Why sometimes BlueNRG-1 Flash gets corrupt on power up?

I'm facing a serious issue with the BlueNRG-1 chip. Its flash sometimes gets corrupt on power up. It is happening due to slow discharging of bulk electrolytic cap of 100uF. When I remove capacitor then it works fine but I can't remove capacitor because I will power this board with the external adaptor in the field. In general all power adaptor has capacitors at the output. So How to solve this problem? Anyone please suggest. I would be really thankful.

Thanks
