… aren’t that easy anymore. Because NAND flash can contain bad sectors, everything is getting a bit more complex. We introduced a special format called “nfi”, which contains a header (and possibly a CRC) and 3 different partitions: (loader, boot, root).
You can flash this either with the bootloader directly (using a special HTTP client or using a browser), or using a special version of Dreamup.

If you don’t have a network or trashed your second stage loader, you can flash using only a serial cable.
