Jason,
I got it.
Now we are trying to put NetBSD on our device. Booting from the =
internal
Flash would be an important issue.
Is there any valuable information about this, no matter Linux or NetBSD
related?
If I am successful on booting by internal Flash, I would share my
experience to others=A1K :-)
If someone has interest on this, we can co-work together=A1K=20
=20
By the way, can NetBSD run well on iPAQ?
Most people are talking about Jornada 720.
=20
Regards,
Colin

Colin,
=20
It's not Flash on the PDA that's erased; it's DRAM. And although =
you
can use a root image, for practical purposes you'll want to have a
NetBSD partition on the CF that contains all of the files Right now
there's no embedded NetBSD so you're loading a whole operating system.
=20
Why is the DRAM erased? WinCE uses DRAM both for programs (when =
they
allocate memory) and for storing files. When NetBSD loads, it erases =
all
of the DRAM to use it.
=20
On the stock Jornada 720, WinCE is in ROM. Files that are stored on
the Jornada while running WinCE are in DRAM (that's why it has a backup
battery). On some (maybe all) iPaq's and other Jornada's, WinCE is
loaded in flash. The NetBSD can be loaded here, but there's no NetBSD
equivalent of embedded Linux yet, so you'll need to put the files on a
CF card. I actually don't know of any NetBSD support for other =
Jornada's
besides the 710/720.

Hi there,
I=A1=A6d like to buy an iPaq or Jornada PDA and try to install NetBSD =
in it.
After browsing some documents, I found that both kernel and root image
are stored in CF disk.
When hpcboot is executed, the NetBSD kernel image in CF would be =
loaded.
My questions are:
1, Why some people say that the Flash in PDA would be erased after =
doing
this?
What data would be stored in it?
2, Is there any method that can put both kernel and root
image in the Flash of PDA and boot by these, like the way embedded =
Linux
PDA does?
=20
Thanks and regards,
Colin
