compiler ERROR UART code

[PIRHeisenberg]

Hi, i have been working on initializing the UART periferial based on the UART example in the SDK5. I got following error.

1> error: unplaced section: .log_dynamic_data_balloc_log_mempool [nrf_log_frontend.o], size=4, align=2
1> error: unplaced section: .log_const_data_app [nrf_log_frontend.o], size=8, align=4
1> error: unplaced section: .nrf_balloc [nrf_log_frontend.o], size=28, align=4
1> error: unplaced section: .log_dynamic_data_app [nrf_log_frontend.o], size=4, align=2
1> error: undefined symbol: __start_log_const_data
1> error: undefined symbol: __start_log_filter_data

I know that i probably missed a header file or something simular but i was not able to find out which.

Please help

Hi,

It looks like you are missing definitions for some sections used by the logger library in the linker configuration. If you are using SES(?) you can refer to flash_placement.xml of one of the examples that use logging. There you will see for instance this line:

    <ProgramSection alignment="4" keep="Yes" load="Yes" name=".nrf_balloc" inputsections="*(.nrf_balloc*)" address_symbol="__start_nrf_balloc" end_symbol="__stop_nrf_balloc" />

And similar for log_const_data etc. You need to add these configurations to your project.

<ProgramSection alignment="4" keep="Yes" load="Yes" name=".log_const_data" inputsections="*(SORT(.log_const_data*))" address_symbol="__start_log_const_data" end_symbol="__stop_log_const_data" />
<ProgramSection alignment="4" keep="Yes" load="Yes" name=".nrf_balloc" inputsections="*(.nrf_balloc*)" address_symbol="__start_nrf_balloc" end_symbol="__stop_nrf_balloc" />
<ProgramSection alignment="4" keep="Yes" load="Yes" name=".log_dynamic_data" inputsections="*(SORT(.log_dynamic_data*))" runin=".log_dynamic_data_run"/>
<ProgramSection alignment="4" keep="Yes" load="Yes" name=".log_const_data" inputsections="*(SORT(.log_const_data*))" address_symbol="__start_log_const_data" end_symbol="__stop_log_const_data" />
<ProgramSection alignment="4" keep="Yes" load="Yes" name=".log_dynamic_data" inputsections="*(SORT(.log_dynamic_data*))" runin=".log_dynamic_data_run"/>
<ProgramSection alignment="4" keep="Yes" load="Yes" name=".log_filter_data" inputsections="*(SORT(.log_filter_data*))" runin=".log_filter_data_run"/>
<ProgramSection alignment="4" keep="Yes" load="Yes" name=".nrf_balloc" inputsections="*(.nrf_balloc*)" address_symbol="__start_nrf_balloc" end_symbol="__stop_nrf_balloc" />

I added the following lines to the flash_placement folder but the error Messages are the same

Can you upload your project here so I can look at it and perhaps try to build it?
