I built a custom initramfs on an udoo-neo using the following instructions: mkdir -p /usr/src/initramfs/{bin,dev,etc,lib,lib64,mnt/root,proc,root,sbin,sys} cp -a /dev/{null,console,tty,mmcblk0p2} /usr/src/initramfs/dev/ sudo apt-get install busybox-static cp -a /bin/busybox /usr/src/initramfs/bin/busybox My init file is: #!/bin/busybox sh # Mount the /proc and /sys filesystems. mount -t proc none /proc mount -t sysfs none /sys # Do your stuff here. echo "This script just mounts and boots the rootfs, nothing else!" # Mount the root filesystem. mount -o ro /dev/mmcblk0p2/mnt/root # Clean up. umount /proc umount /sys # Boot the real thing. exec switch_root /mnt/root /sbin/init And then I do chmod +x /usr/src/initramfs/init After setting the initramfs source file to "/usr/src/initramfs" in menuconfig, rebuilding kernel, copying it back to the SD card and rebooting, i just boot into my normal screen, and the echo message does not appear. I've checked if zImage is being written properly (it is). How can I fix this?
