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:

  1. Connect the iMX50 platform to a Windows 7 computer via mini B connection in bootloader mode
  2. Using mfgTool.exe to write the image to the card through the iMX50 platform USB HID mode (This process returns no errors)
  3. Turning off the board, changing dip switch positions to enable SD1 boot
  4. Turning on the board, connected through a Putty serial session
  5. If I let the board autoboot , the last command echo'd to Putty is "FEC: enable RMII gasket" and putty no longer accepts input
  6. 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
