Just got a imx6-sdp board and booted it up. I had been working with the -sdb board and noticed the new one's u-boot environment was a bit different. My BSP/u-boot experience isn't that great, and would like to know if there's a good run down on the differences. I noticed the use of a booti command which I've never seen before. I imagine this is specific to how the image is set up. Is my thinking correct?
