Softdevice not running code

[Tarik]

Hi, I load the s110 softdevice (I tried many versions 5, 6 and 7) When I load my app on the SOC using Keil and the nrf_xxaa_s110 (256) target, the app doesn't run. I'm using latest SDK version (6.1.0).

Any help please

Ensure you fully erase the chip first, then load the soft device, then load the App. There is some info in the nRF51822-EK user Guide and nAN-36 App Note about this, but anything in the SDK latest documentation seems to supercede this.

Check the iROM1 and iRAM1 settings match the softdevice version, it changes. There is a migration document included with s110v6.0.0 and s110v7.0.0 (migration doc not included with the updates like 7.1.0 so get it from the base release X.0.0)

Unfortunately could not find anything useful information on nAN-36, and couldn't find any migration document
