sergiocampama 7 Posted June 29, 2011 Share Posted June 29, 2011 Hello, I am currently looking into the way the BSL in the MSP430 works.

jsolarski 94 Posted June 30, 2011 Share Posted June 30, 2011 To really get an idea of what is going on inside you need to look at the JTAG doc , or SBW doc. they will give you better insight into whats going on.
