I see. I did some quick testing and it looks like it should be possible to run it on 51822xxAA :) In mesh/api/nrf_mesh_config_core.h set NRF_MESH_LOG_ENABLE 0 and reduce the PACKET_MGR_MEMORY_POOL_SIZE to, e.g., 512. Furthermore, reduce the __HEAP_SIZE to, e.g., 256 in toolchain/gcc/gcc_startup_nrf51.S (if building with GCC). The linker file should also be updated to match the RAM specification for the 51822xxAA. I just changed the toolchain/s130_nrf51422xxAC.ld file to RAM (rwx) : ORIGIN = 0x200022D8, LENGTH = 0x1d28. I also built with the -DCMAKE_BUILD_TYPE=RelWithDebInfo and -DPERSISTENT_STORAGE=OFF CMake configuration and GCC ARM embedded 6.3.1. With this I was able to build for the reduced size RAM 51_light_control_server target successfully.

Best,
Thomas

Hi Thomas

Thanks for going to the trouble of getting it to work on the 16k device.

I will be building with gcc, and I'm familiar with changing the linker file, as its needed to make some of the SDK examples work on the QFAA device

I'm not going to have time to try this today, but I will try later in the week.

Thanks again

Roger
