SDSPI and ESP32S3 pinout
Posted: Sat Sep 16, 2023 5:31 pm
Hello,
I'm trying to use an SD card reader in SPI mode. To get familiar, I used the SDSPI example. I have no difficulty with the ESP-WROVER-KIT development board and the default pin configuration. I then migrated to a LiliGO T-DISPLAY board with ESP32-S3 (without display installed). I rebuilt the application for ESP32S3 target. On the other hand, I used non-standard pins: GPIO_NUM_10 for CS, GPIO_NUM_11 for SCLK, GPIO_NUM_12 for MOSI and GPIO_NUM_13 for MISO. I installed 10K resistors between each of these pins and the 3.3v. As a result it doesn't work. Do you have any ideas to help me resolve this issue? Here is monitor log:
