Many people ask what is the situation with the Linux support on A13. Last Friday Dimitar Gamishev came to our office to show us what he did.
He uses the “community” Uboot and the Kernel from http://linux-sunxi.org/Main_Page and made boot-able SD-card with Debian and made small show to us:
you even have Gimp
browser:
Libre office:
Needless to say USB keyboard, mouse, USB-to Ethernet based on AX77882 dongles and the RTL8188CU WIFI adapters are supported, so you got small board consuming 2W with desktop perfrormance.
Unfortunately the video accelerator is not supported by the “community” Linux image as they are available only as binaries and not GPL compliant, let’s hope Allwinner will release proper GPL sources soon, they promissed this to XBMC group but it’s hard to say when this will be available.
Meantime we ran Linaro video test at @30 fps and here you can see that even without video accelerator A13 is capable to play the video without any slow down: http://www.youtube.com/watch?v=ZHMCGD59t54
With this Linux bootable SD-card you can keep your Android image in the NAND flash and experiment with Linux on A13.
What version of Debian is this? Is it Wheezy?
Wheezy is the first version of Debian to support Gtk+3 so it would be great if you got it to work!
I’ve got the armhf version of Debian Wheezy running on one. I haven’t got around to installing Gnome yet but so far its going well.
With armhf and binary video drivers, the performance should see a quantum leap for many applications.
Any plan to have Linux to boot from NAND?
yes, this is possible too, linux can boot both from sd card or nand depend on where the image is burned
Hi,
I know this is little off topic, but I thought still I’ll give it a try.
We bought your maxi board as a reference, since it pretty much hits all the sweet spots for us, except boot target..
You guys obviously know your stuff, and I hope you help me bridge a gap in my knowledge of boot process..
How should we connect flash chip itself to mx233, and make boot loader boot from it? We wouldnt mind documenting our solution for others as well, once we get it running.
There is a bit longer topic in your forums as well, where I’ve been asking these questions (imx233 bitburner): https://www.olimex.com/forum/index.php?topic=5.0
Thanks for any possible tips!
If I knew the answer I would answer directly on our forum as I saw your question there, but we never did such configuration – booting from external flash
I’m sure this is possible, but someone have to read the datasheets and experiment, also you should think for some kind of tool which to program this flash, A13 have such tool which program which can erase and re-program the flash, I’m not sure for iMX233
How should be prepared the NAND flash?
Is there a step-by-step guide?
not yet, but we will do this soon
Lori, yes it is wheezy
Great News , where is possible to download the immage for doing first test ?
Best
Roberto
yes, you can following this discussion https://www.olimex.com/forum/index.php?topic=7.15
What is the default memory split between the CPU and GPU and is there a way to change it?
I has developed an custom beagebone, i has adding VGA modul for my board follow your solution used r/2r ladder, but i thing it is not best solutions, i has test another solutions used r/2r lader and get better video graphic, if you attention on my sotution please note me by email, i want help you get better video graphic with your board, i ‘m like your board!
BTW, can’t the binary (proprietary) video drivers be used ?
Can Dimitar Gamishev make an image from his sd card and publish it so we can all see the epicnes of his work
he already did this on our forum https://www.olimex.com/forum/index.php?topic=7.0
