Is your thesis in humanitarian area? ;-) Engineers don't guess, they test, prove and implement ;-). Just try to run haret in "research" mode and see if it can give any useful info on internals. To make it boot Linux, it of course will need changes. > > > >> If I give you some logs like the ones explained here: > >> http://www.handhelds.org/moin/moin.cgi/HaRET_20Documentation > >> (Pollings GIOs and so on...) is it easy for you to adapt > >> Haret to PXA 310?

Heh. Then he appears to be either that kind of pain-in-the guy, or maybe PDA porting alumni who wants you to make something good to the community while you write the thesis. And what kind of thesis is that? If it's term/yearly type one, the guy wants to play tricks at you, go shame him. But if it's graduation type work, you should be glad he doesn't make you solder your own hardware design, because otherwise, building (almost) complete system bottom up is pretty good task for an engineering to prove he's in industry ;-). > > > >> Is it safe to test current Haret versions on my PXA 310. > >> Which machine type should I set? > > > > Just launching haret should cause no issues (no warranty of course). > Ok. > > In particular, you'll want to run the steps outlined in the "Early > > logging" section from > > http://www.handhelds.org/moin/moin.cgi/HaRET_20Documentation > > and forward the resulting haretlog.txt file to this list. > I've read this part of the documentation.

I'm not sure 2.6.24 has it all, but it's for sure available publicly. The code, not documentation. > > > > > The mtype is determined by the linux kernel that you are trying to > > run.

Also, a machine type is just a number, there's nothing magic in it. All magic lies in the code which interprets that number.
