Rick, just wanted to find a way to express my gratitude for you having created this delightful piece of work! 👍

(After an abrupt departure and a 3-year pause, I've just found myself here around again, now finally/hopefully getting myself into using your lib in earnest. Also, I was pretty much shocked, to be honest, to find out that the only feedback to this project have come also from me (in 2015)... I completely forgot about that. :) (FYI, at that time I had just ripped your equally wonderful MSP430 GDB bootloader only, as that was all I needed then.))

Thank you!

As you correctly noted it in a comment yourself ("TODO: probably should reset clock and P1.3 button), please definitely do the button part, because that subtle inconsistency can have serious consequences that may easily remain unnoticed.

Just disable the pullup; P1REN = 0 would do fine.

(As I can see now with a scope, switching the port bit to output will leave the pull-up enabled, so the pin cannot reliably be driven low (if at all).
It won't cause problems on the Launchpad, but it rendered my setup unusable: P1.3 is output here, switching another module off when LOW, but was failing while the bootloader was sitting in the flash.)

I'll need to programmatically trigger bootstrap mode of gdb_bootloader from the fw.
Could you recommend a simple way other than writing some flag to flash?
Like... how easy would it be to get the bootloader be hooked optinoally to NMI instead of RST?
Or, just jumping over to an exported entry address (somewhere after checking the GPIO)? (You already have a "TODO: expose common routines..." in the BSL code. ;) ) Thanks!
