Re: [Paparazzi-devel] Lisa/M Bootloader Question

[Chris Gough]

Hi Luke,

I'm only one step ahead of you. I have a Lisa/M with a JTag connector
and a FLOSS JTag programmer/debugger, but no documentation on how to
use them. Searching the wiki for Jtag, I found info about debugging
but not installing firmware.

any hints?
