PN7150: NxpNci_HostTransceive fails for RF conf

arnoutdiels · ‎04-18-2018

Hi,

We are running into a strange issue with the PN7150.

We are using the NXP-NCI LPC824X example on an OM5578 kit.

This used to work fine, until at some point, the initialization started failing. at this point:

Inside of NxpNci_ConfigureSettings, the RF config transaction seems to return something the code does not expect. The result is on the console "Error: cannot configure NXPNCI settings".

Strangely enough, if I modify the code to ignore the error, everything still works. (It can scan and write to RFID tags).

Is this a known issue? Is there anything to make up from the returned data?

Thanks in advance for your reply!

Kind regards,

Arnout

We have this error also, and have tried replacing the "NxpNci_RF_CONF_2ndGen" without luck.

What should we do to fix this ?

Hello,

Please replace NxpNxi_RF_CONF_2ndGen with the following to prevent further issue:

It seems that it could be related to the described in: PN7150 stopped working · Issue #59 · NXPNFCLinux/linux_libnfc-nci · GitHub (issue encountered on Linux, but also reproducible in RTOS/NULLOS environment).

Please ask for the replacement of the board in the following link:

Hope this helps!
