PN7642 SPI host interface not working with NxPNfcRdlib

Hi there,

I am using SDK_2.x_board_PNEV7642FAMA SDK(2.12.5) and tested the following examples.

- pnev7642fama_NfcrdlibEx2_ECP_Freertos_Ecp

- pnev7642fama_pn76_hostif_spi

I can test both examples without any issue.

I tried to combine both examples so that the credential information can be sent to the host(LPC55S16 board) by the SPI bus.

Here is what I did.

- modified exiting pnev7642fama_NfcrdlibEx2_ECP_Freertos_Ecp example and add a new freeRTOS thread to run the hostif_spi function(from example pnev7642fama_pn76_hostif_spi). Something like this

[CODE]

If I comment out ECP_thread, then LPC55S16 board can send loopback command and receive the response from PN7642 board. As long as I enable ECP_thread, then LPC55S16 board was unable to receive the response from PN7642 but PN7642 was still able to execute ECP functionality properly.

Any insight?!

Thank you very much.
