TDA8026 - Card Activation

[thiago_machado]

Hello all. I'm currently working on a Contact Card Interface. The idea is to send APDU's from a i.MX8M microprocessor throught it's USB bus to PN7412, that has a TDA8026 connected to it. I was able to successfully communicate and activate contact cards located at PN main slot, but when I try to replicate the same procedure in a card located at one of the TDA8026 slots (Slot 5), I get a empty ATR vector response, meaning that no activation was done. Here's the steps I followed in order to make it respond.

    phStatus_t eStatus = PH_ERR_FAILED;
#ifdef PHFL_ENABLE_SAM_KEY_STORE
    /* Global instance for  CT pal parameter's structure */
    phhalCt_InitParam_t sInitParams;
    uint8_t gbAtrBuffer[32]={0};
    phpalCt_DataParams_t tDataParams;
	tDataParams.pbAtrBuffer = (uint8_t *)&gbAtrBuffer;
	tDataParams.bSizeOfATRbuffer = 32;

    sInitParams.bAutoCTDeactivationEnable= 0;
    sInitParams.bCardPresConnectorStatus= gpkphCfg_EE_Boot_CT->bConnectorType;
    sInitParams.bPullupSetStatus = gpkphCfg_EE_Boot_CT->bPullUp;
    sInitParams.bSlewRateConfig = gpkphCfg_EE_Boot_CT->bSlewRate;

    phpalCt_Init(&sInitParams);

    do
   {
        tDataParams.pbAtrBuffer = (uint8_t *)&gbAtrBuffer;
        tDataParams.bSizeOfATRbuffer = 32;

       /*Initialize the TDA*/
       eStatus = phhalTda_Init();
       CHECK_SUCCESS(eStatus);

       /*Switch to auxiliary slot, because SAM is will be used from auxiliary slot*/
       phhalCt_SwitchSlot(E_AUXILIARY_SLOT);

       /*Select the Auxiliary slot number*/
       eStatus = phhalTda_SelectSlot((uint32_t)gbTdaSlotNum);

       /*Check the presence of SAM in the selected slot*/
       eStatus = phhalTda_GetStatus(E_PRESENCE);
       if(eStatus != SAM_CARD_PRESENT_IN_SLOT)
       {
           break;
       }

    phpalCt_SetConfig(E_EMV_ENABLE,0);


    /*Activate the SAM card*/
    eStatus =  phhalTda_ActivateCard(&tDataParams);

I'm using DoorAcceessExample_AUX_slot software example provided by NXP and developed by Anish Ahammed in 2016.

Hi! is there any axample/code that initialites any TDA, using GPIO instead of I2C? some TDAs doesnt have an I2C interface. Thanks!

Hello! How to get DoorAcceessExample_AUX_slot example? How I can request it? Where do I need to sign valid NDA?

Hi @thiago_machado ,

Did you make any change in DoorAcceessExample_AUX_slot example? Please kindly clarify.

Have a great day,
Kan
