Hello everybody,
I am interfacing SLE4442. I can read all its memory. I am having problem in verifying PSC. i have implemented the following algorithm:
1] read secured memory (0x31,0x00,0x00).
data read: (0x07,0x00,0x00,0x00)
2] update secured memory (0x39,0x00,0x06).
3] compare verification data (0x33,0x01,0xFF)
4] compare verification data (0x33,0x02,0xFF)
5] compare verification data (0x33,0x03,0xFF)
6] udate secured memory (0x39,0x00,0xFF)
7] read secured memory (0x31,0x00,0x00).
data read: (0x06,0x00,0x00,0x00)

As you can see it is not verifying. if anybody can help, then pls reply.

Thanking you,
ameya parab
