SAMA5D4 and my Ubuntu experience. Blog Post #2 - A place in the cloud

14 Apr 2015

Over the weekend just gone by I managed to create an Ubuntu boot disk and get the SAMA5D4 running with an operating system that provides me with

features I am a little more used to vs the Poky build that Atmel provide.

What I built was Ubuntu 14.04.1 LTS compiled and running on the SAMA5D4 Xplained Ultra board. Along with supporting root file system.

Thankfully this include apt-get and I have been able to install all my favourite tools, including a GCC compiler tool chain directly to the

board. I really enjoying developing directly on single board computers so this is pretty useful for me.

I used a lot of web references to help me along my journey.

Prior to visiting the site below I set up an Ubuntu virtual machine, installed the Ubuntu kernel source and installed the gnu toolchain cross

compiler for ARM. That was all without references and actually managed to create a zImage file in a little under an hour. Most of the time

was spent downloading the AT91 source code.

The most useful site which gave me a lot of clues was the page for Robert Nelsons EEWIKI website that contains the info for the SAMA5D4EK.

Prior to finding that site I was a bit hooked up on the boot manager and couldn't make it work terribly well.

So his U-BOOT section was a great guide into getting things rolling a little more smoothly.

I could only get so far in the process until it hung and would go no further.

I won't replicate his site here as the steps are quite easily to follow and I've been through his entire process and got it working as well.

The process is quite lengthy though if you want to build your own kernel image, put a couple of hours aside to do it.

One of the most important files to modify was uEnv.txt

It contains a large number of boot parameters, but one line in particular was very important in getting this board up and running.

It was the primary board identifier for the device tree.

you have to make sure you include the line

fdt_file=/dtbs/at91-sama5d4_xplained_hdmi.dtb

You don't necessarily need to use the hdmi device tree, but it will add the framebuffer to /dev for you, which means you can tinker

with getting the HDMI screen running. I admit I have had it working, but not as a console display its not easily plumbed into place like on a Raspberry Pi.

I managed to draw a lot of colourful pixels to it using the command cat /dev/urandom > /dev/fb0

I found I needed to sometimes plug and unplug the HDMI cable to make it recognize the monitor was there.

Now that i have Ubuntu on the board I'll be able to continue with my project and install RabbitMQ, as this will be the crux of my message bus/handler for

my IoT cloud based edge router and it will be processing all the data from my IoT devices.

If you would like to get hold of the Ubuntu image I created, you can download it from Dropbox.

It's designed to fit onto an 8GB SD card. Just use your favourite image burning software to burn it to the card.

On Windows I use Win32 Disk Imager for Ubuntu, dd also works just fine.

I've been learning about U-Boot this week too. That's what is used on the Linino side of the Arduino YUN, I needed to use it to reflash the OS image via TFTP when I managed to pull the power half way through flashing it from the SDCard.

Hi Andy,
thats good to know. Yun will be next cab off the rank for me I think.
Looking forward to giving it a go and seeing what mischief I can get up to.

Did you manage to recover after your dropped power mid way through the flash?

The Yun would not boot with the half installed OS, the "press a button for 30s" trick to reinstall the default did not work either, I'm guessing that those buttons are soft keys. So using the Arduino - YunSerialTerminal script and this warranty voiding process Arduino - YunUBootReflash I got it back and operational again, I'm currently running with a Linino version so get a friendly robot on my admin screen rather than Arduino Logo.

If I have time I'll be looking at the boot process in more detail as I'd like to get the boot time down from 41s. I'm hoping to be able to turn off that part of the board and restart it periodically to check the weather before shutting it down again. There seems to be some big pauses in the boot sequence. The idea is to run it all from batteries and have the board sleeping most of the time.

I'm also wondering if I can customise the default admin page but again that's at the end of my challenge when everything else is working correctly.

Here's my boot log.
