Raspberry Pi 0W with PN7150: nfcDemoApp says "NfcService Init Failed Leaving ..." when run on provided image.

[brandonjohn]

I have used the provided Raspberry Pi image with a Raspberry Pi 3 and the PN7150 development board (OM5578) to successfully communicate with the PN7150. However, when I run the exact same code (even the same SD card) on the Raspberry Pi 0W, I get the following error:

"Nfc Service Init Failed

Leaving ... "

I have used "i2cdetect" and can confirm that I can communicate with the PN7150, and I can see the communication on a scope. However, when I run nfcDemoApp, there is no communication on the I2C bus (or any other bus for that matter).

Is there a known incompatibility with the Raspberry Pi 0W, or some more information that I can find to help solve this issue?

Thanks,

Brandon

Hello Brandon, Have you got any good solutions to the problem?  Do you know PN7150 development board (OM5578) is compatible with Raspberry Pi 0W or not? brandonjohn

I assume Raspberry Pi zero uses dedicated kernel (probably part of the Raspbian image) but for which the pn5xx_i2c kernel module was not inserted when building the demo image.

What is your email address? I may send you further information if you want to debug it by yourself.
