Using TRF7970A in I.MX6 linux platform

Other Parts Discussed in Thread: TRF7970A

We have interfaced the TRF7970A with the SPI on I.MX6. The SS line from the processor is low.

Also I have include the SPI driver trf7970a.c for linux inside drivers/nfc/

Also I have included the files digital_technology.c ,digital_dep.c and digital_core.c ,digital.h for digital protocol stack implementation inside net/nfc.

But i am not able to understand that from User space how can we communicate with the nfc device. We are using tag read/write mode

Also from the kernel what will be its /dev entry??

We are using linux 3.10.17 Yocto kernel on I.MX6 Sabresd linux

Hello,

The neard application layer uses python scripts, which are available in the neardal.git. You can find the available git repositories at the link below. You may also try reaching out to the neard community since this is an open source and community supported project.

Hi Eddie Thanks for your reply

Right now i am having an issue that nfc0 device is not created inside /dev.

Can you explain me how the flow goes from the trf7970a driver to the digital core.

Also is there any socket created for the nfc digital device?
