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 ?

[ziv123]

the yml issue was solved by adding this line to the CMakeLists.txt, don't know if it is ok practice or just a workaround because something else is not right..

set(PM_STATIC_YML_FILE ${CMAKE_SOURCE_DIR}/pm_static_${BOARD}.yml)

regarding the .conf i don't hold a .overlay file, just the .conf file inside the boards/arm/board1 directory where the .dts and .defconfig etc. are at, but if the .conf stay at the the directory where the CMakeLists.txt is then it is found. 

 

there is actually a another problem and maybe it relates to other problems i see, part of my CMakeLists.txt looks like this:

set(BOARD_ROOT ${CMAKE_CURRENT_LIST_DIR}/../)
set(PM_STATIC_YML_FILE ${CMAKE_SOURCE_DIR}/pm_static_${BOARD}.yml)
if(BOARD_HALO_EP2)
    if(NOT DEFINED OVERLAY_CONFIG)
        set(OVERLAY_CONFIG halo_ep2.conf)
    endif()    
elseif(BOARD_CANARY_PROTO_REV_4)
    if(NOT DEFINED OVERLAY_CONFIG)
        set(OVERLAY_CONFIG canary_proto_rev_4.conf)
    endif() 
endif()

and then i have a problem with .conf at the directory that is works, but if change the "elseif(BOARD_CANARY_PROTO_REV_4)" to just "else()" then there is no problem with the canary_proto_rev_4.conf, like the "BOARD_CANARY_PROTO_REV_4 is not defines/configured, but in the west comman generated by the nrf connect extension for vs code i can see there is " --board canary_proto_rev_4" and in my board directory (boards/arm/canary_proto_rev_4) there is a Kconfig.board file and this is its content:

config BOARD_CANARY_PROTO_REV_4
	bool "BOARD_CANARY_PROTO_REV_4"
	depends on SOC_NRF52840_QIAA

so why does it looks like it the board is not defined ?

 

p.s. also tried like this before, "elseif(DEFINED BOARD=canary_proto_rev_4)" and also tried with "if

(CONFIG_BOARD_CANARY_PROTO_REV_4)

one more strange thing is that in the application/build_canary/zephyr build directory there is the CMakeCache.txt and there i see  - "BOARD:UNINITIALIZED=canary_proto_rev_4" why is UNINITIALIZED ??

and same affect: 

hope to read from you soon

best regards
