Although I have not tried to boot any other device-adapted Linux with

Is Haret ready (in development version) for PXA 310?
I don't know of anyone that has used haret on a PXA 310.
:( I supposed it.
Unfortunately, my understanding is that Marvell does not publish the
register level specifications for the PXA chip. As a result of this,
we have no way of knowing if haret needs to be changed or not to
support the cpu.
Is there an small probability that Haret does not need to be changed?
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?
It takes how long usually to adapt Haret to a new processor type?
With docs, it probably takes a day or so. Without docs, it could take
several months of dedicated reverse engineering.
I can't spend so long time in my thesis waiting for reverse engineering.
In fact the thesis objetive is not reverse engineering but using an
application inside java inside a linux that it is inside a pda but I
think my thesis director has not choosen the right pda.
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 might do it if it is worthy
(I have some doubts about Marvell not publishing register level
specifications.)
The mtype is determined by the linux kernel that you are trying to
run. You're either going to find someone else that has ported linux
to your device - in which case, they'll list the mtype - or, you're
going to have to port linux yourself.
I have found the machine type.
It's 1388.

C coding skills and advanced knowledge of the linux kernel internals.
And yet again advanced knowledge of the linux kernel internals is not
inside my thesis objetives.
You can find other developers familiar with Linux ports to handhelds
on irc at #htc-linux on irc.freenode.net.
Ok, thank you.
While you decide to answer me about if it is worthy to even test Haret
on Hp Ipaq 114 (I have to ask my thesis director for the pda. I have to
spend some time on the tests and I have not too much time.) I am going
to try to edit the wiki so that there is a link to the haret mailing
list web interface instead of just the maling list mail and I will
probably fix two or more three things.
Thank you for your knowledge, again.
