PN7120 i2c errors read and write

[bryantrilck]

Hi,

I am trying to use PN7120 with Intel Edison and Yocto kernel 3.10.17.

I configured platform data, GPIO and I2C.

When I start ./linux_libnfc-nci/nfcDemoApp poll

Do you have any idea about this errors ?

Hello Bryan,

      According to above logs, I feel there are 2 possibilities for the issue:

(1) Didn't load linux driver of PN7120.

When you configure linux kernel by "make menuconfig" command, did you select it's driver ?

(2) Checking device tree

Check device tree of your board , please ! PN7120 is I2C device, so it should be mounted corresonding I2C bus(such as I2C1/2/3 etc)

    After BSP and linux driver are both loaded correctly, you will find PN7120 device in path /dev/, only the step is finished, DemoAPP can be run successfully.

    Due to no debugging conditions, so we can only give you some advice. Hope above suggestions are able to help you solve the issue.

Regards,

weidong

NO the device namw should be /dev/pn544. it will never be pn7120.
