multiple definition of `UARTE0_UART0_IRQHandler'

[tinytrex]

I have a bunch of nRF52810 kit. I am creating a BLE central device which would dicover and conenct to one or more BLE peripherals. I am using nRF SDK 15.3.0 and it has an example for BLE peripheral device for nRF52810 which uses S112. However, It doesn't really has an example code for BLE central device meant for nRF52810 using S112. I am trying to port/modify an existing BLE central example (nRF5_SDK_15.3.0_59ac345\examples\ble_central\ble_app_uart_c\pca10040\s132\ses) which originally was written for nRF52832 and uses S132 to nRF52810 using S112. I have made the necessary changes in the project configuration but I see the following error whenever I try to build the code:

1> C:/Program Files/SEGGER/SEGGER Embedded Studio for ARM 4.16/gcc/arm-none-eabi/bin/ld: Output/ble_app_uart_c_pca10040_s112 Release/Obj/nrfx_uarte.o: in function `UARTE0_UART0_IRQHandler':

I am attaching the project configuration file for your refrence.

For some reason I am unable to upload the emProject file as an attachment. So I am zipping and attaching the same.ble_app_uart_c_pca10040_s132 - Copy.7z

Disabling one of the definitions resolves this issue. Howewver, I still need to figure why the other projects do not complain about it. So far, I think I am good.

Hi,

Uploading the project file gives no details on your configuration. Please zip the entire example directory and upload it.

I would recommend that you compare your configurations in the sdk_config.h file with the one found in pca10040e project for ble_app_uart (peripheral) example for the following and sub-configs: 

• UART_ENABLED
• NRFX_UART_ENABLED
• NRFX_UARTE_ENABLED

Best regards,
Jørgen

Dear Jørgen, I have zipped everything and atatched here. The path to the example is: nRF5_SDK_15.3.0_59ac345\examples\ble_central\ble_app_uart_c\pca10040\s132\ses

nRF5_SDK_15.3.0_59ac345.7z

There are two ways to solve this issue.

1. Disable legacy UART peripheral support. This is done by setting '#define UART_LEGACY_SUPPORT 0' in your sdk_config.h file.
2. Enable peripheral resource sharing for UART and UARTE. This is done by setting '#define NRFX_PRS_ENABLED 1' and '#define NRFX_PRS_BOX_2_ENABLED 1' in your sdk_config.h file.
