Flashing in Yamon
1. The dumped flash file contains both boot loaders in the first
&H80000 bytes. Use your favourite HEX-editor to delete these
bytes. I use the free software Frhed for this.
2. Select the first byte and then shift-select the byte on position
0x7ffff. Notice that the next bytes show “-rom1fs-“ which is the
label of the kernel!
3. Press the DEL-key to delete the selected bytes. Confirm that
you are deleting x0 to x7ffff.
4. Save the resulting bytes into a new file.
5. You will obtain a new file with exactly 7.864.320 bytes. It
contains the complete flash image except the two boot loaders.
6. This file can be written directly from within YAMON to the
flash chip using the “pflash” command. Make sure that the file is
loaded into &Hb0100000 and its size is &H780000. This makes the
recovery process much faster, as you do not have to start Linux
from RAM and then transfer files using FTP.
