How MIFARE Uses Cookies

[Vladimir Knezevic]

Hi,

Thanks for the response.
The problem was not with the FIFO buffer but with the datasheet as it seems. In the PN512 datasheet, section 20. Errata sheet, the selftest answer is not correct. It seems that during copying of the data, two lines were copied twice and then instead of a 64B answer there is a 80B answer with 16B that are repeated (bytes 48-63). Here is the data from the datasheet:
00h, AAh, E3h, 29h, 0Ch, 10h, 29zhh, 6Bh,
76h, 8Dh, AFh, 4Bh, A2h, DAh, 76h, 99h
C7h, 5Eh, 24h, 69h, D2h, BAh, FAh, BCh
3Eh, DAh, 96h, B5h, F5h, 94h, B0h, 3Ah
4Eh, C3h, 9Dh, 94h, 76h, 4Ch, EAh, 5Eh
38h, 10h, 8Fh, 2Dh, 21h, 4Bh, 52h, BFh
4Eh, C3h, 9Dh, 94h, 76h, 4Ch, EAh, 5Eh
38h, 10h, 8Fh, 2Dh, 21h, 4Bh, 52h, BFh
FBh, F4h, 19h, 94h, 82h, 5Ah, 72h, 9Dh
BAh, 0Dh, 1Fh, 17h, 56h, 22h, B9h, 08h.
