Matan, is that binary for arm? Downloading it to the N900, making executable, and running, results in error:
Code:
line 1: syntax error: word unexpected (expecting ")")
(I moved it to sbin and run it from there, in case it makes any difference.)

Also, the instructions say to use "-a 80008000" and "-e 80008000" options. Is this still valid since your uboot in the u-boot-for-power-kernel package is padded to just 0x38000 instead of 0x40000?

Does u-boot change the bootloader section of the NAND memory in N900 any way? (/dev/mtd0)

NoLo bootloader (/dev/mtd0) is not modified in no way.

This is a chainloading method to start u-boot without removing old bootloader.
NoLo loads a fake zImage kernel image which contains u-boot plus a kernel (in uImage format) and runs this image.
So NoLo really starts-up u-boot which then starts-up kernel (already loaded in memory)

Hi!
I have tested meego 1.2 and for this, i also have installed uboot. now i dont want to test meego anymore, but i dont know how i can remove uboot. can anyone help me with this problem without reflashing? as far as i know i dont have power kernel installed, its still the original kernel.

*edit*
if i try it with apt-get remove uboot-pr13 it tells me that its not installed.

with apt-cache search uboot i found 2 entries: uboot-mkimage and uboot-power-46 with the message below it:
to remove this again, "apt-get install --reinstall kernel-power kernel-power-flasher" and reboot. does it mean that i have the power kernel installed? should i try this command? and whats the power kernel? Sorry for my stupid questions

*edit* if i enter the mentioned command, it tells me that after it 10mb of additional space will be used. sounds strange to me. please help!

I've been trying to do this with the power46wl kernel but the device never boots. It shows the little penguin, u-boot times out, the correct kernel is shown, it says linux kernel uncompressed the size and all that but it stays on "loading kernel" forever. I tried both matan's u-boot and one I compiled myself with the instructions here http://elektranox.org/n900/kernel/uboot.html and also the method mentioned in this thread and the builder.py in the link but nothing works. Has anyone made the combined u-boot+power46wl image and can share it?
