Nokia N900 on 5.4 and 5.5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I've tried to build 5.4.18 and 5.5.2 for the Nokia N900, using
omap2plus_defconfig. Using appended DTB, like so:

$ cat arch/arm/boot/zImage arch/arm/boot/dts/omap3-n900.dtb > zImage.dtb
$ mkimage -A arm -O linux -T kernel -C none -a 80008000 -e 80008000 -n
zImage -d zImage.dtb uImage

But they both fail to boot for me - the device resets almost instantly:

Full log below. I tried the same with "-Os" instead of "-O2" ; to no avail.

Any clue what could be up?

Cheers,
