Swiss won't load
If Swiss will not start, change one thing at a time. Do not reflash firmware or open the console until you have ruled out the SD card and file, which cause most of these failures.
Swiss will not load
Swiss is the loader almost everything depends on, so when it fails to start the whole setup stalls. The cause is nearly always the card, the file, or the entry point, not the console.
- Check the card: confirm the SD card is FAT32 formatted, ideally with a 32 KB cluster size, and reseat it firmly in the adapter.
- Verify the file: make sure the Swiss executable is intact and on the card. Re-copy a fresh known-good build if in doubt.
- Test the adapter: a flaky SD2SP2 or SD Gecko can fail to read. Try a different adapter or a different known-good card.
- Confirm the entry point: if using PicoBoot, ensure it is configured to launch Swiss; if using a boot disc, verify the disc reads.
- Reduce variables: try a small, cleanly formatted card with only Swiss on it to isolate the problem.
Frequent causes
- Card formatted as exFAT or NTFS instead of FAT32.
- Corrupt or partial Swiss copy from a bad transfer.
- A large or fast card the old hardware struggles to read.
Keep a backup loader
Store a second tested Swiss build on a separate card so you can always boot something while you debug.
