Hi,
i created this post last week and TI employee think this is a XDSTOOL problem between CCS6.2 version 50 and the BLE Stack 2.2 examples.
Here is my post 
The problem i am facing is that i cant flash my device from CCS. If i use flash programmer 2 it works.
Any known issues on CCS6.2 verison 50?
Regards,
Michael
