how to define 2 boards for the same application

[ziv123]

hello Nordic 

i have a project than works with nrf52840 and ncs (zephyr) 

i want to have the same application running on nrf52832 as well, as part of a single code base strategy.

now i work with the nrf tool in for the vs code IDE,  

i added a board and i a build configuration for the second board, but i don't understand how can both boards work with the same CMakeLists.txt, pm_static.yaml and prj.conf, since they are the same for both boards in the same application 

obviously they require different partitioning since they don't have same memory size, that is just an example

any ideas on best practice for how to do that ?

 

hope to read from you soon

best regards

Ziv

Hi,

I see this was answered in the Zephyr discord server.

[ziv123]

i wrote this question in discord, the answer does not really describe the application should be structure which is what i am trying to understand 

can you be more descriptive .. 

1. does my application dir should contain 2 pm_statics - pm_static.bord1.yml and pm_static.board2.yml ?

if so, where do i define to which pm_static to go to ?, or they should, along with a CMakeLists.txt be inside the board1, or board2 directories ?

same goes for prj.conf, do i need to have board1.conf and board2.conf in each board directory ? 

also, do i need to somehow re config the (green) files here:

?

Yes.

You can have that if needed.

See how it's done for the nrf_desktop application where APPLICATION_CONFIG_DIR is used.

https://github.com/nrfconnect/sdk-nrf/blob/v1.9.1/applications/nrf_desktop/CMakeLists.txt#L19

Also see this link: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/scripts/partition_manager/partition_manager.html#configuring-static-partitions

Yes.

if i do that and i remove the pm_static.yml and replace it with pm_static_board1.yml and pm_static_board2.yml, then i get an error during build 

here is part of the build log

any ideas what i am doing wrong ?

one more thing, when i create another board_x.conf, then it is only reachable under application directory, if i put the .conf in each board directory the build does not find it why ?

my CMakeLists.txt, looks like this with regards to boards and .conf files:

set(BOARD_ROOT ${CMAKE_CURRENT_LIST_DIR}/../)
if(DEFINED BOARD=halo_ep2)
    set(BOARD halo_ep2)
    if(NOT DEFINED OVERLAY_CONFIG)
        set(OVERLAY_CONFIG halo_ep2.conf)
    endif()    
else()
    set(BOARD canary_proto_rev_4)
    if(NOT DEFINED OVERLAY_CONFIG)
        set(OVERLAY_CONFIG canary_proto_rev_4.conf)
    endif() 
endif()

hope to read from you soon

best regards

You only renamed the file? The content is the same? If you don't set a pm_static file, how does the BUILD_DIR/partitions.yml file look like? Try taking that, and rename it to pm_static_baord1.yml and use that instead.

Try doing a pristine build. How does the folder structure look like? You have a boards folder in the application directory with all the overlays and .configs? Or do you have a configuration/"board_name_x" directory ?
