Then I suggest you try to debug your code like described here and maybe start a new thread if you can't figure it out.

I finally managed to program application. I changed memory settings to:

IROM1(on chip): 0x18000(start), 0x28000(size) IRAM1(on chip): 0x20002000(start), 0x4000(size).

still dont know if its correct, because i dont see advertising packets coming (it was working on nrf51DK) in Master Control Panel, but at least there is some improvement.

Flash download failed - "Cortex-M0" is a very common issue and is discussed in many threads here on devzone.

This, this, and this might be a good place to start.

Thank You for Your quick answer.

I selected "J-LINK/J-TRACE Cortex", but now i get this error in Keil:

Flash download failed - "Cortex-M0".

When I try to load .hex file using nRFgo Studio i get the error:

programming failed: this hex file has data in SoftDevice region.

So i think that problem might be in using wrong version of SoftDevice, or incorrect memory settings, and i dont know how to fix this. According to nRF51 Series Compatibility Matrix, this SoftDevice should be suitable for nRF51822_QFAA, so i think this is a memory settings issue. What are correct settings for nRF51822_QFAA?

Keil has a tendency to reset some of your settings when you change target. Including the debugger settings. Try to go into the Debug tab and select J-Link instead of ULINK:

I'm not sure why the "Select Target" drop down list doesn't update, but as long as you have the correct memory settings you should be good anyway.

Using P20 to program should not lead to any troubles at all. If you want you can certainly load the .hex file using nRFgo or nrfjprog as well.
