Kirkwood in DTocalypse Land

[ebbix]

Bad eraseblocks errors should be fixed on GoFlex Net by mainstream kernel 3.8.6, 3.9-rc6 and 3.6.11-2 (not out yet) as a fix has been mainstreamed.

@Kurlon,

I'm looking for the normal dtb load addr for kirkwoods. Appreciate to know if you've already found this.

Thanks,

Maybe how it's done on cubox might help?

Why would a uImage and zimage be required?

[bodhi]

Thanks pepedog!
I was guessing to load the dtb to higher address such as 0x1900000 (somewhere after uInitrd) but there might be a preferred location for Kirkwood. Looks like Cubox guy load it at 0x1c00000. For now I'll use that, and see what happen.
I think either uImage or zimage will work with new uBoot.

zimage is not supported by u-boot AFAIK, that's why there's a uimage with a modified header for uboot. I don't know if current u-boot supports loading dtb's like that. Kurlon specifically said it needs to be appended to the kernel image and that was the main concern because if U-boot doesn't support it then EVERY kirkwood device would have to have a separate kernel.

Sweet. Wasn't aware there was even a newer U-Boot. What's the link? Or it isn't for public yet?

[bodhi]

I'm testing the GoFlex Net version right now, works fine with the non-FDT kernel 3.6.11. I'm still testing the FDT kernel. Will post it soon.

[moonman]

Well its nice to know somebody is working on it. It will definitely be easier to have dtb than update the support patch with every major kernel release.

[bodhi]

@moonman, definitely, I thought the same thing.
Status: I got it booted kernel 3.6.11 until the point where initrd (Debian) try to mount rootfs and it can't mount /dev/root. But it looks like the DTB was loaded correctly. So the problem I'm having is with the initrd.
