I use four 4Gb DDR3 chip for imx6q. Therefore, I have 2GB memory totally. Now I want to use only 1GB memory . and delete two DDR3 chips. Besides, using 32 bit data bus. Anyone can give me a flash_header.S file that I can use directly.
Here you need to do reconfiguration DDR3, you can use the DRAM Register Programming aid in our community.
DRAM Customization on i.MX6x can do help for you.
Have a nice day
