Its Flash has the following structure:
/dev/fla contains the whole flash. In the following order:
00000000-000003FF something which "file" identifies as
linux-kernel. contains a valid partition-table, 1kB.
00000400-000020FB The bootloader. It can decompress the compressed
part of the filesystems. ca. 8kb.
000020FC-000043FF Empty. 0x00, ca. 8kb. Seems to belong to
00004400-000103FF Writeable area. is 48 kb. filesystem unknown
but looks primitive. two utilities (each 7kb)
in /bin know how to handle that.
00010400... Compressed and readonly. Contains:
/dev/igf1 /-filesystem. ext2, 20 MB
/dev/igf2 /usr-filesystem, ext2
/dev/igf3 /usr3-filesystem, ext2
looks like it's realised with some kind of a loop-mount
filesystem (probably called cromfs) which decompresses on
the fly. I tried with cramfs, but either this isn't the same
or more likely, I haven't found the right start of the file.
(Doh, 15kbit executable, seems possible with objdump...)
