MIFARE Plus reader

[Serhii]

Hi,

I am developing a MIFARE Plus reader in SL3 mode and I am using the NFC Reader Library, but I can't find information on using the functions from this library in the docstore. I know that there is a description of this library for MIFARE Classic and MIFARE Ultralight (UM10663), is there the same document for MIFARE Plus?

Best regards.

[Serhii]

Thank you for the reply @Kan_Li .
Yes, I have a file (Sw375622), but I don't see an example in it that describes how to read MIFARE Plus, is there an example somewhere that describes a sequence of functions to read MIFARE Plus?

Hello @Serhii ,

The extended version of NFC reader library contains the code for Mifare Plus, and you may request it from NXP doc store. please kindly refer to the following for more details.

Have a great day,
Kan

Hi @Kan_Li I'm looking for the extended version of nfc reader library.

I have high access to "Products -> NFC & Contactless Reader Solutions -> NFC Frontend Solutions", but I only see the public version of the library and I cannot find the sw375622, can you tell me where I can find this file?

[Kan_Li]

Hi @germano ,

The path is "MIFARE ICs > Application Notes > NFC Reader Library", but if you still have this problem, you have to request a higher access right.

Have a great day,
Kan

Hello again @Kan_Li,

I found and built a project which is in the library for MIFARE Classic. It works and I decided to make a MIFARE Plus read based on this example. I added these definitions to my project:

• NXPBUILD__PH_NDA_MFP
• NXPBUILD__PHAL_MFP_SW
• NXPBUILD__PHPAL_I14443P4_SW
• NXPBUILD__PHPAL_I14443P4A_SW

I see that P4 and P4A are activated correctly and then I run the command:

phalMfp_AuthenticateSL3(psalMFP, 1, 0x4000, 0,0, bLenDivInput, pDivInput,bLenPcdCap2, pPcdCap2In, pPcdCap2Out, pPcdCap2);

But I get status 0x0201 - which corresponds to PH_ERR_IO_TIMEOUT, I can't understand why this happens and how I can solve it.

Best regards.

Hello @Serhii ,

Mifare Plus is delivered initially in SL0, have you switched it to SL3 already? You may request the full version of data sheet for mifare plus from NXP doc store for more details regarding this topic.

Have a great day,
Kan

Hi @Kan_Li 

Yes, I have Mifare Plus and it is already converted to SL3. I am wondering why when I send phalMfp_AuthenticateSL3 I get a timeout error, and if I put the wrong key block for this command I get the error that I specified the wrong block, how do I solve this problem?

[Kan_Li]

Hello @Serhii ,

Which NFC reader library are you working on? Is it possible to share your application code for a review?

Have a great day,
Kan

I use the library in the docstore (Sw375622).

        /* Card detected */
        /* Get the tag types detected info */
        status = phacDiscLoop_GetConfig(pDiscLoop, PHAC_DISCLOOP_CONFIG_TECH_DETECTED, &wTagsDetected);

        /* Check for Status */
        if ((status & PH_ERR_MASK) == PH_ERR_SUCCESS)
        {
            /* Check for Type A tag detection */
            if (PHAC_DISCLOOP_CHECK_ANDMASK(wTagsDetected, PHAC_DISCLOOP_POS_BIT_MASK_A))
            {
                /* Check for MIFARE Classic */
            	DEBUG_PRINTF ("\nSAK: 0x%x",pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aSak);

            	if (0x20 == (pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aSak & 0x20))//if (0x08 == (pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aSak & 0x08))
                {

                    DEBUG_PRINTF ("\nUID: ");
                    phApp_Print_Buff(pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aUid,pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].bUidSize);

                    bFirstAuth = 1;
                    wBlockNo = 0x4000;
                    bLenDivInput = 0;
                    bLenPcdCap2 = 0;

                    status = phalMfp_AuthenticateSL3(psalMFP, bFirstAuth, wBlockNo, 1,0, bLenDivInput, pDivInput,0, pPcdCap2In, pPcdCap2Out, pPcdCap2);
                    CHECK_STATUS(status);

                    //TODO Read command

                    DEBUG_PRINTF("\nPlease Remove the Card\n\n");

                    /* Field RESET */
                    status = phhalHw_FieldReset(pHal);
                    CHECK_STATUS(status);

                    /* Make sure that example application is not detecting the same card continuously */
                    do
                    {
                        /* Send WakeUpA */
                        status = phpalI14443p3a_WakeUpA(pDiscLoop->pPal1443p3aDataParams,
                                                        pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aAtqa);

                        /* Check for Status */
                        if (status != PH_ERR_SUCCESS)
                        {
                            break; /* Card Removed, break from the loop */
                        }

                        /* Send HaltA */
                        status = phpalI14443p3a_HaltA(pDiscLoop->pPal1443p3aDataParams);
                        CHECK_STATUS(status);

                        /* Delay - 5 milli seconds*/
                        status = phhalHw_Wait(pDiscLoop->pHalDataParams, PHHAL_HW_TIME_MILLISECONDS, 5);
                        CHECK_STATUS(status);

                    }while(1);
                }
            }
        }

Debug log

Reader chip RC660: 0x1a

Ready to detect

SAK: 0x20
UID: 04 2E 6D 5A 6C 5C 80
Error - (0x0201) has occurred : 0xCCEE CC-Component ID, EE-Error code. Refer-ph_Status.h

Please Remove the Card

I found the following that I am not getting a response from the card:
wOption = 8000
pTxBuffer = 70004000
status = 0 (PH_ERR_SUCCESS)
But next:
wOption = 4000
pTxBuffer = 0
status = 0x0201 (PH_ERR_IO_TIMEOUT)

In other words, I don't get the RndB number from the card

Hello @Serhii ,

Thanks for the sharing! Looks like the SL3 authentication command was not issued at the right state, did you also download the full version of data sheet for Mifare plus? It contains the flow for authentication under SL3. Please kindly refer to the following for details.

Have a great day,
Kan

Hi @Kan_Li,

Thanks for the reply, can you tell me the path to this file because a search on docstore gives no results.

[Kan_Li]

Hello @Serhii ,

The path to this file is "MIFARE ICs > MIFARE Plus > Product Description", but if you still can not find it, you may have to request a higher access right.

Have a great day,
Kan

I have a high level of access, but I don't have this "MIFARE ICs > MIFARE Plus > Product Description" path, I don't have a "MIFARE Plus" section in "MIFARE ICs"

I only have "MIFARE Plus EV2" but it does not have the file you told me.

If such a path exists and the "HIGH" access level is not enough, what do I need to do to raise my access level even higher and get the file I want?

[Kan_Li]

Hello @Serhii ,

From the path of "MIFARE ICs -> MIFARE Plus EV2 -> Product description", you may still find the full version of data sheet, select the category of "Product data sheet" which can also be used as a reference.

Hope that helps,

Have a great day,
Kan

I can ask you to send me this file (Ds163735) by private message. I have a signed NDA. Because reading "Ds522332 - MF1 P(H)X2 - MIFARE Plus EV2 (3.2)" that you told me about does not give me full understanding of what I am doing wrong. I have the Level 3 and Level 4 protocol activation successfully activated, but I cannot authenticate to SL3 to gain access to read the card.

[Kan_Li]

Hello @Serhii ,

I just replied your private message.

Have a great day,
Kan

Have the same problem - can't find Ds163735 document (only ds522332).

[Kan_Li]

Hi @Viktor_ ,

You have to sign NDA at first and then request a higher access right from the doc store.

Have a great day,

I have already signed the NDA.

And have "High" access rights (full access) on docstore. See the attached files.
