I'm a little late to game on this but this last bit of advice (enabling PRS) solved my problem with multiple definition of UARTE0_UART0_IRQHandler too.

If anyone else stumbles on this post when having linker error linker "multiple definitions of function UARTE0_UART0_IRQHandler()" I solved it by disabling Peripheral Resource Sharing Module in sdk_config.h. (#define NRFX_PRS_ENABLED 0)

Hi Håkon,

I want back to my SDK 14 project and converted it again from scratch using the 12k-line sdk_config.h containing everything that the nRF52832 can do, and it's working fine now. I can't reproduce it either with the new SDK. Through time I've moved the sdk_config.h over from 13.0 to 14.0 to 14.2 and I think I missed some essential new value that hadn't been important until SDK 15. Sorry for wasting your time.

Have you added Peripheral Resource Sharing Module (nrfx_prs.c and enabling it in sdk_config.h through NRFX_PRS_ENABLED)?

Hi,

The example $sdk15_path/examples/peripheral/uart/pca10040 will do exactly this, by enabling run-time usage of either UARTE or the UART peripheral.

I am not able to reproduce this issue at my end, by setting UART_EASY_DMA_SUPPORT '1' and UART_LEGACY_SUPPORT '1'. I can confirm that both nrfx_uart.c and nrfx_uarte.c are linked in properly by looking at the .map file.

Could you try the same operation with the uart example, and diff your config with the stock sdk_config.h for that example and see if there's anything that stands out?

Kind regards,

Håkon
