Re: bootmenu initfs flasher updated for OS2008
 
At the moment, I am not interested in MMC booting (I just got it yesterday, from what I see, if I want to boot a dump of OS2007, I'll have to flash back).
But the USB Network Recovery Mode does sound great (due to my habit of "bricking" things) but I am unsure if I use the default N800 config supplied (bootmenu.conf.n800.example), I will be able to still reboot into my internal flash after a 10 sec timeout? (I really don't want to brick it because I don't have a Linux install ATM and my Dad will kill me if it don't boot :\)

Thank you.

You don't need to add bootmenu.conf and unless you set different root device name or press menu key at boot time, there is no significant difference, the menu will be hidden and it will still boot directly from flash (no timeout, no slowdown).

So I need to have a copy of the 2007 kernel image available to 2008 and the 2008 image to 2007. Do they need to be in /mnt/initfs, or can they be elsewhere?
If you don't use custom kernel, dafault kernel can be extracted from firmware .bin image via
Code:
flasher-3.0 -u -F firmwareimagename.bin
Get the zImage file.

initfs.bootmenu.jffs2 in initfs_flasher directory. This is created when you install bootmenu. You probably have two of them one in each OS200x installation. Just copy them to the other system or have both on SD card. Both initfs and kernel can be on SD but the flashers needs to be in internal flash. Then you can run something like
Code:
kernel_flasher/kernel_flash /media/mmc2/zImage-OS200x
initfs_flasher/initfs_flash /media/mmc2/initfs.OS200x.jffs2
and let it reboot and select matching OS200x item for current kernel and initfs version.

Unfortunately you need to confirm flashing of both parts. In next version of flashers I will add -f option to disable the confirmation.

I have repeated the installation process to no avail.
Yes, people reported similar issues also with 8GB cards. I got 8GB card few days ago, partitioned via sfdisk on device and cloned it via tar and have no problem so I am not sure what is wrong here, see http://www.internettablettalk.com/fo...682#post131682
I think either partitioning or cloning went somehow wrong for you.

w00t, thank you :). I flashed it fine and it works great. I just have one small question, the extra unneeded stuff that is removed, is there any way to get it back (i.e reflash image again)? I'm not bothered if you cant, but I am just interested out of curiosity.

Thank you for the flasher and all your help.

So you actually logged in over usb networking?

Either you flash the backup initfs.orig.jffs2 image created by initfs_flasher (if you answered yes to backup question) or you can extract initfs image from firmware .bin image.

I tried but Putty keeps timing out. I don't know if I have the drivers installed properly or if my computer hates me (I chose to install the dropbear and the ssh server). But I will try on a linux machine sometime.

To fix this I had to add an entry to the boot menu to boot from partition 2 of what would normally be the external card. This was discussed back on page 5 of this thread for more info on what to do if this is your problem. If you do have two cards in try booting with only the internal card in first to see if that works.
Thanks for the suggestion, vormund. I read about that situation but I don't think that's the problem here. It will not boot from SD if there is a card in the external slot or not.

Actually reformatted and partitioned now about four times (just to make sure). Each time cloned without errors. Card and file system look as they should when viewed on my Mac too.

Re: bootmenu initfs flasher updated for OS2008
 
Fanoush,
I think I know what's up with the mmc's switching. The device nodes for the mmc's are reversed between the initfs and the root fs!

If I do-
# cd /mnt/initfs/dev && ls -l mmcblk*

I get-
brw------- 1 root root 254, 0 ..... mmcblk0
...
brw------- 1 root root 254, 8 ..... mmcblk1

if I do-
# cd /dev && ls -l mmcblk*

I get-
brw------- 1 root root 254, 8 ..... mmcblk0
...
brw------- 1 root root 254, 0 ..... mmcblk1
...

The nodes are reversed. mmcblk0 is 254, 8 and mmcblk1 is 254, 0. I'm going to make the initfs /dev entries match the root filesystem and see if it bricks my tablet. I'll post back in a bit

kernelpanic ;-)
