How to generate a new uInitrd

[visiedo]

Hi,
After installing ArchLinux I upgraded the kernel and the uBoot. The new uBoot will not boot my system with the old /boot/uInitrd from Ubit 0.6.

The system will boot without a uInitrd, therefore I removed the old uInitrd from /boot and the system starts with no problem now.

Still I wonder if there is a benefit of having a initial ram disk, and if that is the case how to generate one.

I used mkinitcpio -g but the generated uInitrd, but the uBoot complained about a "wrong format" and did not boot again.

Two main benifits, at least with ALARM are 1. you can choose the rootfs partition by label 2. automatic fsck of rootfs.

There was a thread by hydro, you can also use one i already generated in uboot updating thread linked in my signature.

you need to run this after mkinitcpio
mkimage -A arm -O linux -T ramdisk -C gzip -a 0x0 -e 0x0 -n initrd-3.12.6-2-ARCH -d ramdisk /boot/initrd-3.12.6-2-ARCH
where ramdisk is the output of mkinitcpio
feel free to change version number.

U-boot is lookinf for just "uInitrd".

I'm trying to re-create a new kernel-image under a Smileplug (mostly to have the "-y"-parameter in fsck when booting up). Here is what I'm doing (I changed the kernel-version to 3-12-6-3 from 3-12-6-1):

$this->bbcode_second_pass_code('', 'mkinitcpio -g /boot/uImage.new
mkimage -A arm -O linux -T kernel -C none -a 0x8000 -e 0x8000 -n linux-mvebu-smileplug -d /boot/uImage.new /boot/uImage.3-12-6-3
')

Both commands finish without errors, but when I try to load the new uImage from u-boot, it always gives me a "Bad Data CRC" (I tried to re-create the image more than once).

Any ideas? I didn't find a how-to to generate the uImage, can somebody point me to the build-scripts for linux-mvebu-smileplug ??

BTW: do other people feel like walking on raw eggs when installing Archlinux with a MMC-card under a Smileplug? Mine just keep spewing ext-errors, but they were not cheap cards...
