ESP32S3 Problem uploading after selecting the wrong board type.

[frippe75]

Hi,

Uploading via USB worked just fine. I think I messed up by programming one of the eFuses "unintentionally".

I have been struggling a little with my customboard where I'm having issues with GPIO pins 4-10 in general.
Since I didn't create a custom board definitions file I went with the Lolin S3-mini since it's the "same module". ESP32S3-mini-1-N8. but as a non-module.

Boot now looks like

Code: Select all

I cant get out of this situation. I both have the USB and an FTDI option on this board thinking it would be good if I messed up.
But I cant get the into "downloading mode" ...

I think I messed up by programming one of the eFuses

Well, did you or didn't you program any eFuse?

Have you tried manually pulling IO0 low before power up?

Yes normal way of getting into download mode has been tried. I don't have any PSRAM on my board and I don't think there is any on the esp32s3-mini-1-n8
