Continue get LPCD event from NCX3321

Hi NXP team,

My team built a NFC demo board with S32K146 & NCX3321. We got an error message when calling "phhalHw_Lpcd" function. We traced FW behavior and found it was failed in "phhalHw_Ncx3321_Int_EventWait" with "PH_ERR_INTERNAL_ERROR". We also printed "pEvtPayload" as bellow.

EvtPayLoad [3 - 0] : <Firs time> 0X 00 00 06 3B ; <Later> 0X 00 00 00 8c / 0X 00 00 00 8d / 0X 00 00 00 8f

EvtPayLoad [7 - 4] : 0X 00 00 00 23

We found EvtPayLoad [3 - 0] will be a little different but EvtPayLoad [7 - 4] is always the value.

Please tell us why this function keeps reporting errors.

Thanks a lot.

Hello @yu_vincentcy

NCX3321 is an automotive product. All of design resources are security files, so we cannot see this part of the project code. It's recommanded that you contact your local FAE of NXP and get the support. If you don't know who your FAE is, please let me know, and I'll help establish contact.
