I 'll let you know how well it works with my C750. How would you test it? xev ? Unfortunately during my last testing session some weeks ago the x-image was unusable (no input from touchscreen and broken keyboard-layout). I tried a fresh rebuild yesterday and it broke miserably on do_rootfs. Hopefully I'll find some time to investigate during week-end.

[Angstrom-devel] Patching and development question to fix bug 4259, pxa2xx_udc in angstrom release
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Good morning all, I used to use openzaurus before OE came along. In fact I used to maintain a build for the SL-5600 (poodle?) until it broke. It is so nice to see how professional the project now is compared to when the tools were all shell scripts with hardcoded bin locations! Awesome work. Anyhow someone at work has given me a Zaurus c860 (c7x0). Playing around with angstrom for a bit has highlighted a few things: Firstly the udc clock bug, which is now fixed in kernel 2.6.25 (Bug 4259), and a problem with WPA (bug 4180). I would like to tackle both to push the fixes into the standard distro. FYI I have read the wiki which details policy, but these questions apply to advice on where to start my patching work. I have currently got a building copy of angstrom (it is sooo much easier now guys, thanks so much!) Taking 4259 (pxa2xx_udc) This is fixed in 2.6.25 but I am guessing you won't want to bump the kernel version for this. If I backport the patch (might be easy, maybe not) would that be the best approach? Should I checkout a specific version of the build tree to patch against, and if so what. I haven't thought about how to fix the arc4 issue, apparently you can get some success in building the crypto modules into the kernel. This is a significant change, I don't know how much they will enlarge the kernel by. I guess this is one for discussion. Looking forward to playing with Zauruses (Zauri?) again, - -- Dr Matthew Swabey Rm3229, Bldg59 Zepler School of ECS University of Southampton University Road Southampton, SO17 1BJ England Tel: 02380 597381 -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFIKtB6soSsB2Ynk1ARAjhmAJ9yQ/dfZuPjbcs3+HOJQxUlleA8zACffjUs 4xv9j1AdkDmU0DOsazidl8U= =tpcg -END PGP SIGNATURE- ___ Angstrom-distro-devel mailing list Angstrom-distro-devel@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-devel

I don't have a strong opinion on either option, but I would like at least 2 test reports from users of the chosen option (backport or 2.6.25). 2.6.24 was said to fix loads of stuff and turned out to be broken. regards, Koen ___ Angstrom-distro-devel mailing list Angstrom-distro-devel@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-devel

If 2.6.25 UDC works on PXA27x, there is nothing to do. If not, we should compare them. There are many new features in 2.6.25 (UDC, new wireless stack,...). Porting RP patches to 2.6.25 would be more productive than backporting new features to 2.6.24. Let's start with 2.6.25-rp as clone of 2.6.24-rp and comment out all failing patches with REBASE or DROP note. Then authors of patches will debug and fix it. The underlying problem was linux-rp-2.6.23 in .dev had big issues with suspend/resume. I personally suggested the move to 2.6.24, being desesperated by the *not resuming* device (SL-C860). Moreover Stanislav was working on Sharp remote control and the patches were only for 2.6.24. One line reject fix for 2.6.23 or 2.6.25. Porting to 2.6.26 would require some work (GPIO code changes). I have no confirmation, that it works on akita or c7x0. Especially on C7x0 + CE-RH1, the driver is only my guess. Anyway the 2.6.24 still needs some finishing: If you look at the bottom of the linux-rp-2.6.24.bb you'll see there are no mtd-module.patch for c7x0 but only for akita. Why? mtd-module.patch fixes MTD mapping of PROM, when compiled as module. I added it for machines, which were actually affected. Very minor issue, unless you want to use EN-JP dictionary database in PROM. Fixed in 2.6.25. -- Stanislav Brabec http://www.penguin.cz/~utx/zaurus ___ Angstrom-distro-devel mailing list Angstrom-distro-devel@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-devel
