Hi,

I can successfully authenticate with KeyA with mifare classic using :

                            status = phalMfc_Authenticate( &salMFC, TARGET_OPERATION_BLOCK,                                           PHHAL_HW_MFC_KEYA, 1, 0, bUid, bUidSize);

but When I want to do this with PHHAL_HW_MFC_KEYB, It failed.

Is there any other prerequisite step needed for using Key B?

Honestly I think using Key B in mifare classic is a common requirement and it's a little weird no one else did not asked it before "how to use mifare classic Key B in NXP NFC Library"? And even no one from NXP support team did not have interest to answer it.
