PN7642 mifare desfire example not work

cesarP · ‎06-19-2024

Good day

I have the PN7642 dev kit, and I have the example: pnev7642fama_NfcrdlibEx10_MIFAREDESFire_EVx_Freertos_Ecp

In the file NfcrdlibEx10_MIFAREDESFire_EVx.h I remove the comment in the line #109 to select the chip reference #define PN7642EV_C100

I modify the menu to select directly AES Key

Then build and debug and I put in the antenna a mifare desfire EV2 card in blank and I get the error:

Line: 689 Error - (0x2083) has occurred : 0xCCEE CC-Component ID, EE-Error code. Refer-ph_Status.h

Line: 528 Error - (0x2083) has occurred : 0xCCEE CC-Component ID, EE-Error code. Refer-ph_Status.h

Line: 461 Error - (0x2083) has occurred : 0xCCEE CC-Component ID, EE-Error code. Refer-ph_Status.h

I put some rtt messages and I get the following info:

TX: 0A 00 /* Authentication */

RX: AF 35 26 87 2E 8D 76 96 FA

status of operation: 0x0071 /* PH_ERR_SUCCESS_CHAINING */

TX: AF EA B2 1A 6B 49 D0 11 C0 28 24 A2 6F 70 31 48

DB

RX: 00 F8 06 8C 86 FC 27 57 8B

status of operation: 0x0000 /* PHAL_MFDFEVX_RESP_OPERATION_OK */

status of operation: 0x0083 /* PHAL_MFDFEVX_ERR_PERMISSION_DENIED -> MFDFEVx Current configuration/status does not allow the requested command. */

The example fails in the authentication process, I repeat that the cards are new and are blank, I have 5 and with all happens the same, so what would be the cause of a failure in the authentication? I have NDA but I can not find information about desfire EV2, the datasheet published does not mention anything about this, could you help me to check where it fails or where I get information about the protocol desfire EV2?

thanks

Hi @cesarP

I would suggest you run demo pnev7642fama_check_nxpfw_update , update the firmware to the latest version, and try it again.

Since the package you are using is based on NDA, it is better to create a ticket for your further question.

Regards

Daniel
