Update BSL for MSP430F5529

Hello,

I have several boards with 5529 MCUs on them. I need to change the BSL on them. Are there instructions on how to do this and what tools are required? Note, these boards are not powered by USB but we do use the USB interface to perform firmware updates on the main code? Thanks.

    Using SBW / JTAG, BSL area can be flashed like main flash, just need to be BSL unlocked first. It is not important is it board powered by USB or not. Probably it can be done by all tools, example with my flasher...
