Me No Dev

yes it can

Have you changed anything between 2 layer and 4 layer board? Have you tried entering download mode manually? I do not see IO0 being pulled up?

Do you have a pullup on IO0? And 10uF cap on IO0 or EN is a bit too much. 100nF is enough. 10K pullup is also OK

Issue is in the `TFT_eSPI` library that is not yet compatible with Arduino v3. Please @Patsjemoe go file an issue there (or chime in one already opened by someone else)

Can you try instead of `Wire.begin(21,22,100000);` to have ```cpp Wire.setPins(21, 22); Wire.begin(); ```

The following code works for me on 3.1.1 ```cpp #include "Wire.h" void setup() { Serial.begin(115200); Wire.setPins(6, 7); Wire.begin(); } void loop() { byte error, address; int nDevices = 0; delay(5000);...

requires minimal sketch that we can compile to reproduce.

@Jason2866 please have a look at the 3 styling errors here: https://github.com/espressif/arduino-esp32/actions/runs/9990222877/job/27610471049?pr=10045#step:4:437

CLA is PITA sometimes. The Pre-commit check is waiting for "Pending Merge" label (we add it once we have agreed it's good to merge)

Seems there is a missing code. Please provide a minimal compilable example sketch to reproduce
