Blinky application doesn't work with SoftDevice S110 on my PCA10028 DK board

[Gloria]

Hi,

I bought two PCA10028 DK boards, try to start with the simple example with SoftDevice S110.

I download the application to the DK board by nRFgo Studio.

First I tried download the SDK example Blinky code to the DK boards, it works, it proves the boards should work normally.

Then I tried application work with SoftDevices S110, but failed. Following is what I did:

(1) open nRFgo Studio, select "Program SoftDevice", select the s110_softdevice.hex comes with SDK, then click "Program" button. It showed successfully downloaded, see the attached file1 picture.

(2)Then I compiled the SDK example blinky_s110, the only change is the "IROM1“ starts from 0x18000, see the attached file2.

(3)Now, download the application Blinky to DK board: in nRFgo Studio, select the "Program Application", select the compiled Blinky.hex, then click on "Program" button.

But, the blinky application didn't work, no LED flashed as before.

Here is the version of my Tools:

(1)SDK 8.0.0

(2)nRFgo Studio v.1.21.0.2.

(3)uVision 5.17.0.0

(4)Windows 10.

(5)PCA10028 V1.1.0 2015.39

What is the problem why I can't get Blinky work with SoftDevices?

BTW, one wired thing is when I compiled all the SDK example application, there's always one error "can't find core_cm0.h”? I added a path "............\components\toolchain\gcc" to pass the compile. Is this OK?

Hope to know it quick.

Thanks a lot,

You seem to have done everything correct. Are you sure you are programming the correct application hex, and why aren't you programming directly from keil? Other than "IROM1" starts from 0x18000, the size should be 0x28000 and on "IRAM1" start should be 0x20002000 and size 0x6000, but I guess this is not the problem if you have not changed anything.
