[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.

The nRF51422 and nRF51822 are identical. Must be something with your custom board. Have you tried other FW on your board?

[Murugan]

yes i am tried some other programs its working good. But this DFU code only the problem.

Have you modified  the code in any way? There's no reason for the code to work differently on the nR51422 vs the nRF51822. Make sure it work properly on the DK, then try your board. 

[Murugan]

my code work with properly with DK.

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.
