[Murugan]

Dear Nordic Team,

Thanks for supporting. For secure DFU successfully worked with nRF51422 (DK51 PCA100028). But its not work with my application board based on nRF51822. Please guide anyone.

My SDK12.3.0.

Regards,

Ok, that's good. So we can rule out the FW then. Can you post the schematic and layout please?

Other Firmware is working good. Only Challenge with DFU code.

Looks ok. 

Make sure you set the 32 kHz clock to use the internal RC oscillator and not the XO since you don't have that.
