Hi, I have a new development board with 32 Go. (ls2088ardb rev f). U-Boot works well. I have the same error as Kepler2, when I try to connect to the target I got DDR error in the init script. The files provided by ufedor (in the zip files) are the same as the ones that I have in /opt/Freescale... But I do not have the the same RCW and I did what you suggest, dump registers, and nothing are similar.
