[U-Boot-Users] Booting problems for Integrator/CP+ARM920T

[Alan Casey]

Hi,

  I have an ARM Integrator/CP board(s) which
  contains an ARM920T macrocell. I have been
  trying to use U-Boot(1.1.2) to boot 
  linux2.6.9 (with a patch applied from ARM's
  website) on this system. As i understand it, 
  U-Boot only supports the ARM926EJS macrocell
  as the default configuration with the 
  Integrator/CP but i was hoping the same boot 
  process would work with the ARM920T macrocell??

  The default kernel command string i use when
  compiling/building/installing the kernel is:
  CONFIG_CMDLINE="root=/dev/ram0 video=vc:1-2clcdfb console=ttyAMA0 mem=128M
  ramdisk_size=17408 initrd=0x24500000,6980391"

  I then generate the kernel image using:
  arm-linux-objcopy -O binary -R .note -R .comment
                    -S vmlinux linux-2.6.9.bin
  mkimage -n '2.6.9 Kernel Image' -A arm -O linux -T kernel 
          -C none -a 0x7fc0 -e 0x7fc0 
          -d linux-2.6.9.bin linux-2.6.9.img

  I also generate a RAMDisk image in a similar way.

  I load the U-Boot, kernel and RAMDisk images into FLASH at the
  following addresses:
    U-Boot image:  0x24000000
    kernel image:  0x242C0000
    ramdisk image: 0x24500000

  Using U-Boot i set the bootargs variable as:
     setenv bootargs root=/dev/ram0 

  However when i try to boot the kernel using 'bootm 242c0000 24500000'
  i get the following message:
    ## Booting image at 242c0000 ...
       ... 
       Load Address: 00007fc0
       Entry Point:  00007fc0
    OK
    ## Loading Ramdisk Image at 24500000 ...
       ...
       ...
       Load Address: 00000000
       Entry Point:  00000000

    Starting Kernel ...

  Then nothing - the boot process freezes.

  Does anybody know what i am doing wrong?? I have tried
  numerous things such as copying the kernel image to RAM
  and booting from there but i always get the same
  message as above. Do i have to configure and build  
  U-Boot to support the ARM920T macrocell with the 
  Integrator/CP??

  Any information greatly appreciated,
  Regards,
  Alan.
