Uploading ble_app_beacon to nRF51822 Beacon Kit

[Sarah]

Hi,

I'm trying to load the ble_app_beacon application under C:\Nordic Semiconductor\nRF51822 Beacon v1.1.0\Source Code\nrf51_beacon\ble_app_beacon\pca20006\s110\arm_build to the Beacon Kit using the nRF51 DK. I can compile the Keil project under this folder fine, but when I only load nrf51822_beacon_app.hex to the beacon (with no softdevice, using program application tab on nRF go), the beacon does not advertise.

I had also tried uploading SoftDevice 7.1.0 then uploading nrf51822_beacon_app.hex, but I then got "This has file has data in SoftDevice region" error (This was the first thing I tried).

Could you please tell me what I am doing wrong?

As RK, I suspect that this error message indicates that softdevice and application are overlapping in flash memory. To see the ROM settings in Keil, go to Project -> Options for target -> Target Tab. Look at the IROM1 field. It should be Start: 0x16000 and Size: 0x29000

Thanks so much Stefan and RK for giving me the right direction to solve this problem. I posted the solution below.

Apparently for uploading code to work, IROM1 and IRAM1 values needed to be set. I used the values in this post: devzone.nordicsemi.com/.../ and it worked. You go to "Options for Target" in Keil and set these values in Target tab.
