i.MX27 device tree

Hi all,
I do need to test latest 4.1 kernel on i.MX27 PDK, but I'm not able to find any bootloader providinfg dts support.

Could you give any suggestion?

Thanks
Regards
Pierluigi

You can use Redboot to boot a mainline kernel on mx27pdk.

make imx_v4_v5_defconfig
make menuconfig

Boot options--->

then select:

[*] Use appended device tree blob to zImage (EXPERIMENTAL)
[*] Supplement the appended DTB with traditional ATAG information

Build the kernel: make
Build the dtb: make imx27-pdk.dtb

Append the dtb to the kernel:
cat arch/arm/boot/zImage arch/arm/boot/dtb/imx27_pdk.dtb > zImage_combined

Rename zImage_combined to zImage and then boot it as it were a normal zImage.

Hello Pierluigi,

U-Boot is working fine for us on our i.MX27 modules when running vanilla kernel with DT.
Configs and DTS can be find on our forge:
