OM27160B1HN with SPI interface not working

[Dharmit_m]

I have purchased a PN7160 based Evalution board  OM27160B1HN with SPI support. I have followed the instructions based on this AN12991 document and interfaced it with raspberry pi 4B, But getting a "NfcService init failed" error as shown in attached image. Please guide to solve this issue

Hello @danielchen we have developed our own custom board based on PN7160 with SPI configuration and the board-bring up is successful but still its not detecting any tags. I am attaching the logs for the reference. Awaiting quick response. Thank you

Hi @Dharmit_m 

 I assume you are using 64-bit OS.  please apply the patch as attached. and try it again.

If you have other issues, please enable all logs and share log with us.

Hi @Dharmit_m 

Please check the configuration file   libnfc-nxp.conf

Find the attached log file as requested. Kindly guide the further step to test the nfc reader.

Thanks

Hi

From your log message,  you can see you are using I2C , not SPI. I would suggest you check it.

Daniel

[Dharmit_m]

as shown in the same log it is trying to initialize SPI at dev/spidev0.0 and setting nxp transport at 0x03 which is SPI as per libnfc-nxp.conf file settings and also the physical hardware interface is SPI only and the Evalution board is OM27160B1HN which is SPI configured during chip manufacturing. please  provide the reference log with SPI if it is working properly to narrow down the issue.

Hi @Dharmit_m 

Are you using the integrated driver or nxp driver?  can you share the configuration file ?

Regards

Daniel

[Dharmit_m]

@danielchen here is the attached libnfc-nxp.conf file.

Hi @Dharmit_m 

Can you try to run NfcFactoryTest application?

Did you enabled the SPI in raspberry PI config?

I have been trying to interface the same PN7160 module with imx93evk, but somehow getting the same error message. " Error in I2C Write".
Why is it reporting I2C write when I am using SPI ?
I am using /dev/nxpnfc. My configs are as follows:-

NXPLOG_EXTNS_LOGLEVEL=0x03
NXPLOG_NCIHAL_LOGLEVEL=0x03

Got to know that the Nfcc Transport is common code for both nxpnfc I2C and SPI driver so that answers my question "Why is it reporting I2C write when I am using SPI ?"

However the issue is still there. Getting Write errors.

@danielchen here is a attached screenshot containing factory test application log, and spi configuration of raspberry pi.

 @Dharmit_m, is it working for you now ?
