n800 ext2 kernel module not working

anybody got a working one? We going to be booting off mmc or sd any time soon? Sure could use a cifs.ko also.

I cant wait until everything catches up, this ugly duckling is growing on me!!

I've not tried it (N800 still in the mail) but I remember reading somewhere that the extension cards have to be formatted as FAT16/32 ? I did think it strange at the time..

Even stranger to ship a kernel module that does not work, though. Try calling 'file' on it and see if it's a proper module? It should be an ELF 32-bit binary.

Well, I don't have the device so it is a bit hard for me to find out what are the changes in newer firmware for n880 so bootmenu/dualboot will wait. Anyone kind enough to post first four bytes of MAC address of N880 device (i.e xx:xx:xx:xx:....)? And then maybe betatest modified initfs or provide more detailed info to me? 'dmesg' output rigt after boot, 'df' output, 'cat /proc/partitions' would be useful.

N880 with 2 slots would be ideal for booting from big rootfs on the internal card.

yes sorry, the wlan one is needed, control panel ->device->about, i hope the first half (6 or maybe 8 digits) is enough if you don't want to disclose more.

Hi Fanoush

Very interested in this and it looks like rjungmann has redited the post with the N800 mac. I for one appreciate bootmenu and hope you can get it working for the new tablet.

Cheers
Rich

Fanoush, I look forward to helping you in any way I can, please let me know if you need anything. I want to boot from slot, it was great, and gave me great way to have a failsafe os and its very easy to backup with dd and cifs.

I have a 2GB kingston RSMMC with full size adapter in the external slot and the included minisd in the full size SD adapter on the internal slot. The 2GB card in my bootable 770 card. I am also using its 64mb swap partition.

The dmesg would not fit in the previous post, so here is the dmesg, internettablettalk has a 10000 character limit apparently, its the first time I hit it.

I ran into this earlier today. You need one more module before ext2.ko-- mbcache.ko Once you insmod that first ext2.ko will load.

[fanoush]

Fanoush, I look forward to helping you in any way I can, please let me know if you need anything.

Thanks for your help and posted information guys. No additional info is needed now. So far I've examined initfs in n800 firmware and it is based on newer uclibc (0.9.28) so I need to recompile evkey (executable that read key presses in bootmenu) with newer uclibc toolchain. Will take some time (downloading, setting up). I'll let you know when I have something to try.

[penguinbait]

Fanoush, great let me know, I just need the patch, I am ready to test.

Larry, thanks that worked great, I now have my ext2 partitions mounted


anyone got a working cifs.ko yet?

[fanoush]

Fanoush, great let me know, I just need the patch, I am ready to test.
OK, experimental version released, please let me know how it goes.

It may not work at all so make sure you know how to recover.
