GKI_getbuf() unable to allocate buffer!!!!

[Felix-88]

Hi Team,

I used the PN557 NFC chip to conduct cards reading stress test on Android 8.0. 

After a period of time, the NFC process was stuck and could not read any cards.

Check the log prompts as follows.

02-15 08:47:51.542249 9416 9443 E BrcmNfcNfa: nfc_main_hal_data_cback (): No buffer

How can I solve this problem?

Best regards,
Felix

Hello sir,

My apologies for the late response, at first glance I cannot provide any recommendation without more information. Could you please provide more information regarding your configuration? Also, we would recommend evaluating the possibility of using PN7150 for better hardware support.

Which Host device are you using?

Also, it would be very helpful if you could please let me know if you are using our latest NFC stack. Finally, could you please show us the full log?

Thank you for addressing us.
