Sorry for the late reply. Based on this post: devzone.nordicsemi.com/.../ Were you able to get it to work?

My chip is a nRF51822-QFAA.

I attached a picture with SD 8.0.0. The firmware name is unknow.

hello Stian, yes, I did. I tried with SD 8.0.0 and 7.1.0 with no luck. However, the example from mbed.org compiler works fine for me and it has SD 7.1.0. In fact, it has SD 7.1.0 and application code all in just one .hex file.

Did you have a look at the compatibility matrix i linked to in my answer? It is all answered there;) SDK 8 goes with SD 8

I have edited my post. I did what you said: install the last SDK and last SD and it is still not working. Where is the problem ? What I always do is: first I flash the application and then I flash the SD

In that case you must use SD 7.0.0. In the picture you posted, you are flashing with SD 6.0.0. If you are starting with nRF51 development now, you should consider using the newest SD and SDK. version 8

nRF51 SDK v. 6.1.0

Which SDK version are you using?

so, If the memory addresses are right, what do you think is my problem ?

There are many versions of the SoftDevice and the SDK. You must choose the ones that are compatible with each other and the chip revision. Have a look at the compatibility matrix here: www.nordicsemi.com/.../99084712

Memory location 0x14000 is used by SoftDevice 6.x and and 0x16000 is used by SoftDevice 7.x. If you want to change the application start addresses in keil so they correspond with the SD, you can go to Options in Keil, and change the start addresses under the C/C++ fan. To see the IRAM and IROM start addresses have a look in the SD specification.
