Multiple definition of `UARTE0_UART0_IRQHandler':

[Rohit Rajapure]

Hello All, 

I am using nRF52840 Dev-kit and SDK 4.0 for Zigbee and thread. Due to some functions, we are using SDK 4.0 for this project which is not present in SDK 4.1.

I interfacing the UART0 in my thread example. I am getting the below errors. 

"../../../external/openthread/lib/nrf52840/gcc/libopenthread-nrf52840-sdk.a(uart.c.o): in function `UARTE0_UART0_IRQHandler':

multiple definition of `UARTE0_UART0_IRQHandler'; Output/Executable_1 Release External/Obj/nrfx_prs.o:D:\Project\Eurotronics\Thread_Radiator\nRF5_SDK_for_Thread_and_Zigbee_v4.0.0_dc7186b\examples\thread\Thread_VAS_20211024/../../../modules/nrfx/drivers/src/prs/nrfx_prs.c:81: first defined here"

I have used thread MTD as a reference example - I have removed the cli library to make UART free. I have all the procedures to make UART0 free for my application. 

Before this I tried to use UART in the freeRTOS_Blinky example and which worked successfully. So I decided to port in thread example. But I am getting the above-mentioned error. 

Also, I referred to some nordic forum links regarding the same error, I tried the suggested in sdk_config.h file but still getting the same error. 

And, if I tried to exclude the "nrf_prs" then I get these below errors. 

"1> c:/program files (x86)/gnu arm embedded toolchain/10 2021.07/bin/../lib/gcc/arm-none-eabi/10.3.1/../../../../arm-none-eabi/bin/ld.exe: missing --end-group; added as last command line option

Let me know how to resolve this issue, 

Thanks and Regards

Hi, 

Any update regarding this?

I think this issue is with libopenthread-nrf52840-SDK.a library. Because, when tried to include the UART and Openthread step by step. I observed that after adding open thread libraries to the project I got the multiple definition error.

I need an alternative library file from SDK 4.0. So that I can use UART as well as the open thread library. 

Urgent!

Let me know your feedback on this as early as possible. 

Thanks and Regards

Hello, 

Please reply. 

I am waiting for feedback. Urgent for me to solve this issue. 

I need an open thread library file that does not use UART.

Thanks and Regards

Hi Rohit R,

I am sorry for the late reply. The default compile settings for the OpenThread stack uses UART0 instance. You can try to use another UART instance, for example you can try using UART1 instead?

Best regards,

Hi Marjeris,

Thanks for the feedback. 

But is it not possible to rebuild the library and make UART0 free for our option. I need UART0 as I have already developed a function on it and using in Zigbee and other protocols. We need to keep it the same for all protocols of the nRF devices. 

Please share the details to make the library file rebuild procedure and make UART0 free. 

Thanks for understanding.

Hi,

- I have removed the cli library to make UART free

Removing the CLI libraries if you are not using it should be fine. Can I ask what have you removed so far and which example are you basing your application on? You may need to remove prs and other source files.

You can also use this guide for recompiling the library and remove the UART0 files: https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/thread_ot_libraries_building.html
