I'm trying to run the `embedded-fatfs` RP2040 example (https://github.com/MabezDev/embedded-fatfs/blob/master/examples/rp2040/src/main.rs) but it's failing at different points with different SD card. With one 256MB SD card (yes they still exist) I'm getting this
```

```
With another one (32GB) I get an endless `Failed to init card, retrying...`. Both cards are FAT formatted and work fine on my computer. Any ideas what could be the problem?
