zephyr_pre0.elf section `noinit' will not fit in region RAM on ncs v2.4.2

[snowuyl]

I would like to use nRF52832 DK to test Nordic UART Service (NUS). But west build failed with the following messages. What is meaning of "zephyr_pre0.elf section `noinit' will not fit in region RAM on ncs v2.4.2" and how to fix it?

west build -b nrf52832dk_nrf52832

Hello,

Did you try to build peripheral_uart sample on nrf52 Dk? If it is nrf sample, there should not be any problem of memory size of RAM. I have built this for recent version of NCSand v2.4.2 version you tried. This is ok here.

Thanks for your reply! I am not using peripheral_usrt samples.

[Kazi Afroza Sultana]

which sample you are working on? Is this a custom sample?

[snowuyl]

Yes, it is custom sample.
