I need to hook up an SD card to a CoreInk unit using MicroPython. I have tried code that works perfectly with an ESP32 WROVER, as well as code from the boot.py file from an M5stack-CORE, but nothing works on the CoreInk. For example, the code:
import machine, os
sd = machine.SDCard(slot=3, miso=34, mosi=23, sck=18, cs=14)
sd.info()
os.mount(sd, '/sd')
gives the error:
OSError: (110, 'ESP_ERR_TIMEOUT')
