Bootloader image for nRF51822 without an external XC oscillator for FOTA
I tried using the Booloader + Softdevice default app (mKIT) found here (https://developer.mbed.org/teams/Bluetooth-Low-Energy/wiki/Firmware-Over-the-Air-FOTA-Updates#default-bootloader) to flash my nRF51822 but it seems to stop working once I do this. I was successfully able to load the bootloader and then load an application image on the device using FOTA for the mKIT itself.
I believe that the problem lies in the fact that the nRF51822 I am using does not have an external oscillator crystal but uses the internal RC oscillator. I was wondering if there is a bootloader dfu default app with the mentioned configuration set, or how I can create one myself.
Any response will be much appreciated.

Did you ever find a solution to this Anuraag? We're seeing the same thing. Used to work fine but seems to no longer support LFCLKSRC of RC.
