are the mtd parts susceptible to something like r/w permissions switching with the data not sticking? first off everythign gets written, then when you dont want root and sys to get written, data doesnt anymore and then "doesnt stick" perhaps?

hmm .. not sure. but i do know i dumped nand after an install and there was stuff there. Then a reboot and it was all blank.

may need to enable debugging on yaffs. or more importantly see if there are checkpoints being made. i'm trying all this now but its taking a while.

Just wanted to say again, thank you so much for all of your hard work. Don't know if you saw, but I did manage to get my git push to work. I tested by commenting out the modules part that breaks our boot. I have a couple of other commits that I'll try to make tonight to fix the sbin folder and fix a couple of other things with init.

thats awesome... as i keep testing this i see more and more weird stuff.

# cat /proc/yaffs |grep check
always_check_erased.. 0
blocks_in_checkpt.... 2
always_check_erased.. 0
blocks_in_checkpt.... 1
# cat /proc/yaffs |grep check
always_check_erased.. 0
blocks_in_checkpt.... 2
always_check_erased.. 0
blocks_in_checkpt.... 0

this is the same session in android. But look at the checkpoint.. it actually went back to 0..

latest theory is spl might be wiping nand. i cant prove it yet but thats what i gather from convos.

wonder if cmonex might know something from when she was working on HSPL. How exactly does tinboot stay resident, and how does WinMo do it? Maybe we need to use yang to develop a true NBH with all the parts like WinMo and reference them based on the addresses given to yang?

Guys here is my initrd.gz file. I added .zip so I can up it here just remove it.

Not working:
Keeping data after Reboot.
Data (3G/EV icon is there)
Wi-Fi
Keyboard. (Most likely in the init, all the files should be there.)
Might be others...

Everything else seem to work great.

My androidinstall.tar should not be too different from yours but it you want it let me know.

Edit: This also has Nate's latest SBIN folder with the addition of the adbd file. (tested)

Thanks for the post, I'll look through it when I get home. Just as an FYI, a lot of those files get copied over into the system when all is said and done, so we could just merge those into the system ahead of time and yank in out of initrd. That would give us a faster boot and reduce the overall size.

That being said, I don't think the size of initrd is the cause of the problem here. Because my phone is already hosed, I'm going to be making some risky changes to tinboot in an effort to mimic the WinMo OS layout and address ranges. I'm going to actually try compiling everything into an NBH and see what happens...

For data, have you tried manually setting it up in the APN settings?
