I have built buildroot rootfs by following below steps.
git clone git://git.busybox.net/buildroot
After these steps, I got an sdcard.img image in the output directory. I flashed this image in an SD card and tried to boot IMX7 sabre development board. But the device hangs in kernel with dmesg "Starting kernel ...". It seems problem with kernel image or dts file.
Can anyone help me how to boot buildroot rootfs for sabresd IMX7 board. Thanks in Advance.
