TDA8026 - Card Activation

thiago_machado — Wed, 12 May 2021 19:42:43 GMT

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 @thiago_machado ,

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

Have a great day,
Kan

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

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