You may have to do some matching.
The J-TAG signals of the MCU are routed to module pins as follows from the data sheet.
From module, the JTAG signals are routed to FTDI chip and the test points on the EVB.
Perhaps the test points on the EVB populated with headers and the Olimex J-TAG programmer connected to the matching pins on the EVB test points.
From Wiced SDK, pleas use the following make target for Olimex J-TAG programmer:
For scan app it would be like this:
snip.scan-SN8200x-debug JTAG=Olimex_ARM-USB-TINY-H download run
I have not tested this yet but I will give it a try later.
