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.

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:

Hi,

I am trying to use an SD Card with the ESP32-S3-WROOM-1-N16 on a custom PCB - ATTACHED Schematics below.

I have tried both the SD.h library and the SdFat.h.
PIN CONFIGURATION:
VSPI_MISO 40
VSPI_MOSI 41
VSPI_SCLK 39
VSPI_SS 38

f_mount failed: (3) The physical drive cannot work
