Downloading softdevice and application(using SDK) from Linux system to nrf51822 yunjia board.

[akhil]

hi , I am trying to download the softdevice(v8) and cross compiled application(using makefile in nrf51822 sdk v6) from my Linux PC using JLinkExe. following is the memory layout of my softdevice :

following steps show how i downloaded the softdevice to nrf51822 using JLinkExe from my linux PC.

next I have to download the application which I compiled using the sdk and its makefile. but I don't know to which location I should load it to like I did for softdevice sec1,2 and sec3. Thank you in advance.

You can flash the softdevice directly using loadbin in JLinkExe:

loadbin s110_nrf51_8.0.0_softdevice.hex 0x0  #flash in address location 0

Since you are using softdevice 8 the application should be flashed to location 0x18000. This is documented in the softdevice specification: infocenter.nordicsemi.com/.../s110.html In section 11.2 "Memory resource map and usage" (APP_CODE_BASE)

loadbin application.hex 0x18000  #flash in address location 0x18000

Check out this thread to see how to make a script that erase and flash SD and app (this is for nRF52, so just change device to nrf51822 and app address to 0x18000)

thank you for the thread regarding the application code base address.
