Intermediate L6 E3-> Linking C executable fails: zephyr/zephyr_pre0.elf section `bss' will not fit in region `RAM'

[nRF52_DK_usr]

Hi, building itself works as the code is correct, but it won't fit onto nrf52810. In the example is no exclusion for this Product/nRF52DK.

Building & Linking for an nRF52832 works fine, telling that around 39KB RAM is used, meaning the 24KB of the 52810 are overflowed by nearly 66%.

Am i doing something wrong or Is that supposed to be that way?

Result for the nrf52832:

[169/169] Linking C executable zephyr/zephyr.elf
Memory region         Used Size  Region Size  %age Used
           FLASH:       34460 B       512 KB      6.57%
             RAM:       38976 B        64 KB     59.47%
        IDT_LIST:          0 GB        32 KB      0.00%

Hi, 

nRF52810 has a limited memory size. Please consider other nRF devices with more memory.

Hi Amanda, 

thanks, i suspected/assumed this solution already.

By the way, what is the mentioned 'bss'?

Is that documented?

Its the segment for uninitialized data, mostly buffers and stacks. Linker scripts (.cmd extension) are in build/zephyr subdir. You could also look at the map file there with symbols and byte counts.
