Description
I've tried several tutorials, in several different ways, Amazon S3, HttpUpload, SD Card, in all the same error: "Flash Read Failed"
I located the origin in
Update.h
(#define UPDATE_ERROR_READ(3)
Update.cpp
return("Flash Read Failed");)
In this line of code the error:
line 242 Update.cpp
if(!_enablePartition(_partition) || !_partitionIsBootable(_partition)) {
_abort(UPDATE_ERROR_READ);
return false;
}
I've tried all versions arduino-esp32
2.0.0
2.0.1
2.0.2
2.0.3-RC1
There is another strange thing, sometimes, right after erasing the flash and uploading a new file system with OTA, it displays the error message, but when resetting the ESP32-S2 it is up to date.
But from here on, new OTA updates don't work. Uploading via USB doesn't work either, I have to do the disk erase again.
