linking errors merging ble_app_uart and an SPI app

[Cy]

Hello,

I am merging two applications which work successfully inside SDK 17. One is the ble_app_uart and the other is an SPI app handling my display. The linker can not find instances of nrfx_spim_init'm_init, nrfx_spim_trfx, nrfx_rtc_tick_enable, nrfx_rtc_cc_set, nrfx_rtc_enable. I think it may have something do with the sdh_config.h file but have tried to be thorough in merging of the files from both projects. Any help would be appreciated.

Which UART/E and SPI/M/S instances are you using?

Most likely you're using the same HW peripheral for both applications and the drivers prevents that via #ifdef's in the driver header files. 

Have you enabled the instances in sdk_config.h?
