[Yaffs] Structure of YAFFS2 spare OOB area

Dear all,

I've performed a nanddump of a YAFFS2 filesystem and would like to know the exact byte / hex structure of the spare OOB area.

I've read the HowYaffsWorks.pdf and viewed the YAFFS2 specification and development notes but i'm still unable to figure out the structure of the OOB area.

The following are hex extracts of the first few spare OOB areas extracted using a hex editor.

19 91 65 5A 15 1C 81 88 9D E2 24 79 C5 84 F5 43
F3 D9 11 4C AF 1F AE 8A 9E 3E FA CD 51 0A 5F 1D
00 00 F2 01 00 00 04 00 00 00 00 08 00 00 DB 2C
E8 F1 16 5F 5C DB 19 32 00 00 00 00 00 00 00 00

54 0C 1A 2F 62 DA 6B D1 D6 AC A8 CF 56 CF FA 43
09 9F 79 FF A8 CF 56 CF FA 43 09 9F 79 FF 5F 1D
00 00 89 01 00 10 0E 01 00 80 88 E6 03 00 D4 B9
63 32 71 3C 16 50 60 88 00 00 00 00 00 00 00 00

0F C8 31 64 71 3C 71 79 3F 72 A8 CF 56 CF FA 43
09 9F 79 FF A8 CF 56 CF FA 43 09 9F 79 FF 5F 1D
00 00 8A 01 00 30 09 01 00 80 00 00 00 00 3A DD
34 66 99 F3 2A DA 2E 48 00 00 00 00 00 00 00 00

Could someone please explicitly list the order of tags within the spare OOB area / point me in the direction of a document which lists it.

Thank you in advance.

Best Regards,

Eugene
