Now it's getting very strange. I wanted to test the pins themselves, so I used the following "blinky" code and tested with a multimeter. Pin 36 fluctuates between 3.3V and 2.4V, and pin 37 fluctuates between 0.5V and 0.8V, and pin 35 correctly fluctuates between 3.3 and 0. Why could this be? void se...

EDIT: I managed to get verbose debugging, and the logs in setup() above actually go to the serial monitor now. SPI->transfer definitely doesn't create any logs that I can see

Thanks so much for the reply. Being new to ESP32 programming in Arduino, I have tried very hard to enable verbose logging, referencing this link (https://esp32.com/viewtopic.php?t=5730) but I have had no luck (INO below). Am I missing something? I tried adding the following to my SPI setup: mySPI->b...

Hi, I have a custom PCB with the S3 Mini and an EEPROM chip (very basic schematics for your reference). The code (modified from a git repo I found, also attached) worked with a Wrover Dev kit + breadboard, but for the PCB, EEPROM read operations always give "0" even after writing (see the two sectio...
