Hi,

i am using a TTGO T8 V1.8 devboard which has an onboard card reader. i installed the newest micropyhton Version on the board.

The Board has on the bottom side following description:
SD
D2=12
D3=13
CMD=15
CLK=14
D0=2
D1=4

i used the following Code to use the SD-Card:

import machine, sdcard, os
from machine import Pin, SPI
spisd = machine.SPI(2, baudrate=10000000, polarity=0, phase=0, sck=machine.Pin(14), miso=machine.Pin(2), mosi=machine.Pin(15))
sd = sdcard.SDCard(spisd, machine.Pin(13))
vfs = os.VfsFat(sd)
os.mount(vfs, "/sd")

When the esp32 starts i get the following error:

WebREPL daemon started on ws://XXX.XXX.XXX.XXX:8266
