When the NFS server tells "insecure" in this context it practically means "I'm not sure that the request comes from someone who has root access to their machine" because even non-root Regards, robert Balau 2010/05/11 The insecure option allows to use IP ports that are above 1024. vmlinux) always have one of these archives embedded in them. Kernel images (i.e.

I expect that uImage does not know how to proceed on. It works. * If you add the host address: "-net user,net=192.168.1.0/24,host=192.168.1.123" - it sets the network of the guest to 192.168.1.*, and also the host address (as the guest sees it) I had to enable stand alone shell in busybox. So I am doubtful that it is a board issue.

I am going back to building the busybox and trtying the new approach. From: Henry Nestler - 2009-07-07 09:22:50 H. For higher version, QEMU stopped at "Uncompressing Linux …". switch_root Unlike initrd's /linuxrc, which used pivot_root1 and umount when switching to another root device, initramfs' /init uses switch_root to achieve this.

The "nfsroot" kernel option is used to indicate the IP of the NFS server. Try also appending earlyprintk=serial and debug parameters to the kernel to see if it prints something else.

Kernel panic - not syncing: No init found. Check This Out It seems that Dwi Sasongko S got a console anyway afterward.

In case of initramfs, that is when /init is executed and it is mounted explicitly; in case of non-initramfs, it is mounted just after / is mounted and before /sbin/init is Run usr/gen_init_cpio with no arguments for a full description of the file's format.

I notice that '/dev' is not populated (except by the items I created with mknod); shouldn't udev have done its magic?

-S. How does the uImage start the initialization run? You could launch QEMU with "init=/bin/sh" instead of "init=/sbin/init" inside the "-append" option. Try also to add the line "#!/bin/sh" at the beginning of rcS. Chai 2011/03/10 Hi Balau, Your tutorials are very intriguing .

I don't think root, nsfroot, ip and rinit options are the problem because the kernel is not giving you any messages from the beginning; although I don't understand rdinit without providing Check out the explanation in Section Helloworld Example: Additional Notes for a trivial example of this mechanism in action. done, booting the kernel.
