Symbol UARTE0_UART0_IRQHandler multiply defined (by nrfx_uarte.o and nrfx_uart.o).

I am unable to figure out what causes the problem that IRQ handler is defined both in nrfx_uart and nrfx_uarte modules.

After investigating in a test project I have found that it seems to be best to include all uart modules. nrf_drvuart.c, nrfx_uart.c, nrfx_uarte.c and nrf_serial.c in the project. For sdk_config it seems to be best to enable nrf_drv_uart, nrfx_uarte and nrf_serial. In test project I can skip enabling nrfx_uart and is able to link.

I am trying to use nrf_serial.

But in my real project the best combination of sdk_config still causes problem with:

Symbol UARTE0_UART0_IRQHandler multiply defined (by nrfx_uarte.o and nrfx_uart.o).

I cannot determine why.

Anyone got a clue?

The multible defined IRQ handler can be fixed by setting UART_LEGACY_SUPPORT to 0.

But that just causes another problem with nrf_serial.c line 208

drv_config.use_easy_dma = (p_config->mode == NRF_SERIAL_MODE_DMA);

there is no field "use_easy_dma....."
