iMX50 SD Boot Issue

Hello all,
I am having an issue writing and booting Ubuntu 10.04 to the iMX50. The issue is that the iMX50 will not boot from an SD card. The process I am following is:

Connect the iMX50 platform to a Windows 7 computer via mini B connection in bootloader mode
Using mfgTool.exe to write the image to the card through the iMX50 platform USB HID mode (This process returns no errors)
Turning off the board, changing dip switch positions to enable SD1 boot
Turning on the board, connected through a Putty serial session
If I let the board autoboot , the last command echo'd to Putty is "FEC: enable RMII gasket" and putty no longer accepts input
If i abort autoboot, I run the following commands

RD3 U-Boot > setenv bootargs_mmc 'setenv bootargs ${bootargs} console=tty0 root=/dev/mmcblk0p1 rootwait rw'

RD3 U-Boot > setenv bootcmd_mmc 'run bootargs_base bootargs_mmc;mmc read 0 ${loadaddr} 0x800 0x1800;bootm'

RD3 U-Boot > setenv bootcmd 'run bootcmd_mmc'

7. Running bootm after this then returns

ERROR: can't get kernel image!

Any suggestions on how to fix this problem would be much appreciated

Thanks in advance,
Andrew
