|
|
|
|
1 byte = 0xb4 -- signature
|
|
4 bytes -- firmware name length (big endian)
|
|
6 bytes -- versioning info ( byte 4 is format version )
|
|
N-6 bytes -- firmware name (zero fill)
|
|
|
|
|
|
PIECE HEADER
|
|
|
|
1 byte = 0x54 -- piece signature
|
|
6 bytes -- unknown
|
|
2 bytes -- checksum for the piece contents (xorpair)
|
|
12 bytes -- piece name (first byte is FF if is the last)
|
|
4 bytes -- piece size (big endian)
|
|
4 bytes -- unknown
|
|
block {
|
|
1 byte -- if (value '1'-'9') { ..there's a comment.. }
|
|
1 byte -- length of comment
|
|
N bytes -- comment
|
|
}
|
