Hi Usman,

There is too few details to give any certain answer. It could be an issue with the crystal oscillator. Are the crystal specifications within the CC2650 requirements? Is the layout ok?

Note that kickstarting the crystal by connecting it to VDDS is not really safe, you could break the IC.

Cheers,
Fredrik
