Please insert disk into usb drive error after installing picomemcard software on picomemcard +

[D3iv]

I've tried solving this problem myself to no avail, couldn't find anything on the internet regarding this issue. Checked all of my solderjoints, perhaps I'm missing a library or a driver of some sorts?

A few problems come to my mind... Have you connected the SPI SD card module correcly? The SD card is formatted in FAT32?

Same problem here on rp2040-zero, microsd formatted correctly, recompiled with develop pico-sdk. I'm using this microsd module with the AMS1117 regulator bypassed and connected to the 3.3v pin of the rp2040-zero.

To me it seems like your setup is correct.
You have included the fix mentioned in raspberrypi/pico-sdk#1304 correct?
Maybe you could try to swap the microsd module for a different one just to make sure that it's not faulty.
