SD Import Issue on FiPy

[Marike]

I've noticed that there's new Sequans firmware available so I decided to go through with upgrading firmware. I put the .dup file on the FAT32 formatted SD card, used pymakr to upload the appropriate lib code to the device, and get an error when running sqnsupgrade.run().

It's erroring out on line 87, specifically with sd = SD(). I next try:

from machine import SD
sd = SD()

And get the following output:

>>> from machine import SD
>>> sd = SD()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: the requested operation failed

I get this on firmware 1.17.3.b1 and 1.18.0.r1. Any ideas what's going on?

@marike Sometimes you have to do a hard reset with the SD card inserted to deztect the card. Also not all card brands and sizes work. And finally especially Windows does not format a clean FAT layout with a single partition.
