3This tool composes a firmware file, out of:
41. Template for the first Flash page
52. Bootloader
63. Archos image
74. Rockbox image
8
9Use with extreme caution, the components have to match!
10The aspects are:
11- Model (Player, Recorder, FM, V2)
12- boot type (standard boot ROM or ROMless)
13
14Such a firmware file can then be programmed with "firmware_flash.rock".

3MiniMon is the tiny but powerful-enough piece of code that can be loaded
4with the UART boot mod.
5It allows to read and write memory, flash program, execute code.
6This is suitable to reflash the box, load Rockbox or the gdb stub, etc.

3This is the client side for MiniMon, a command line program that communicates with it.
4It can be used to reflash a box from ground up, load a program like gdb stub or Rockbox,
5and other diagnostics.
6
7Current implementation is for Windows, but with a different UART implementation
8it should work for other platforms (Linux) as well.
