I have upgraded to version 1.23.0 to 1.24.0 encountering the error when mounting SDCard. The sample code in the previous version works without problem, but in the new version of micropython it generates error:

Traceback (most recent call last):
  File "<stdin>", line 5, in <module>
OSError: [Errno 5] EIO

Here's the code I'm using:

import machine, os, vfs

# Slot 2 uses pins sck=18, cs=5, miso=19, mosi=23
sd = machine.SDCard(slot=2)
vfs.mount(sd, '/sd') # mount

print(os.listdir('/sd'))    # list directory contents

This code works perfectly in version 1.23.0
