Yup I did test it.... but it was still a no go. I haven't been able to make aa good bootable build all day.

I wasn't able to get ahold of JooJoBee666 today so hopefully tomorrow he willbe able to help. :)

ahh its all good. I ran a test with a small initrd and it didnt boot. So now im thinking that size isnt the only problem.

i barely had any time today so im looking forward to the weekend to tackle this

Well that's good to know. I figured out how to change the partation table so I will play with it some more today.

I might have some time this weekend... The wife is already going to kill me anyways! But she is running Android too and I hope to have her switched over to NAND this weekend.

Now they got the Server_Bug figured out it she will be happy! :)

Update:

I was able to get it to boot this morning. What is your ETA on adding LZMA compression?

woa really.. you were able to boot with a modded partition table ?

well i started studying the lzma patch yesterday and i can have it done by sat morning, but if you have it booting without it then there may be no need. The initrd is so huge because of all the busybox crap we have in there. Nate is right about that, its just really big. Can we get a smaller busybox with just the bare essentials.

I took apart some initrds from real android devices and they are tiny. Mainly because they dont have modded scripts or busybox to do the installation for them.

So correct me if im wrong here, but doesnt that mean we just need busybox to install and thats it? i think android already auto mounts everything else so thers is no need to mount it on the initrd. anyways just a theory..

Hehe, ACL, the two files we need to consider changing are adbd and busybox. I've already looked into both busybox and mtd_utils (which has our flash_erase). It is possible to compile busybox with only the commands that we use during boot, and man are there a ton of them in there that we don't use... I think I can get busybox down to around 400K, compile flash_erase independently, and then maybe find a smaller version of adbd. Realistically, I think we can do this in the 1.1 MB envelope you were wanting :)

For mounting sys before Android does it for us, we need to mount it to make changes like keyboard layout, LCD density, and cmdline stuff.

That is really great news! Did you just hex edit the partition table? I'll be putting together some nice documentation on what I've done for busybox and tinboot once I get it all ironed out. I'm trying to get my hands on a couple TP2's from work to mtty and find the exact memory addresses we need :)

To test yesterday i took the initrd from a cyanogen build which was only abotu 200k. Thats when i realized there is absolutely nothing in there besides the empty directories to mount everything. The androird rc had all the mount points needed so no script work had to be done.

once we have that lets shoot it over to lmiller since he has it booting with a modded table

Dont worry about the keyboard poop at all. That is handled by the android update. What this does is permanently modify /system with the correct stuff so you dont need to mount bind it at all. thnk about it, would you replace your tp2 keyboard layout? Same goes for the density. Cmdline cannot change, it should not change. Its just bad practice.

Re: NAND Boot Testing - 01-07: Panel power on/off fixes

Yes it was with the modded table.
I'm pretty sure we should be able to change the size of the NBH... But I haven't figured that out just yet.

If one of you could pass me the initrd.gz that would be great.

Here is what my table looks like:

Re: NAND Boot Testing - 01-07: Panel power on/off fixes

WE HAVE FULL NAND!:thumbleft:

I was able to boot with out the SDCARD!

Touch screen is not working yet so I can't test anything else... BUT!!

ahh this is nice. Ok, so share your part table so we can commit and i will work with nate on the finall install piece.

thanks alot bro.. !
