Kit Notes

iMX233-OLinuXino-Micro:
From: PDF Manual
Important note about owners of revision B of the board: if you are one of the first owners of iMX233-OLinuXino-Micro and you experience random hang-ups (Kernel oops, Kernel panic) it is recommended to unsolder/remove R17 (check the schematic or the board file to locate it easier). Removing R17 fixes the random lock-up.
This problem has been fixed in revision B1 of the board.

Vendor Documentation

Basic Requirements

ARM Cross Compiler: GCC

This is a pre-built (64bit) version of Linaro GCC that runs on generic linux, sorry (32bit) x86 users, it's time to upgrade...
Download/Extract:

Test Cross Compiler:

Bootloader: U-Boot

Das U-Boot – the Universal Boot Loader: http://www.denx.de/wiki/U-Boot
eewiki.net patch archive: https://github.com/eewiki/u-boot-patches

Linux Kernel

This script will build the kernel, modules, device tree binaries and copy them to the deploy directory.

Setup microSD card

For these instruction we are assuming, DISK=/dev/mmcblk0, lsblk is very useful for determining the device id.

Erase partition table/labels on microSD card:

Create Partition Layout:
With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.

sfdisk >= 2.26.x
sfdisk <= 2.25.x

Install Bootloader:

~/

Format Partition:
With mkfs.ext4 1.43, we need to make sure metadata_csum and 64bit are disabled.
As U-Boot CAN NOT currently handle reading files with these newer ext4 options and so Debian 8 (armel/armhf) and Ubuntu 16.04 (armhf) fsck tools will operate correctly.

mkfs.ext4 -V
mkfs.ext4 >= 1.43
mkfs.ext4 <= 1.42

Mount Partition:
On most systems these partitions may will be auto-mounted...

Install Kernel and Root File System

To help new users, since the kernel version can change on a daily basis. The kernel building scripts listed on this page will now give you a hint of what kernel version was built.

Copy and paste that "export kernel_version=4.X.Y-Z" exactly as shown in your own build/desktop environment and hit enter to create an environment variable to be used later.

Copy Root File System

Set uname_r in /boot/uEnv.txt
