You might want to try asking on the irc channel #htc-linux on irc.freenode.net. There are several developers that have ported to new devices that "stop in" periodically. > A) Will the pxa300.c and associated .h files contain all the GPIO settings > etc etc (there are some in there) or do I have to go fiddling around with > HARET to find them out? It will probably have the locations of the gpio registers. (You'll need to teach haret how to use that info.) What the gpio registers do will definitely not be in linux - you'll need to figure that out with haret. > B) Since the kernel apparently has support for the chip, is it fairly > likely to 'just work', if I compile with the appropriate config? No. You need to have kernel code specific to the device (eg, IPAQ214). > C) How much of the kernel code would need to be different for different > devices based on the PXA310, given that most of the hardware is on-chip > (and all the hardware I care about to begin with)? Things like powering on/off headphones, usb, backlight, etc. are all device specific. You'll need to customize the kernel for it. > D) When I do this, I'm going to want to be able to see how far the kernel > gets, i.e some debugging output.

The 'pxafb' may work. If your device uses it (instead of, for example, an ati chip) and Marvell didn't make any drastic changes then it will probably work. Unfortunately, there are no docs, so I don't know if Marvell made any changes. > E) What do I do about the MTYPE, since the IPAQ214 clearly doesn't have one > yet (either in HARET or the kernel)? There is a web site to register a new one: http://www.arm.linux.org.uk/developer/machines/ Good luck, -Kevin _______________________________________________ Haret mailing list [email protected] https://handhelds.org/mailman/listinfo/haret
