RP2040-Zero not recognized as a storage device (Windows 11)

[Manghao]

Hello, I have an RP2040-Zero, I transferred the file PicoMemcard+RP2040-Zero.uf2 on it by pressing well on the BOOT button before connecting it to the PC, I have the notification sound windows which dismounts and remounts the USB device, but I do not have access to the storage of the RP2040. I do have PicoTM Mass Storage USB Device

I have the same problem on MacOS, the RP2040 disconnects with an ejection error, although it is present but not displayed in storage.

3 things you should check:

• is the SPI sd module installed correclty (wires and connections)?
• is the microsd card inserted?
• is the microsd card formatted in FAT32 (only format currently supported)?

It seems an issue on the pico SDK, the fix should be this: https://github.com/raspberrypi/pico-sdk/issues/1304

Thanks for the info @carmax91. The related PR is not merged yet but I'll patch it myself for the next release at least until it gets merged.

Is there a manual way I can work around this issue?
