Hi guys, I am facing a similar issue with using these pins. I have a custom hardware board and I am using GPIO 39 to 42 for SPI GPIO39 SCK GPIO40 MISO GPIO41 MOSI GPIO42 CS After boot, the SPI connected device works for 2 seconds then it just drops. I created an issue here https://www.esp32.com/view...

Hi everyone, I have been experiencing a problem with an SPI bus and I can't figure it out. I am using a custom developed board with the ESP32-S3-WROOM-1 module on it. I have connected to the board an external ADC MCP3204 from Microchip which communicates over SPI with the ESP, pinout: GPIO39 SCK FSP...
