Hello Everyone,

I am using PN7150 sbc with ncfDemoApp, that we are using with beagle bone black.
Here's the details of compilation.
Linux kernel version: 4.14.49-ti-r54
Gcc version: 6.3.0
I have used  --enable-alt & --enable-pn7150 options while configuration.
I have downloaded the latest code from git  as mentioned in the document AN11697 PN71xx Linux Software guide.
At present the tag is not getting detected by the sbc.

Here's the output of the previous NfcFactoryTestApp, which runs without errors.
