Hi Martin,
Thanks for getting back to me - no problem on delayed reply as I'm
looking after my two boys whilst trying to do some work. It's chaos.
No problem also on using the genode lists. I may initially ask some very
dumb questions as I haven't touched assembler work and processors since
the early 80's.
I have quickly scanned through your base_hw. Thank you so much for
really documenting the code so well - at a first glance it looks as
though a port should be straight forward.
For the next two weeks I have to manage a 9 year old and a twelve year
old and will attempt a port on my own if and when I get a chance. (I
can't believe I was so badly behaved at those ages). After that we're on
holiday in France until the beginning of September. From September
onwards I hope to devote one day a week to this.
Thanks again for being supportive and offering your help.
Cheers,
Nick
