Hi there,

I've been trying really hard to sort out this error with wiring and looking at other forums but just cannot work it out.

This is the error message I get when using sdcard.py:
Traceback (most recent call last):
File "", line 19, in
File "sdcard.py", line 231, in readblocks
OSError: [Errno 5] EIO

And this is the code I am calling it from:
import machine
import sdcard, uos
import time

cs = machine.Pin(13, machine.Pin.OUT)

Intialize SPI peripheral (start with 1 MHz)

spi = machine.SPI(1,
baudrate=1000000,
polarity=0,
phase=0,
bits=8,
firstbit=machine.SPI.MSB,
sck=machine.Pin(14),
mosi=machine.Pin(15),
miso=machine.Pin(12))
sd = sdcard.SDCard(spi, cs)
time.sleep_ms(500)
vfs = uos.VfsFat(sd)
uos.mount(vfs, "/sd")
#uos.mount(sd, '/sd')
time.sleep_ms(500)
print(uos.listdir('/sd'))

If anyone could help that would be appreciated!
