mmc dev 1

mmc1 is current device

mmc part 1

shows partition map
1 Type c
2 Type 83
3 swap (Type 82)

fatls mmc 1:1 /

lists 132 file(s), 144 dir(s)
but the file/folder names seem to be totally messed up...

so this is problem why u-boot cannot load it.

you can try to backup all files, then format partition to vfat (fat32) and copy files back.

sorry to sound ******ed but can't seem to do this part


Examples:

This tarball http://atrey.karlin.mff.cuni.cz/~pal...12.04-1.tar.gz contains some kernels (stock PR1.3 and stock PR1.3 with framebuffer) and some item files.

For playing & testing download archive to / and unpack it as root:
$ cd / && tar -xf u-boot-images.tar.gz

probably just bieng a fool

but why is this? Filenames are just fine in WinSCP or Putty when doing ls.

Could this be caused by a restored backup optfs?

No, it doesn't work that way. Just do as Pali suggested - at best, it will fix Your problem, at worst, it will filter out possible source of issues. U-Boot is just different kind of low-level, when reading required bits - it may work well via filemanager, SCP or whatever, but be too FCKD up for U-Boot. Which seems to be the case - You said already, that for U-Boot directories/filenames are FCKD.

I found out the reason that causing J4ZZ's problem (and mine). I have (now, had) the same problem too after installing u-boot today for the first time.
The problem is backupmenu. It is creating a .item file in /etc/bootmenu.d/ called backupmenu.item which contains only this line:
u-boot-update-bootmenu can't read this file correctly and then fails while running, throwing some "can't read from /dev/null" error (sorry for not saving the error log ).

I fixed it this way: flashed only the kernel, booted maemo, renamed this /etc/bootmenu.d/backupmenu.item file, reflashed u-boot (run dpkg -i u-boot-flasher...) and finally ran u-boot-update-bootmenu again. Now everything works the way it should have worked.

This is not valid bootmenu item file. u-boot use same file format as fanoush bootmenu and this is invalid.

That's the weird part.. I found no reason for it to be there at all. I looked through backupmenu's .deb and install scripts and found nothing related to /etc/bootmenu.d. I have no idea how it got there. I certainly have not copied it there.

It's half way fixed... Proper U-boot menu is now showing omap1-power50 and all the others, but after selecting default entry all I get is "Starting Kernel..."
and then the phone turns off.

fatls mmc 1:1 / is now displaying correct filenames after backup and mkfs.vfat -F32 /dev/MyDocs... and then restoring.

sorry, but I cannot confirm that. No such *.item file here. But the problem still exists.
