Failed to execute /linuxrc. Attempting defaults...
Hi,
I am transplanting a linux kernel(edition:2.6.22.6 ) to S3C2440(cpu,sumsung, arm9)and I download the kernel and a filesystem of yaffs2 into it,and print following messege: ##### 100ask Bootloader for OpenJTAG ##### [n] Download u-boot to Nand Flash [k] Download Linux kernel uImage [j] Download root_jffs2 image [y] Download root_yaffs image [d] Download to SDRAM & Run [z] Download zImage into RAM [g] Boot linux from RAM [f] Format the Nand Flash [s] Set the boot parameters [b] Boot the system [r] Reboot u-boot [q] Quit from menu Enter your selection: b Booting Linux ...

Freeing init memory: 132K Failed to execute /linuxrc. Attempting defaults... Kernel panic - not syncing: No init found. Try passing init= option to kernel. Note: The filesystem has a link file linuxrc and it is executable,the linuxrc is link to busybox in /bin . can some give me some tips or suggestion? DW Wang |
