Looking for a 5600 kernel....
« on: February 02, 2004, 10:54:58 pm »
that supports wireless extensions. I want to rgulate the bit rate of my Ambicom WL1100C, but can\'t seem to find any kernels. Does anyone know where I can find a good one? I\'ve tried OZ, but thats still way to unstable currently.

The latest versions of the kernel there should have Wireless Extensions compiled in (and you get the speed boost too). You can use the pre-emptive only kernel if you don\'t want the overclocking feature.

Despite the reports that this kernel is stable,  I\'m seeing some unusual behavior that I didn\'t have before.  The first is what appears to be a repeatable crash of the Calendar app.  If I pick the month display tab, the program quits and returns to the regular desktop.  I\'m also seeing some general nervousness with pen input, like the calibration is not right.  I\'ve tried re-calibrating but it still seems to be flaky.  The last oddity is that some of the directories on a CF card got renamed to single letters.   It\'s possible this occurred when the card was mounted in an external reader but it\'s very odd just the same.

Is there a version of the Socket Spectrum driver that has been compiled for the Sharp ROM on the SL-5600?   The driver at ZSI appears to be for the SL-5500...

The Calendar crash is a common problem, nothing to do with the kernel:
http://www.zaurususergroup.com/modules.php...s&id_cat=22#295

Are you using a precompiled kernel or ced\'s howto? I haven\'t heard any reports of trouchscreen/calibration problems with the kernel I compiled. The original instructions in ced\'s howto caused touchscreen problems, so further down his howto he gave more instructions that removed the touchscreen problem.

Haven\'t heard any problems with CF cards.

The Spectrum driver just needs compiling for the 2.4.18 kernel. The latest Sharp ROM for the SL5500 uses the same version of the 2.4.18 kernel as the SL5600 and should be compatible. Is the current driver for the earlier 2.4.6 kernel based Sharp ROMs?

Ok, first problem solved, OpenSSH installation got me.  Still, it seems to be rather stupid that the Calender app should be reading any files other than its own.  Defeating the file permissions doesn\'t seem like a good solution either.

I used the pre-compiled kernel.  The updater script ignored it the first time around, but it worked today.  I need to migrate a RH9 system to Fedora before I try making my own.

The Spectrum driver at KSI installed another module directory for what I believe was the 2.4.6 kernel.  There were files with the names: herme,
orinoco (2), and spectrum_cs.  I did notice that the spectrum driver has been merged with the orinoco driver.  Again, I need to get a system set up to build it and the card hasn\'t arrived yet.

Thanks,
Mike

Greetings.  First of all, my thanks for producing these alternative kernel versions.  I have tried v1.2 of the pre-emptive standard kernel patch (on a v1.32 ROM) and encountered a docking station problem (I sync to a XP box).  The situation I am about to describe involves a 5600 with a partially drained battery and the battery charging status when docked.  I normally dock the Z while it is powered down and then turn it on once it is seated.  Without the patch, the yellow battery charging LED is lit both before and after powering up the Z, and the battery icon in the system tray is animated.  With the patch installed, the battery LED is lit prior to powering up the Z but turns off once the Z is running.  The battery icon is steady and indicates that the battery is fully charged (which is not the case).  However, although I am not comfortable doing this, I did notice that if I dock the Z while it is powered up, the problem goes away (i.e. LED on, system tray battery animated).  I apologize if this situation has already been addressed in another thread and would appreciate a redirect if this is the case.

BTW, I really didn\'t perceive a speed difference when running applications with the patch installed.  The Hancom suite of programs, for example, still required about the same amount of time to load (between 1.5 to 4 seconds depending on the program).  Aside from running a Dhrystone benchmark, can someone point out which applications or functions I should clearly see a benefit from the cache errata workaround.

I have installed this kernel, but do not see a problem with battery LED or icon.

Oddly enough,  I don\'t really see a speed increase either.  From a terminal window, enter the command: \"uname -a\"

I\'m getting this output:

Linux zaurus 2.4.18-rmk7-pxa3-embedix #1 Sun, 18 Jan 2004 01:05:37 +0000 armv5tel unknown

which should help determine what kernel it is...

I\'d still like to find a way to see the boot messages when it boots.  dmesg seems to be filled with a lot of useless information at times.

Thanks Mike for verifying the lack of a perceivable speed increase.   Just to confirm, this is what I get for the following queries:

cpuinfo:
Intel XScale-PXA250 rev 4 (v5l)

Version (with patch installed):
Linux version 2.4.18-rmk7-pxa3-embedix-021129 (colin@paravel) (gcc version 2.95.2 19991024 (release)) #1 Sun, 18 Jan 2004 01:05:37 +0000

Dhrystone Benchmark, VAX MIPS rating:
112.927 (v1.32 ROM w/o patch and running VNC server)
146.236 (v1.32 ROM w/o patch and not running VNC server)
227.788 (v1.32 ROM w/ patch and not running VNC server)

As a sanity check, I reflashed the ROM with v1.32 and reinstalled the patch but still have the same battery indication problem.  I found that the Z didn\'t need to be in the docking station.  Plugging the AC adapter directly into the Z produced the same effect.  I should point out that I keep my screen at half-brightness when running solely on battery.  The screen goes to full brightness when the AC is plugged in with or without the patch.  I just can\'t tell if the battery is getting charged properly (or at all) when the patch is installed.

Although I have no idea what any of the hex values stand for, I provide the following apm information, with the patch installed, if it helps shed some light on the problem.  Note that when I did this, the battery was nearly (but not completely) charged to capacity:

running solely on battery:
1.14 1.2 0x02 0x00 0x00 0x01 100% -1 ?

AC plugged in first, followed by powering up Z; battery LED turns off, battery icon steady:
1.14 1.2 0x02 0x01 0x00 0x01 100% -1 ?

Z powered up first, followed by plugging in AC; battery LED turns on, battery icon animated:
1.14 1.2 0x02 0x01 0x03 0x08 255% -1 ?

Regardless, it seems I might have a unique situation since no one else is reporting a similar problem.  Since the patch doesn\'t speed up the applications or functions I use most anyway, I will revert back to the basic standard kernel.  Thanks again.

Did you try moving those files into the corresponding folder for the kernel you are currently using (should be 2.4.18-rmk7-pxa3-embedix).  It worked fine for me.  I didn\'t do any recompiling of the source.

Just out of curiosity, why do you say you have to migrate your RH9 system to Fedora before compiling.  I ask because I am running RH9, and I\'d like to compile my own kernel for my Z.

Another data point here,  I\'d been using the premptive kernel (1.2) before and didn\'t seem to have any real problems.  This morning I loaded the special kernel (1.1) and the touch screen refused to work at all.  The keyboard and buttons still worked so I was able to reflash to a different kernel.

Since Sharp\'s Zaurus page seems to be down indefinitely now, are there any mirrors of their instructions on building the cross-development tools and the Zaurus kernel?

TIA,

Not yet, it seems to work anyway.  Only WEP isn\'t working at this point.   An odd thing that I noticed is that even though I picked the network connection that required WEP, it eventually rolled over to another one that didn\'t  (at least 2 of my neighbors have open access points).

Just because I didn\'t want to recreate the setup under Fedora a second time.  I downloaded the isos for RH9 without realizing that you have to pay the man in order to get updates from them.  Using FreeBSD for 5 years, I\'ve always been able to get free updates via CVS,  but I did have a quarterly CD subscription as well.  The Linux world just isn\'t the same.
