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. ...
In some rare cases I need to debug some networking protocols and my target of interest is NTP. I am debugging an issue where (maybe) NTP sets the current time backwards about two hours.
