25 MB partition / 96 MB free on TKC ROM - How?

[Richjn]

Unless sash has changed things since I last looked the kernel in the qtopia packages is the std kernel. As far as I am aware the only difference between the 760 / 860 kernel is the usb storage. As you are using the tkc2.51 rom (which has this element built into the zImage) you should be O.K to use one of the two kernel I have posted to the ZUG one has wireless extensions only (for kismet / Wellenreiter) the other has this plus pre-emptif / overclock ptaches. I stress the word SHOULD be o.k I havvn\'t got a 860 so haven\'t tried but it won\'t kill your Z just flash the previous kernel if it doesn\'t work.

Let me know

Richard..I have a few questions.

1) Are there any known side effects of using your kernels?
2) What is the pre-emptif / overclock ptaches kernel?
3) If I use the pre-emptif / overclock ptaches kernel, what risks am I taking and are they proven risks (i.e. has the risks been realized by anyone). Does the battery discharge faster with this kernel?
4) You mention in your write-up of the kernel that there is a correction for the XScale PXA-250 cache errata bug. I thought the c760/c860 has a XScale PXA-255, so is this still applicable?

1) There are three kernels available a)One by javab0y that adds wireless exstension only (no risks)  My kernel as above + pre-emptif + cache errata on(this allows apps to start up faster / no risks) c) My kernel as above plus overclock (This speeds up the device but may overheat the processor / some risk)

2) See above but you can read a lot more about it by searching here

3) None that I know of / yes the battery will drain faster but not much

4) Yes the 760 /860 use a PXA-255. I was requested to include it so did not sure if applicable or not but with it turned off device runs faster but may crash according to kernel source notes. (Han\'t for me so far)

Richard,
After I installed you kernel (the one without the overclock), my 860 freezes up when the displays dims (this is after leaving it for about 5 minutes or so), maybe just before suspend or when trying to suspend. The only way to recover is to pull out the battery. BTW - this hapends when the Socket Low Powered card is in or not. Any ideas?

2devnull,
I understand you have installed
1) zImage.bin  from Wireless_preemp_cache_on.rar
2) initrd[1].bin-tkrom-2.5.1-slc7x0
3) where did you get updater from?
Can\'t find proper sharp updater.

i used cacko updater. proto updater would work alsp, just needed cacko to do the partition. Also, if you have already installed the ROM, you can just flash the zImage without re-flashing the ROM, therefore remove the initrd.bin file from your SD or CF card. The wireless preemp kernel did not work for me, it kept locking up my system.

BTW - I am using the javab0y kernel until Richard can find out what is wrong

No I can\'t think what would be causing the lockups other than some people have mentioned usb storage device problems with the pre-emptif kernels.

I will build a kernel against the 860 settings with just the wireless patches in place if you wouldn\'t mind testing it for me ? This will show wether I have a fault in my build structure. If it works I will then add the other elements one at a time to see which is causing the lockups (maybe the cache errata which isn\'t included in the overclock version that I use but thats on a 760.

PM me your email address if you want to try this out but please just say if you\'d rather not.

Richard...I don\'t mind at all if it would not brick my device. Once there is a way to recover, I am technical enough to follow the instructions and reserect if needed. I will PM you my email.....thanks.

I succesfully installed tkROM with this zImage (from Wireless_preemp_cache_on.rar). By now installed WLAN CF cards (ASUS and PRETEC) without problems. I rebooted. Everything works great. I prepared the system like that:
updater.sh-slc860
initrd[1].bin-tkrom-2.5.1-slc7x0
zImage.bin from Wireless_preemp_cache_on.rar.  (Is it javab0y kernel ?)
I am going to install Anycom Bluetooth card.
I can say it behaves better than with cacko kernel. I was unable to install WLAN so fast in case of using cacko kernel.

Jurwit,
It looks like you have everything going well. The zImage you are using is Richard\'s, which will confirm that it works correctly with a 860. Now the only difference between your set up and mine is the Socket Wifi Low Power card I am using. I am not sure if this causes the lock-up because I could not get it to connect using Richard\'s kernel. Maybe it has to with some modules that got loaded when the card was inserted. Anyway, glad to hear your setup is working for you. What differences (performance wise) are you readily noticing?

[jurwit]

2devnull, I said only that I have installed WLAN cards without problems. As far as general performance is concerned it is too short time to say something. In general it is pretty fast. Now I am fighting with Ambicom Bluetooth card. Looking for applet for Qtopia (the best for existing Network program). I don\'t like to turn in on/off using commands. I saw it in cacko qtopia, but for tkROM it requires to add something.
