i.MX6 - DDR3 setup

Fri, 26 Jul 2013 15:15:04 +0000

The company I work for has designed a custom i.MX6 based board and I am the guy who does the board bring-up. For me the i.MX6 platform is a very good choice as support for the hardware in u-boot and the linux kernel is quite good. So it should not be too hard to get linux running on our custom board.

But wait… as I learned from my coreboot activities – memory setup is the hardest and most importest part. The custom board has 1GB of DDR3 on it and I started to look how u-boot does the DDR setup. And there I read the term DCD – Device Configuration Data.
