I try some cheap SD card on ESP8266 (Micropython) appear error below when via

Code: Select all

spi = SPI(1, sck = Pin(14), mosi = Pin(13), miso = Pin(12))
sd = sdcard.SDCard(spi, Pin(15))
uos.mount(sd, '/sd')

Code: Select all

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "sdcard.py", line 234, in readblocks
OSError: [Errno 5] EIO

Others works fine.
and all works fine on PC (Windows), included the not compatible ESP8266 (Micropython) parts.

I want to find out the differences between works fine parts and not compatible parts. and modify some code let them works.
