Flashregion Table[edit | edit source]
Location:
- NOR: 0x0000400 - 0x00007FF
- NAND: 0x0040200 - 0x00407FF
The next 1024 bytes contain the entry table
Header[edit | edit source]
Small 16 byte header to describe length and entry count
example[edit | edit source]
| NOR: 0x0000400 - 0x000040F | NAND: 0x0040200 - 0x004020F |

structure[edit | edit source]
| Address | Length | Value | Description |
|---|---|---|---|
| 0x0 | 0x4 | 0x01 | Unknown |
| 0x4 | 0x4 | 0x0B | Entry Count |
| 0x8 | 0x8 | 0xEFFC00 | Length of Flash Region (relative to 0x400 (region start) |
First is a header, this tells us how many files are stored here.
Entry Table[edit | edit source]
Then follows a 32 byte entry for each file
