Hi,
Now i'm working on imx7d sabre board and hdmi<->vga converter.
And i made kernel, uboot, rootfs using buildroot latest version.
(first i used defconfig on buildroot
kernel - 4.1.15, uboot - 2016.1, cross compiler - gcc linaro 6.2.1)
But i could not work on hdmi display.
Please feel free to help me...
