Hi all,


I followed the below two links to port linux on imx6q sabresd board

1. uboot (u-boot.imx)

2. kernel (uImage)


u-boot on the i.MX6 sabre sd platform in a few commands

Linux on the i.MX6 sabre sd platform in a few commands


But I got some issues while building uboot.git and linux.git. I will share these issues with you, please help me if you get solution.

1. uboot issues

   -> Unable to find u-boot configuration file for imx6 sabre sd board in u-boot.git source code mx6qsabresd_config

    -> u-boot.bin generated successfully using different configuration file mx6q_sabresd_config but unable to find      u-boot.imx

2. kernel issues

     -> Unable to build using this configuration imx_v6_v7_defconfig

     -> I changed configuration file to imx_v7_defconfig and kernel successfully build and uImage generated but unable to generate imx6q-sabresd.dtb

Finally I tried some thing which are working fine below as shown


1. sudo dd if=u-boot.bin of=/dev/sdc bs=1k seek=1 ; sync


Above command working fine and able to get u-boot prompt from my sabresd board platform but one message i painted with blue colour for your reference. So will you please guide me whether i am using correct configuration file or not in uboot level or Is this ok?
