CCS/CC3220S-LAUNCHXL: we are getting the timeout Error when trying to connect the module using Uniflash

Hi,

We are facing problem in flashing the code to CC3220MODASF module using JTAG with CC3220SF LAUNCHXL Debugger. We are getting the timeout Error when trying to connect the module using Uniflash. In CCS we are getting the following Error when trying to Flash the code.

I have followed CC3220 SimpleLink™ Wi-Fi® and Internet of Things Solution  Getting Started Guide for Uniflash.

 

We have found that the SOP2 is always high by default due to which it is struck in UARTLOAD mode (but in data sheet it is mentioned that all the SOP are pulled low).

please let us know.
