I.MX6 DualLite with NFC PN544 on imx-3.14.28-1.0.1_patch

[kunyichen]

Hi

     I work on IMX6DL SABRESD with NXP PN544,

BSP use Yocto L3.14.28-1.0.1_patch release

currently want know how to testing PN544 with tag,

I use the following step, but always can not get a correct result.

Would have anyone give something tips?

Hi KunYi

I am not aware of i.MX6 BPSs nfc support, but it may be added following next links

linux-2.6-imx.git - Freescale i.MX Linux Tree

AN11697  Linux Software Stack Integration Guidelines

http://www.nxp.com/documents/application_note/AN11697.pdf

Best regards

Hi Igor,

    First thank for your reply

    Currently the BSP should support PN544, 

    Yocto/L3.14.28 support "neard" project and linux mainstream support nfc into net interface now

    You can review my attached file and steps, the PN544 I2C/HCI driver has built-in into kernel

    But I'll try AN1167 note! but I know mainstream has accept neard project and integration into kernel tree

[kunyichen]

okay, I have been testing AN1167, still failed

I think the appnote AN1167 should be just support PN7120, due to the library just support NCI interface, not support ETSI/HCI

[igorpadykov]

unfortunately I am not aware of PN7120 drivers for i.MX6, in general

NXP has service for porting drivers : NXP Professional Services:
