HI
This is a great series of articles that you have written.
“Compiling Linux kernel for QEMU ARM emulator”, worked straight away.
But Im having trouble with “Busybox for ARM on QEMU”.
The code builds OK but won’t boot the shell.
The message I get is
“Root-NFS: No NFS server available giving up”
“VFS cannot open root device”
“Please append a correct root= boot option”
Is there a “root=” option missing from the command line in your script?
Or can you suggest why it cannot find the root filesystem?
Thanks Chris

Hi Chris. It seems that the kernel tries to mount the root through NFS. It could have something to do with the kernel configuration, in particular the CONFIG_CMDLINE option: mine contains “root=/dev/ram”, and only now I notice that I don’t mention it in my posts.
Try to use this option instead:
qemu-system-arm -M versatilepb -kernel zImage -initrd rootfs.img.gz -append "root=/dev/ram rdinit=/bin/sh"
