Flashed with wrong size selected

General
1

I have flashed a brand new ESP32, although binary was for 16MB, and my board is 8MB. Said it flashed successfully, now seems bricked?

cannot reflash…

tried a second device, was able to flash the binary, although ETh was incorrectly enabled, so it won’t run. Cannot flash a second time…!! :confused:

I’ve found that sometimes after a screwed up flash (user error) I have not been able to flash my devices using mos tool.

For some reason I’ve had best success flashing any Arduino program (any sketch that compiles, even empty) then flashing from mos again. Instructions for setting up ESP32 in Arduino.

good luck

Try mos flash --esp-erase-chip.

cool, thx klimbot that was actually something I tried… I’ll try again. I noticed when it did work initially, it fell back to a slower speed, not sure if I can set the speed…

Wasnt able to get mos flash --esp-erase-chip to work

I have a new PCB where I have put the WROOM module on a daughter board with 2.54mm headers, it seems to be struggling with setting it to flash mode, which is just confusing, especially when I’m holding down boot to Gnd

Tried reflowing the cp2102n USB-Serial, seems to have worked… still having issues with auto program… but progress… :slight_smile:
