When you leave the speed off it leaves the console at whatever speed was set by u-boot. Right now the wandboard u-boot won't let you set the speed above 115200, but there's no reason for that, I have a local hack in mine that lets it go up to 1mbps (ftdi serial adapters can go even faster, I've run them at 12mbps). I'm going to be putting together new ports for building u-boot soon which will probably have the faster serial speeds in them. -- Ian
