XxOmarxX member of the Hannspad.fr devteam, did a new rom based on the _[Ac3]_ GtaComb33.
This rom integrated an application which allow you to switch between Usb Host /Usb slave.

A lot of thanks to the creator of the GtabComb, Ab73 the creator of the kernel Adamv4 and our dev's: [_Ac3_] for his help and Fredlys for his test

hi there omar


ram swap is very good thing to patch in kernel for some reasons.. for example 32MB ram swap is heavily compressed to 4x ratio so you get a very fast 128MB virtual swap space and damn fast as it's in ram.. very good and very used in cyano kernels.. there is some patch to do (easy): google compcache or ask rotation user, he managed to get it moduled in .32


i'm also getting some bsods; give a look to other kernels as i've seen somebody managed to get rid of them in .32 kernels


usually es file explorer mounts system in write mode but it gives an error here (even in terminal emulator it's impossible as it's read only).. in gtacomb it mount correctly and is write enabled even using simple console..

kind regards

ahaaa great desdelsur!! you solved that


@omar

swap is putting memory pages on disk for later use (faster than regenerating them but slower than having same pages in memory)

but compacache does compression to swap (up to 4x ratio) and puts it in ram disk rather than to a delicate nand flash memory (you decide the size of ram to use .. usually 32MB is enough as it contains almost 128MB non compressed memory pages)

so this was innovation that entered official kernel tree (staging) in 2.6.34 .. for .32 you have to patch the kernel to get it

android likes it in heavy usage and low memory situations

Hello,

rotation and antibyte are doing a great job on their modded kernel release
witch features an activated compcache. (based on fards ab kernel mod, here is rotations github)

I am using one of their releases and it is the best kernel (at least for me)
when it comes to running the Flashback 10 ROM. I have been using it with activated
compchace since weeks now and it does help a lot in therms of multitasking.

If you ant to try it out, just install one of therir kernels and load a script
like this here:

Code:
#!/system/bin/sh<br />
insmod /system/lib/modules/lzo_compress.ko;<br />
insmod /system/lib/modules/lzo_decompress.ko;<br />
insmod /system/lib/modules/zram.ko num_devices=2;<br />
echo 26214400 > /sys/block/zram0/disksize;<br />
echo 26214400 > /sys/block/zram1/disksize;<br />
mkswap /dev/block/zram0;<br />
mkswap /dev/block/zram1;<br />
swapon -p 100 /dev/block/zram0;<br />
swapon -p 100 /dev/block/zram1; <br />
echo 60 > /proc/sys/vm/swappiness;
It is bacially what rotation had suggested on his topic@Androidhilfe.de .
Different is just a decreased ammount of ram used by compcache and
an increased value for the swappiness in order to use the cache more
freqently.

Bacially its a trade. One trades cpu performance against more RAM. For
most of my applications the cpu is more then fast enaugh, but RAM is
always not enaugh available. So its a fair deal for me.

What works for me is:

1. Create a file named script.sh with a text editor.

2. Copy the code into that file

3. Run script manager (search in the market for script manager)

4. Select the script and set it to run at boot as root

5. Open Termainal (you can get a terminal programm via market)

6. Enter the command "free". There should be a line named "SWAP" in the output.

not that bad belive me


ok, if you are using ubuntu or derived distro here's an easy ppa
https://launchpad.net/~linaro-maintainers/+archive/toolchain

here some guidance
Code:
#You can also install the latest version 4.6 (recommended) on Lucid and Maverick:<br />
<br />
sudo add-apt-repository ppa:linaro-maintainers/toolchain<br />
 sudo apt-get update<br />
 sudo apt-get install gcc-4.6-arm-linux-gnueabi<br />
it depends a lot on what version you are on (ubuntu) because late editions (11,04 and 11.10) have linaro already in repositories

Hi all!

Before i wan't to say thanks to XxOmarxX and all other making usb host possible!!!

Will receive soon my otg cable.
But can't live with a lot of cables and hubs with me, so here it is:

i have found 5V on the hannspad motherboard! i just wan't your opinion to know if it's useable!
if so, i will connect an interupt like sayd few pages before, and use a fuse to limit the risks.

I decided to give this a try and I have found it to be quicker than the last rom I tried but I cannot get the market place to work. It comes up with the stupid error about being unable to establish a reliable connection to the server

Things I have tried:-
Updating Market to 3.4.4
Clearing data from in settings - applications
Factory reset
Wiped Cache
Tried to sign in to market, youtube, gtalk, gmail
Installed Flash 10.1

I can browse the internet without any issue and can even sign in to google without a problem.

Worked fine on the rom I was using before - gtabcomb

any ideas?

edit - oh also tried setting my phone up as a wireless hotspot and I still couldn't get the market to work that way
