We are about to manufacture a first spin of a custom imx6ul board, based on the EVK's design. Our design differs that we have our debug port on UART3 instead of UART1 on the EVK. We need to change this in u-boot and in the Linux kernel, to be able to see that our boards are alive. How do we go about doing this?
The following files (downloaded from NXP/Freescales git) are used:
The other thing is that our hardware designer has used i.MX Pins Tool 2.0 to generate iomux config files that needs to be a part of the bulds. We would like to configure our kernel for further development, but initially set some GPIO's using u-boot. How can we do this?
Information found is for other boards and endless searching in the forums have not been succesful, please help.
