STM32 and Programming via Boundary Scan

Hello, im currently writing on my B.thesis about boundary scan and its implementation. I`ve found enough informations about the principle of boundary scan and how to test with BS. However, i didnt find a lot informations about using BS to program a µC. Can anyone provide my informations about programming with BS? How efficient is it? Another question that has to be answer is if BS is useful for our products. We have quite a lot analogue devices such as analogue control stages or other complex analogue components. In some cases, we only have 1-2 digital devices (µC,..) on the PCB. Is it useful

confused by STM32F207IGT6

? The board is also different. Like Devkit1207 board basedon STM32F207IGT6 and Devkit8500D board based on TI DM3730, can you tell why one is only 120MHZ, and one is 1GHZ. Thank you in advance.

STM32F207IGT6 is from ST, it is ARM Cortex-M3 processor. DM3730 is from TI, it is ARM Cortex-A8 processor. They are different processors based on different ARM cores.
