smp_server sample: build failure on nRF5340

[samuel4]

Hey

I am struggeling to build the smp_server sample for the nRF5340:

west build -p -b nrf5340dk/nrf5340/cpuapp/ns -- -DFILE_SUFFIX="nrf5340_bt"

fails with a linker error:

zephyr\zephyr_pre0.elf section bss' will not fit in region RAM'
region `RAM' overflowed by 257960 bytes

Adding --sysbuild doesn't change anything. Any ideas on this? Anything missing on my west call? Thanks for any guidance.

NCS version: v3.1.1 and v3.1.0

Best regards

Hi Samuel,

The sample is not tested with non-secure build (with TF-M), but it seems like you only need to modify line 8 in sysbuild.cmake so that it looks like this instead to also apply to non-secure builds:

  if(SB_CONFIG_SOC_NRF5340_CPUAPP OR SB_CONFIG_SOC_NRF5340_CPUAPP_NS)

PS: While that does also not support TF-M out of the box, you may want to look at the mutli image DFU sample that support nRF5340 which is currently in main: dfu_multi_image.
