Combining the ext2 was just a process of merging it into the rootfs system folder since thats where its mounted to anyway, although I am now thinking of moving it to its own partition. The idea is that you would be able to update any component with a rom flash with out touching the other components. The data file I have not been to worried about as it will be empty on first load anyway. I will bind it to mtd4. I went with 4 partitions because I wanted to have a recovery partition available. Merry Christmas!

Maurice, this sounds awesome. If you have a chance, would you mind PM'ing me the details of your tinboot2.S file or build script as to how you are creating multiple partitions? Also, I thought I could help you out with the keyboard assignment portion. Just replace the keyboard section for init (in rootfs) with this:

Notes: You can leave off the .kb file overrides as I only added those until we got all of the variant values. We still don't have them for all of the rhod100 variants or tilt2 (that I know of), but the variable machine_variant is there to pull from on NAND. Also,

Thanks for the keymap info nate although I want to load the keymaps before loading the root fs so the the keyboards are avail at the init terminal prompt. I think I have that all worked out now. The link attached does not boot into android but is more to show that I do have all of the drivers embedded into the kernel so we have done away with the external modules. I have left the ability to load external modules intact if for some reason someone wanted to. The link I am posting is to the nbh file. Make sure you have you original nbh file to flash back to after testing. You'll notice when booting that all the drivers are initialized during the boot. I am now working on completely re-witting the tinboot, which is the last step before we are completely booting from the nand. The I will re-write the init for the root fs. I have already rewritten the initrd init as you will notice from this test and it is ready to access the rootfs from the nand. I have a heavy workload today so I probably won't get much done with this today but I am still projecting by Friday I will be done.

Awesome news maurice. Keep up the great work, can't wait for full NAND!

[MassStash]

That's awesome Mr. Green! i hear ya on that workload stuff. Got the day off finally however, n tryin to see what i can't test out n try help with. Great work on this man, you're really making peoples dreams come true as well your own I'm sure. haha

can we get an update on any progress acl? still going somewhat smoothly?

Booting mods n kernel 01224 right now....

update: Running really well. For some reason, something i am adding i think is not allowing livewallpapers. silly. But everything else running as it should at this point

update: seems sometimes if i just let the 2min auto panel off go, it will come back on more reliably then actually hitting the end button to turn screen off....

update: How's thangs Mr. Green? get anything in over the last 4days, or stuff that rough for ya lately?? how was the new year's for ya?

Took on five new projects that are demanding a lot of my time. As soon as I can get back to this I will.

If you wouldn't mind, could you zip up your tinboot and initramfs folders and let me take a peek? I'm just curious if you are doing something like this for referencing the partitions:

mtdparts=msm_nand:0x00300000@0x1600000(boot),0x00040000@0x01900000(root),0x066C0000@0x01940000(system),0x08000000@0x08000000(userdata)

I'm also curious how you are creating the partitions
