This appears to be a firmware question about WICED, so I would move it to the WICED Forum.
Issue is related to clock setup on stm32F205. At this failure point, the firmware is not attempted to be downloaded yet.
Have you made any changes to hardware or platform files related to RTC setup or PLL setup?
Clock setup for the platform could be found in .../Wiced/Platform/SN8205x/platform_common_config.h configuration file.
