Thanks

Just follow the link below: link text You need to create a project that will program your flash with softdevice. Read all the comments below!

It works. I can download code to Flash by using ULink2.

I followed this instructions and had hard times to make this work. I was getting an error that "Flash Download Failed" due to the .axf file could not be loaded. Of course this file doesn't exist and after some research I found out that we need to type into the output window the softdevice's name with the extention .hex

Example: s110_nrf51822_7.1.0_softdevice.hex

Hope it helps, Milan.

Try choosing "nRF51xxx external connectivity board" as flash-algorithm, and also check "Erase Full Chip". The "normal" flash algorithm will not erase the chip if a SoftDevice has previously been loaded. I will update my original post to include this information.

I tried already this operation but I always get "Error:Flash Download failed - Cortex-M0". Nevertheless, if I try to program another application (the one is in nAN-36), I have no problems. I suppose there should be anything more...

Hi,

If you follow the steps in this link: www.keil.com/.../uv4_fl_hexdownload.htm

And input the softdevice hex file as the "name of executable", you should be able to flash the SoftDevice using any debugger that supports SWD. Note that you also need to setup the debugger with the "nRF51xxx External Connectivity Board" flash algorithm in "debugger settings" and check "Erase Full Chip".

A limitation by using a non-segger based debugger is that you do not have access to writing to UICR. UICR is used for DFU-based applications.

Cheers, Håkon
