Hi，
When I follow the steps provide by quick start guide, the serial port print the information as below, the linux for LCDK hasn't come up rightly. I guess the problem maybe that "reading boot.scr ** Unable to read "boot.scr" from mmc 0:1". I use the Sdcard attached and havn't changed anything. So what's the problem about. Thank you for you help.
