Hello,
Thanks, the whole package compiled on my computer quite cleanly. Just one thing about it:
On demo-1.0, the file src/main.cxx, line 37:
string cmd;
I haven't made use of cscope to see where it comes from. As I didn't see it being used on main.cxx, I just commented that line and it compiled.
About the rest, I'm a bit confused. I don't understand why a bootloader as the one pointed out by Byron is suitable for uploading a hex bootfile to a chip, but then I need a programmer to do the same. So if I want to get on with your project pierre I might need to buy a programmer anyway? Isn't it possible to use the generated bootfile with such a bootloader?
Today I've been looking for prices on programmers, I can't get them cheaper than about 60 euros, which I find really expensive.
I also wanted to ask about some books somebody could recommend me on this subject if possible.
Kind Regards.
