Return to Question

Linux 2.6.26.5 embedded. I need manually mount the root file system from busybox shell (initramfs). Because this Linux kernel not use devtmpfs, I have to create the basic device nodes manually, use mknod (/dev/null, /dev/zero, dev/mtdblock {0-10}, ttys). I'm not sure about correct format for /dev/mtdblock and ttys. Should I create nodes for both /dev/mtdblock and /dev/mtd? The device creates 11 MTD partitions on nand0. Where to find the major and minor numbers assigned for a devices? The same question for ttys: what is correct mknod command for 5 /dev/tty and 4 tty - are they in different places?

mknod /dev/ttyS0 c 4 64 mknod /dev/ttyS1 c 4 65

For example:

mknod /dev/mtdblock0 b 31 0 ... mknod /dev/mtdblock10 b 31 10 mknod /dev/mtd0 c 90 0 ... mknod /dev/mtd10 c 90 20 

And where to get the major and minor numbers assigned for a devices? The same question for ttys, where to find ttys # and major and minor numbers?

mknod /dev/ttyS0 c 4 64 mknod /dev/ttyS1 c 4 65
