Problem with SD Card in Pysense

[ghelbig]

I've read all the posts I could fine - they don't seem to be up to date.

>>> import os
>>> from machine import SD
>>> sd=SD()
>>> os.mount(sd,'/sd')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: the requested operation failed
>>> os.mkfs('/sd')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: error while attempting to format /sd

I'm using Samsung 32GB EVO cards. I tried both as-shipped, and gparted/formated FAT32

I have the latest firmware: release='1.7.0.b1'

No joy. Can someone point me in the right direction?

@ghelbig The latest firmware release is 1.18.0.r1. Try to update first. Then try to reset the device after the card was inserted. That help sometimes. If not, try a different, maybe smaller card.
