Could you help me with building linux? My target is PXA255 processor. I used kernel 2.6.7. I configured with make menuconfig to use initrd ramdisk. I used boot parameters root=/dev/ram0 but I obtained the message "Unable to mount root fs on ram0" . My ram memory starts at 0xa0000000 address. In the arch/arm/boot/makefile I set INITRD_PHYS as 0xa2000000. I had to add this entry because there were not bootpImage make target for this processor. My question are:
1) Is it possible to build kernel with ramdisk for this processor and if yes how to do it?
2) Can I load ramdisk to ram memory and start the linux? Where should I load the ramdisk image. Should it be gzipped? What addressed should I use?
