PCA10000 and SDK 11

[Lee]

I'm trying to build the blinky example in SDK 11 and load it onto a PCA10000. I'm using the make file in PCA10031/blank/armgcc and am building this under linux. If I use blinky_blank_pca10031.hex which is in the hex directory, then I can load and run this using JLinkExe. Can anybody help explain what I am doing wrong. Thanks

All SDK examples from SDK 7.x.x and later are by default configured for the xxAC variant which has 32K of RAM instead of 16K. So since you are working on a 16K RAM variant you need to adjust the linker settings accordingly if you haven't done so already?

E.g., correct settings for the \nRF5_SDK_11.0.0\examples\peripheral\blinky\pca10028\blank\armgcc example:

/* Linker script to configure memory regions. */

SEARCH_DIR(.)GROUP(-lgcc -lc -lnosys)

MEMORY{

FLASH (rx) : ORIGIN = 0x0, LENGTH = 0x40000

RAM (rwx) : ORIGIN = 0x20000000, LENGTH = 0x4000  //changed from 0x8000

}

SECTIONS{

.fs_data : { PROVIDE(__start_fs_data = .);

KEEP(*(.fs_data)) PROVIDE(__stop_fs_data = .);

} > RAM} INSERT AFTER .data;

INCLUDE "nrf5x_common.ld"
