset" button 3) Reflash firmware using esptool (while still holding the "flash" button) 4) Reset 5) Reflash again 6) Uploading works again.

I'm not sure what happened exactly, but this worked for me.
