Booting 3.9.0-rc2 on Beaglebone ?

I'm struggling to get the latest kernel git to load on my beaglebone.

My build process is:-

$ make -j 8 ARCH=arm CROSS_COMPILE=arm-linux- distclean
$ make -j 8 ARCH=arm CROSS_COMPILE=arm-linux- omap2plus_defconfig
CONFIG_DEBUG_LL=y
CONFIG_DEBUG_OMAP2PLUS_UART=y
CONFIG_DEBUG_AM33XXUART1=y
CONFIG_EARLY_PRINTK=y
CONFIG_ARM_APPENDED_DTB=y
CONFIG_ARM_ATAG_DTB_COMPAT=y
CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_FROM_BOOTLOADER=y
$ make -j 8 ARCH=arm CROSS_COMPILE=arm-linux-
$ cat arch/arm/boot/zImage arch/arm/boot/am335x-bone.dtb > arch/arm/boot/zImage-dtb.am335x-bone
$ scripts/mkuboot.sh -A arm -O linux -C none  -T kernel -a 0x80008000 -e 0x80008000 -n 'Linux' -d arch/arm/boot/zImage-dtb.am335x-bone arch/arm/boot/uImage-dtb.am335x-bone

But this produces the following when booting:-

Please check your kernel config and/or bootloader.

I guess I'm missing some vital step ?

Thanks for any help

Hi,

We're changing the mainline kernel tree to use device tree based booting only.

So you need to either upgrade your bootloader to support device tree based booting, or enable CONFIG_ARM_APPENDED_DTB and ARM_ATAG_DTB_COMPAT in your .config and build u-image manually with the .dtb appended to the zImage. Doing make dtbs will generate you the am335x-bone.dtb to append.

Regards,

Tony
