Raspberry Compute Module PN1750

[pegasussolution]

Hello,

I am using a Raspberry Pi Compute Module 3 (Compute Module IO Board V3.0) with a PN7150 board. The connections I use are the following:

Raspi CM                PN7150

PIN 0 (SDA0)    --> SDA

PIN 1 (SCL0)    --> SCL

PIN 4                --> IRQ

PIN5                 --> VEN

PIN GND           --> GND

PIN 5V              --> 5V

PIN 3V              --> 3V

I've checked if it is detected and is OK, (i2cdetect -y 0) is detected in the address 0x28.

To configure the PN7150 I've done the following actions:

- sudo git clone https://github.com/NXPNFCLinux/linux_libnfc-nci.git

- sudo ./bootstrap

- sudo ./configure --enable-pn7150

- sudo make

- sudo make install

The problem is that when I execute "sudo ./nfcDemoApp poll", I get the following error:

SNEP Client Register Callback Failed

Leaving ...

Can somebody help me with that? I would really appreciate it.

Thanks in advance,

Manuel.

Hi!

The link to Github issue is dead. I think the repository has now "Issues" disabled. Do you have the solution description somewhere else?

Thanks jimmychan, I have followed the steps and it's ok. I have modified the phTmlNfc_alt.h file with my pin definition and the nfcDemoApp runs correctly.
