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

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?
