Flash firmware (Image):
DM 7020 HD needs 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.
