PN5190 Development Board Unable to Communicate with External MCU

Hello NXP Community,

I am currently working with a PN5190 Development Board and facing an issue while trying to establish communication between an external MCU and the onboard PN5190.

As per the documentation, I have already performed the R5 to R7 resistor replacement, which is required for external MCU interfacing. However, even after this modification, I am unable to establish communication between the external MCU and the PN5190.

Could someone from NXP or the community please advise:

  1. If any additional hardware or jumper configuration is needed for external MCU communication.

Thank you in advance for your assistance.

Best regards,

PN5190
