rp2040 example outdated

[DASPRiD]

I was trying to work from the rp2040 example, but it seems to be outdated. I tried to adjust it to make it work and adjusted the pins to my board layout, see my diff:

I have a fat32 formatted SD card in the reader (done via gparted). When trying to run the example, I get the following error:

Sorry about that, I forgot to update the example in #30, They'll be fixed soon.

[DASPRiD]

Thanks. Looking at examples/rp2040/src/main.rs, it doesn't seem that you changed anything I didn't change in my diff. Is the error message I see not related to this then?

[CBJamo]

That is correct, that pr only fixes the compile errors in the examples.

The CorruptedFileSystem error you're seeing is probably unrelated. Can you try flashing the sd card with this known-good fat32 image?

[DASPRiD]

I assume I can just dd that onto the /dev/sdX1 device?

[DASPRiD]

Confirmed, that worked. Now the question is why it doesn't work when formatted via gparted…

[DASPRiD]

Okay, figured it out, gonna open a new issue.
