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.
