Problems with adding openthread to gcc BLE project

[marmio]

Hi,

I'm trying to add Openthread support to my project, which is based on ATT_MTU_Throughput example. I followed the tutorial in infocenter, but I still have some problems in linking stage:

Thanks from advance for your help.

Hi,

The first problem of multiple defines of RTC2_IRQHandler, is due to both OpenThread stack and ATT_MTU_throughput example using RTC2. ATT_MTU example use RTC2 for implementing a counter, and this counter needs to be implemented using other method/resources if you want to combine the OpenThread stack with this example. RTC0 and RTC1 cannot be used either, as these are used by the softdevice and app_timer respectively.

The other errors related to __flash_data_start/__flash_data_end could be caused by wrong linker script used for compilation. What Makefile/linker script do you use for your project? The default linker script for Thread/BLE multiprotocol examples are located in:

[THREAD_SDK_ROOT]/external/openthread/linker_scripts/openthread_nrf52840_multiprotocol.ld

Best regards,

Jørgen

ok, NRF_LOG_BACKEND_USES_ UART should be 0 ;)
