Good morning, i solved my problem last problem and now i get console output. :) So next step is to setup the root file system. I want to use an image loaded into ramdisk, but seems i?m missing something. I?m using u-boot to load the ramdisk and linux kernel. Actually i don?t know how the kernel gets the location of the loaded ramdisk. I only added the support (see Kernel configuration) and the command line parameter root=/dev/ram rw. But the boot command arguments from u-boot seems not recognized from the linux kernel. Should the option CONFIG_BOOT_LOAD point on the address of the ramdisk? I hope someone could help me to trigger out my problem.
Thanks and Best regards, David Console output: ## Booting image at ff000000 ...
