Flash:Flashregion Table

Flashregion Table

Location:

• NOR: 0x0000400 - 0x00007FF
• NAND: 0x0040200 - 0x00407FF

The next 1024 bytes contain the entry table

Header

Small 16 byte header to describe length and entry count

example

NOR: 0x0000400 - 0x000040F	NAND: 0x0040200 - 0x004020F

structure

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

Then follows a 32 byte entry for each file (typical asecure_loader, eEID, cISD, cCSD, trvk_prg0, trvk_prg1, trvk_pkg0, trvk_pkg1, ros0, ros1, cvtrm)
