Which OS is best suited for N770?

What is the latest version of ITOS 2006 and ITOS 2007?

I am a newbie.. just bought N770 and 2GB Mobile MMC.. Could someone please suggest me the best way to go?

My current OS versions is ITOS 1.2006.26-8

I have also downloaded the latest ITOS 2007 HE (SU-18_2007HACKER_2.2006.47-17_PR_F5_MR0_ARM.bin) from Nokia site.

I really got confused, whether to flash with OS 2006 edition v. 3.2006.49-2 or the Hacker edition? Which one is latest??

Some people are talking about http://fanoush.wz.cz/maemo/ kernel patches. Do I need to install these patches on 2006 version OS or 2007 OS?

Please help me................

1.2006.26-8 was/is the first version of OS 2006, and is pretty old (August 2006 I think). You definately want to upgrade this - it doesn't even support 2GB MMC.

If you want good stability and the device working as more-or-less promised, upgrade to OS 2006 3.2006.49-2 (this is the final version of OS 2006). This version does support 2GB MMC.

If you want to test the bleeding edge and don't care if stuff doesn't work a bit or not at all, upgrade to the Beta of OS 2007HE which is currently 2.2006.47-17 - this is pretty much a proof of concept rather than a finished article.

There are various patches on fanoush's site, but if you are referring to the high speed MMC patches, install these on OS 2006. They may possibly work on OS 2007HE as well, as I believe OS 2007HE is using the same kernel as OS 2006 (although I could be wrong, in which case you could end up with a non-booting device - just replace the original OS 2007HE kernel from the FIASCO image in that case, or reflash to recover).

A newer version of OS 2007 HE is due in the coming weeks.

I can confirm that fanoush's high-speed MMC kernel zImage-su-18-200639-2gb-mmcplus52Mhz-multiblockw.zip works fine with the current HE 2.2006.47-17, but it depends very much on the MMC brand/model. I have 2GB Kingston with MMC4 support. Follow the instructions on the fanoush's site and test the kernel before flashing at least one day. Or wait for the new HE :-)

Hi Milhouse,

Thank you so much.

I feel that better way to go with dual boot with latest ITOS 2006 and ITOS 2007 hack... and find out the best suited platform for my activities.

Thanks namorvx...

I really wanted to have this patch installed ... I will try it out soon.

How do i know that whether my MMC will support MMC4 or not?

Anyways.. which MMC specification is the latest supported for N770 to get the best performance?

Your suggestions are more appreciated.....

The tiny problem is that even if a card claims MMC4.1 support, it needn't run properly on the high-speed MMC kernel. You have to test it with your card(s). But I can tell you that high-speed mode with multiblock writes is significantly faster then the standard 12MHz one. Give the modified kernel a try. Good luck!

This site is incredible! You guys have answered my question before I even posed / posted it!

The card has 13 contacts (two rows). Plain MMC has 7.

MMC4.1 i.e all MMCmobile cards currently on market.

MMC4.2 is newest and adds >=4GB support just like SDHC but I think you can't buy such cards yet. These won't work with current kernels but patch is trivial so once they are on market support can be added.

As for performace - unless you want to flash kernel which support high speed MMC modes it doesn't matter which card you have in N770.

If you decide to use such kernel than is matters if the card supports only 26Mhz mode (all mmcmobile/mmcplus cards must support this) or can run at 52Mhz too (this mode is optional). You can find this only by testing. There are mmcmobile cards that support only 26Mhz mode (i.e. only half of maximum speed possible in N770).

Also it depends if the card is stable with N770 or not. For me the Kingston 2GB works fine and can do the fastest mode. I am not sure about other cards. Definitely there is some reason why Nokia restricts MMC clock to 12Mhz in their N770 kernel so YMMV.

For testing we have to use command "flasher -l -b ..." as per http://fanoush.wz.cz/maemo/. Is this flasher Fanoush's flasher http://fanoush.wz.cz/maemo/#kernelflasher or is it the flasher from nokia site. The nokia site seems to work only from linus laptop over cable. But I do not have linux laptop. Can I use Fanoush's flasher to test ?

No. Linux is already running on the tablet when you run my flasher so it is too late to load Linux kernel to RAM. You can only flash it permanently and reboot. Nokia flasher talks to bootloader before Linux is booted so it can do such things.

Use linux live CD or vmware player to run nokia linux flasher.

Hi Fanoush,

Thanks a lot.
