And with autobuild site 1.5Mb
Why kernel compilation occupies so much a lot of time?
Did all as in the first post for, but linux it is not loaded
And how correctly to collect archive of modules?

Need to 'strip' the modules file.

Pls tell me how can i do it?

Thanks. I guess I better understand the difference. I have been using Haret with testing the other builds. NAND I understand (superficiaqlly) also replaced the WinMo bootloader? That is a bit too radical for me. Have read of a few phones bricked that way.

I wanted to compile a kernel. Has started it in the terminal:

sudo apt-get install git-core
sudo apt-get install wine
mkdir android
cd android
git clone git://android.git.kernel.org/platform/prebuilt.git

git clone git://gitorious.org/~acl/linux-on-qualcomm-s-msm/linux-msm-rhod-nand.git

cd android
mkdir modules
cd linux-msm-rhod-nand
make clean
make ARCH=arm htc_msm_nand_defconfig
make ARCH=arm CROSS_COMPILE=~/android/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi- INSTALL_MOD_PATH=~/android/modules zImage modules modules_install

All was compiled perfectly. Has replaced zimage with the and when I start haret.exe in WinMo there are 2 short vibrations and further all freeze. In what my mistake?

Thanks, but I think we have probably both done that and NAND seems a touch scary to me with potential bricking of the phone more likely than with Haret. Is this a misperception?

Pretty difficult to brick the phone, and trust me, I have tried...

We are writing a bootloader (tinboot in this case) to the NAND which is executed, unpacks the kernel, and then runs the init/install scripts. I ended up having to write a document of this post because every time I start to update it, I either get pulled away, or we change something crucial :P

I'm still going to gear this toward NAND because we have a lot more control over cmdline and such with Haret, so you don't need some of the detail for that. I'll have a better explanation of the boot sequence in the Tinboot section too.

Thanks for the help. I seem to have compiled all the modules required for Haret, but they seem located in this directory:

jerryyyyy@jerryyyyy-VirtualBox:~/android/modules/lib/modules/2.6.27.46-01276-g6a6a1c1$

According to the instructions: "Unfortunately, the modules still need to be packaged, so you will need to search for all .ko files, copy them into an empty directory and compress them into a tar.gz. The name will be modules-2.6.27.46-01192-version.tar.gz. "

I guess I need to compress this directiory (hope it is this simple).

I understand you all are busy, as am I, but, interesting to hack away at this....

afaik you don't want to just gzip the directory, what I did is write a short shell script that copies all of the .ko files (searching recursively) to a different folder and then gzips that, using the modues-versionstuff.tar.gz format. I don't remember where I found the example script (could have been the first post or a link from the first post) but I only had to make some small modifications to get it to work.
