    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
