I have sucefully compiled a cyanogen port for the i5500
Now i have to wait for my device to come back from the repair since i managed to erase the bios by using my recovery
I decided to avoid playing with the recovery and flashing cyanogen directly via ODIN

If any one wants to try out my compilation send me an email : motafoca at alquest.com.br

I have sent the link to some people on the cyanogen
Please be patient on the matter, this is a pre alpha version and i dont know how well it will work since my device is beeing fixed. (dont worry its not related to my port )

At dropbox under firmware/myodin.tar.md5

Please send email of how it runs

IT doest startup?

Can anyone try adb shell and see if the linux kernel is up?
So i can figure out whats the status, kernel or graphics
adb can be installed by using google android sdk

Phone maybe friday

adb shell
basic ls / will do
then we see what happens, if adb shell works we know the kernel is up

You can use gtalk from gmail.com

Added on January 11, 2011, 2:44 amIf anyone gets the adb
enter the shell by typing adb shell

then type:
adb shell dmesg >/sdcard/dmesg
adb pull /sdcard/dmesg
send me the dmesg file or post it here

Since the port hasnt worked correcly for now (we will get there)
I share bellow 2 good things to be done to improve performance and battery usage

---------------------------------------------------------------------------------------
For some bugged reason, the phone is at 600mhz Always, thats done because the power "governor" isnt set
You can check it by installing "android system info" and expand the cpu, there it shows the percentage of usage of each clock speed, on mine it was looked at 600mhz
To set it, install busybox, install a terminal emulator and root your device

create a file inside your sdcard with the contents:

echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 95 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/up_threshold
echo 3 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/down_differential
echo 200000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
echo 245760 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

execute the file via terminal
sh /sdcard/filename

Im thinking on how to set this on every boot, for now you have to run it every time you reboot or turn of your phone
------------------------------------------------------------------------

And there is a feature that cyanogen recomends on phones that have low ram (our case) is to activate a swap (virtual ram)
there is a program called swapper v2 (search at appbrain.com), with it you can add this swap to your device by using the SDCard, this improves the performance
I havent tested swapper on my device, hopefully our kernel supports swap and we can use the nice feature
Another thing, using swap on your SDCard will increase its usage and for that reason reduce its life, but since SDCard are quite cheap i belive its worth the usage
If anyones tries swapper share your experience

THanks,

James

Zeam launcher has been considered the faster launcher for android
Give it a try

Added on January 11, 2011, 6:03 amUploading cyanogen-prealpha-revb-i5500.tar.md5 to dropbox/firmware
THis time the filename is wright
This is a much simpler approach, only the system.rfs is changed, the rest is stock
Inside the system.rfs all the files are from cyanogen+samsung files
Give it a try
Thank you all testers

Battery drain on froyo is due the clock, like i said on previous message
You can fix it using set cpu or do my tuto i wrote a few posts ago
If you guys want i can put the fix inside a modified I5500LUY2
The swap partition we can do with a kernel compilation, i have the kernel sources here just need to spend sometime to get it done

-----------------------
If anyone wants to help, please search around a see if you can find the patches made to the kernel repo that create the samsung kernel
Because samsung patches the kernel with their stuff and then removes whats not needed, if we have the patches, we can get the official kernel, patch it and enable swap and multitouch for example. Put it in the I5500LUY2 and go!
--------------------------

Actuall it does support swap, it`s just disabled
I`m inside the samsung kernel now and i can select the swap option

But i rather get the untouched kernel like I said above and enable multitouch also
Can anyone put that in the first post?

Something like:

"How can i Help?"
- Find samsung kernel sources without the "cleanup" or the patches that are applied to the official kernel

Im not flying duchman

Added on January 11, 2011, 7:56 pmi read somewhere that the guy actual figured the patches out and compiled them but couldnt put them inside the device
I can! but i tried to contact him and he didnt answer

Good news is that i can compile the kernel with swap support and the power governor as "ondemand" (yay battery)
The other good news is that we may get multitouch with the kernel i have
I just need help findind the "original" synaptics_i2c_rmi4.c from synaptics
OR a synaptics_i2c_rmi4.c that has multitouch
Help me out forum!

Added on January 11, 2011, 8:31 pmGetting the kernel source from its bigger brother i9000 to see whats in there for multitouch

Changes on kernel:
powersave set do ondemand
swap support
synaptics_i2 modified (maybe multitouch??)
added motafoca at the version now called 2.6.29-motafoca
Packaging and uploading to dropbox in a few minutes

Still uploading, keep your pants on

Error found
Rebuilding, need another 20min

This is the I5500LAROJP2 (I5500LUYJP2) froyo with a kernel rebuild with support for:

- ondemand powersave mode (more battery time)
- swap support (use swapper2)
- MAYBE multitouch

uploading now! FILE I5500LAR0JP2_MODIFIED.tar.md5
Use odin as normal

Added on January 11, 2011, 11:19 pmJust some info
Whenever you change versions its recomended to erase cache and data
-> BUT <- we arent changing versions, so you DONT need to erase cache and data so all your apps and configs remain untouched after odin flash
