Comilation error for nRF51-DK1 board (nRF 51822) template project BLE_Button

Hi, I created a new project for nRF51-DK1 board, the template project BLE_Button. Their is one compilation error: Error: Undefined symbol assert_nrf_callback (referred from /extras/mbed/TARGET_NRF51_DK/TOOLCHAIN_ARM_STD/app_pwm.o).

I think this error is due to the update of mbed OS, as it was fine before Feb 2018.

Please fix the bug.

Regards Helen

Hello Helen,

Can you try compiling with the mbed-os version of the project?

I was able to compile it with the nRF51-DK. Hope this helps!

Hi Karen, Thanks for working on this. Yes I am able to compile by importing the example. But it is now impossible to creat a new project for nRF51-DK, even the HelloWorld template gives the following error message: Error: Symbol user_perthread_libspace multiply defined (by /build/mbed-os.lib/rtos/TARGET_CORTEX/rtx5/RTX/Source/rtx_lib.NRF51_DK.o and /build/mbed-os.lib/rtos/TARGET_CORTEX/mbed_boot.NRF51_DK.o). Regards Helen

Hello Helen,

There is a github issue that has been raised for that error:

https://github.com/ARMmbed/mbed-os/issues/7422

It seems like Jerome has a found a solution that may work for you. Under the Compile button, navigate to Compile Macros and add _RTE_ in the text box. Then try recompiling. Hope that helps!

Thanks. It solved the blinky error: symbol user_pthread_... but the BLE problem that has the message: Undefined symbol assert_nrf_callback.... is still there.

Hi,

Same thing here...I am trying to compile a program for nRF51-DK and the following error appears : Error: Undefined symbol assert_nrf_callback (referred from /extras/mbed/TARGET_NRF51_DK/TOOLCHAIN_ARM_STD/app_pwm.o).

NB : I can compile using the following target : Nordic nRF51822

Regards, Fred

Hello Frederic,

I would suggest trying to compile with an older version of the mbed 2 library. You could also import and compile a program that uses the mbed-os library (programs that are mbed 5 enabled) such as these:

Hope this helps!

Hi Karen,

Using an older version of the mbed 2 library is working! Thank a lot!
