PN7150 not working

pratyushtomar — Wed, 14 Sep 2016 13:29:42 GMT

I am using Raspberry pi os image provided by NXP (with PN7150 drivers and library pre built) for testing PN7150 NFC. I tried using nfcDemoApp but PN7150 doesn't respond. I am able to detect it's address 0x28 when I run i2cdetect command. Following is the log while running nfcDemoApp

./nfcDemoApp poll

Hi Pratyush Tomar,

Would you please specify the Raspberry Pi rev info? Maybe I can try to reproduce it on my side.

Thanks for your patience!

Have a great day,
Kan Li

The problem was with our NFC board. Thanks for the reply.

Hello Pratyush Tomar,

I have the same problem but I cannot log anything on the demoboard. What was your issue?

I cannot launch the demoboard, the adresse is even 0x28. I'm locked in the polling process juste under the

"... press enter to quit ..." message. The board do nothing.

Could you help me please,

Kind regards,

Olivier

Mine problem was with it's NFC antenna and I was not using demo board but self designed NFC board using PN7150 controller.

We sort off have the same problem. The NCI_CORE_RESET command is acknowledged but no response is send by the PN7150. The power seems fine and everything is decoupled as stated in the hardware design reference.

What was the problem with your antenna? Maybe we have sort of the same hardware problem where the CORE hangs due to an unexpected hardware state of some sort. Or a self test during startup failed.

Any idea what the firmware checks during startup / reset which can make it hang? Or maybe end up in an endless reset loop?

Nevermind my post, our problem was probably that we forgot to flush the data cache of the MCU before we started the DMA transfer. So we thought that we send NCI_CORE_RESET but we actually send giberish.

My apologies.

I know this is an old post, but is there any chance you remember what your hardware issue was. I just got a test batch of custom boards I designed and am running into similar errors
