No, i just confused by myself. tongue.gif
Then again, since my debian rootfs is already in a primary partition in /dev/hda1, i am not sure whether it is possible to move it into a new extended partition (say /dev/hda4 as the first logical partition in the extended partition), becoming:
hda1 (factory hdd files), hda2 (factory hdd files), hda3 (extended user space for Sharp/Cacko), {hda4 (new debian root), hda5 (swap)}

could you start a cacko/debian thread with your results, methods etc? 2or0's kernel sounds like sufficient progress for debian to be compelling, the cacko dual boot covers the pda needs. the 2.4 kernel & modules could maybe be listed (are you using a new tetsu or eviljazz kernel?) the means for getting qtmail to talk to gmail, etc would be handy...... and some basic info on how well it works, the possiblities of going back and forth with 1-click(though the transition might take a minute or 2), that sort of thing.

C1000 + kernel 2.6.24.3 + Sharp loader = no problems found
Thanks 2or0

Here you go:

As for the one-click thing... perhaps I (anyone can do this easily) can just package up the dualbooting ingredients (individual kernel + booting script) with an item added to the root program menu in the WM (IceWM or LXDE).

Now running this new kernel (hda1) with overclocking (416 mhz -> 624 mhz). Works great. Thank you!

Is it possible to down clocking? And how to change CPU clock?

Yes, you can. I am using the "CPU config" tool from pdaXrom repackaged by 2or0 for debian.

After change cpu clock, dmesg shows:
Set frequeny to 62400 with L:16, 2N:6, B:1, Turbo Mode, A:1
Calibrating delay loop.. 622.59 BogoMIPS(lpj=3112960)
sharpsl-pm sharps-pm: Waring: Can not read main battery!

Problems:
1. Calibrate is not work since change cpu freq. I have to reboot to get it working again.
2. Battery status is wrong.

Sometimes I get message:
Unkwnon HZ value! (87) Assume 100.

Why?

Yes... I noticed this also. Is it because the CPU Config tool does not change the voltage accordingly?

I am not sure the LCD Clock is related to Calibrating or not.

Since PXA270, we should change LCD Clock when cpu clock changed.
The following config is used in mb-applet-powerctrl. They are very stable stable in C1000, C3XXX.

[PXA270]
# do not change below
PathCCCR=/proc/zaurus/CCCR
PathVCORE=/proc/zaurus/VCORE
MaxFreq=5
DefaultFreq=3

#cpu clock, CCCR, VCORE
freq0=104,2000204,4,1
freq1=208,2000206,6,1
freq2=312,2000208,8,1
freq3=416,2000210,a,1
#2000210: CPU clock 416MHz system bus 208MHz LCD104MHz(default)

freq4=520,2000214,c,1
#freq4=520,2000290,c,1
#a000214: CPU clock 520MHz system bus 260MHz LCD130MHz
#2000290: CPU clock 520MHz system bus 208MHz LCD104MHz
#2000214: CPU clock 520MHz system bus 260MHz LCD 64MHz

freq5=624,2000218,e,1
#freq5=624,2000310,e,1
#a000218: CPU clock 624MHz system bus 312MHz LCD156MHz
#2000310: CPU clock 624MHz system bus 208MHz LCD104MHz
#2000218: CPU clock 624MHz system bus 312MHz LCD 78MHz

As you know, the cpufreq patch has the bug that the kernel shows the error-"Can not read main battery!"- when you change the voltage using dvfm. So I modified the patch by fixing the 412MHz voltage as 1500 mV instead of 1400 mV. At least I don't have the complaint. But I don't know what I have to do to correct the other errors.

I have never seen a kernel 2.6 change cpu freq of zaurus very well. So we can not get any solution worked.

It is may the best way to reading the kernel 2.4's source related with VCORE and CCCR.

Dear 2or0, I would like to ask you for a vmlinux version of your kernel.

I am testing a kexec backport for linux arm 2.4, hoping to make it work on the sharp rom.
Unfortunately, it doesn't work with bz kernel images, only with uncompressed images.

So could I ask for a vmlinux version of your latest kernel? (sharp bootloader, hda1 version)

Thank you in advance!

Here is vmlinux for kernel 2.6.24.3. Good luck!
