Combining nRF52810 and nRF52832 in one project

[T IJ]

Hello DevZone,

I am using Segger embedded studio with multiple build configurations for the two chips and I am having some issues to get the program to compile my nRF52810 code.

I have started using the template_project from SDK 17.0.2 and removed all unnecessary includes that I won't need. 

My build configurations are:

Where I removed some from the common configuration and added unique things for both controllers such as flash/ram size, floating point unit (810 does not have one I believe).

Currently I do not have any code written, just an empty project as it is when you open the template_project.

My common preprocessor definitions are:

APP_TIMER_V2
APP_TIMER_V2_RTC1_ENABLED
CONFIG_GPIO_AS_PINRESET
INITIALIZE_USER_SECTIONS
NO_VTOR_CONFIG
BOARD_PCA10040

For the 832 I have:

DEBUG
DEBUG_NRF
APP_TIMER_V2
APP_TIMER_V2_RTC1_ENABLED
BOARD_PCA10040
CONFIG_GPIO_AS_PINRESET
FLOAT_ABI_HARD
INITIALIZE_USER_SECTIONS
NO_VTOR_CONFIG
NRF52
NRF52832_XXAA
NRF52_PAN_74

And the 810 I have:

DEBUG
DEBUG_NRF
APP_TIMER_V2
APP_TIMER_V2_RTC1_ENABLED
BOARD_PCA10040
BSP_DEFINES_ONLY
CONFIG_GPIO_AS_PINRESET
DEVELOP_IN_NRF52832
FLOAT_ABI_SOFT
INITIALIZE_USER_SECTIONS
NO_VTOR_CONFIG
NRF52810_XXAA
NRF52_PAN_74
NRFX_COREDEP_DELAY_US_LOOP_CYCLES=3

I have changed the ses_startup and system according to the right microcontroller. 

I am able to compile the project for the 832 but not for the 810, it gives me an error saying that it cannot find run section .fs_data_run referenced in fs_data.

I have a feeling I am missing one configuration setting but I have a hard time finding it. I even tried looking for differences between a pca10040 and pca10040e project but could not find any.

Hi there,

Could you try to compare the flace_placement.xml files of the template and your example, and see if there is anything related to fs_data that is missing? You can find the file in the SES folder.

If I view the flash_placement.xml from the hardware examples of the nRF52810 I do not find any fs_data in those.

Even if I remove the line it will not compile, it mentions that it cannot create the linker file because of missing things. (It does not show what it is missing)

Maybe you can tell me what instance uses the fs_data parameters, I would be able to tell if I will be needing those functionality

Hi,

I think it might be related to the flash storage module. The template example includes a lot of stuff that you probably don't need, I think the Blinky example is much easier to start with.

Well I do not need to use the softdevice so starting from a project that doesn't use the softdevice seems to be a logical thing to do.

I however did compare both SDK_config files and disabled 99% of all features followed by disabling and removing all unused libraries loaded in the project and managed to get my program compiled for both the 810 and 832.

Preferably I would have started my project from an example project where only the microcontroller stuff and log are loaded and enabled instead of a project where everything is loaded.
