How to boot imx using ramdisk

21 minute read

This post explains how to load a ramdisk on iMX boards. The initrd and initramfs are two ways for achieving this. This tutorial approaches only the initrd (initial ram disk) method. This guide uses iMX6Q Sabre SD Board, and uses a file system generated by Buildroot.

Follow the next steps to enable the Kernel to support initrd:

$ make menuconfig

Then, mark the following packages in General setup:

  • Initial RAM filesystem and RAM disk (initramfs/initrd) support
  • Support initial ramdisk/ramfs compressed using gzip.

Compile the Kernel:

$ make

For building the initrd on Buildroot file system, follow the next steps:

$ git clone git clone git://git.buildroot.net/buildroot
$ cd buildroot/
$ make imx6-sabresd_defconfig
$ make menuconfig

Then, mark the following option:

  • File system > initial RAM filesystem linked into linux kernel

Compile the file system:

$ make

The result of this compilation is a rootfs.ext2.gz file.

For converting the file system to the right format, it is required to use mkimage tool. To install the tool use the following command:

$ sudo apt-get install u-boot-tools

Run the following command:

$ cd output/images/
$ mkimage -A arm -O linux -T ramdisk -C gzip -n "Build Root File System" -d rootfs.ext2.gz rootfs.ext2.gz.uboot

Copy the following files to the tftp folder. In case need help to install the tftp, read this post here.

$ cp linux/arch/arm/boot/zImage /tftpboot/
$ cp linux/arch/arm/boot/dts/imx6q-sabresd.dtb /tftpboot/
$ cp buildroot/output/images/rootfs.ext2.gz.uboot /tftpboot/

The file system is ready to be loaded. In U-Boot prompt set the following environment variables:

=> setenv autoload no
=> setenv initrd_high 0xffffffff
=> setenv fdt_high 0xffffffff
=> setenv loadkernel 'tftp 0x10000000 zImage'
=> setenv loadinitrd 'tftp 0x12800000 rootfs.ext2.gz.uboot; setenv initrd_size ${filesize}'
=> setenv loadfdt 'tftp 0x13f80000 imx6q-sabresd.dtb'
=> setenv bootargs 'console=ttymxc0,115200n8 root=/dev/ram0 rw ip=dhcp'
=> setenv bootcmd 'dhcp; setenv serverip YOUR_TFTP_IP; run loadkernel; run loadinitrd; run loadfdt; bootz 0x10000000 0x12800000 0x13f80000'

After these environment variables are set, run the following command:

=> run bootcmd

The kernel, dtb and rootfs will be downloaded by tftp and loaded into memory.

Below, follows the board booting:
