nRF5340 NFC and TAG4 library

[mnvcsUDT]

Hi Everyone,

Wanted to test the NFC library provided by the nrfxlib on the nrf5340DK. Added the following config file:

CONFIG_NET_IPV6_MLD=n
CONFIG_NET_IPV6_NBR_CACHE=n
CONFIG_NET_IPV6_RA_RDNSS=n
CONFIG_NET_IP_ADDR_CHECK=n
CONFIG_NET_UDP=n

Resulted in:

gen_isr_tables.py: error: multiple registrations at table_index 17 for irq 17 (0x11)
Existing handler 0x5749, new handler 0xa379
Has IRQ_CONNECT or IRQ_DIRECT_CONNECT accidentally been invoked on the same irq multiple times?

How could I check the reason for collision? nrf sdk version is 1.7.0.

Hello,

Where does the errors come from? (The lines below "Resulted in:"? It looks like a python error, so does it come when you try to compile the application? I tried to compile a sample using your prj.conf file, but it doesn't give the same error as you get (it complains about some zboss handlers). Can you upload the entire project, so that I can try to replicate the error you are seeing?

Best regards,

Edvin

Hi Edvin,

This comes from the build. It compiles perfectly for nRF52840DK but not for the 53DK. I uploaded the project.

Thank you.

Hello,

Ok, so it looks like both the zigbee library and the NFC library are using the same default timer when running on the nRF53 (which is not the case for nRF52840). Timer 2 is used by the zigbee library, and I don't think there is an easy way to change this. However, you can change the timer used by the NFC library, as described here:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/nfc/doc/integration_notes.html?highlight=timer2

So try to look for 

NRFX_NFCT_CONFIG_TIMER_INSTANCE_ID in nrfx_config_nrf5340_application.h, and set it to e.g. 1. 

Whatever timer you set this to, you need to also enable from your project configuration file. If you set it to use TIMER1, then add:

CONFIG_NRFX_TIMER1=y

Best regards,

Edvin

Thank you Edvin. The workaround worked perfectly!
