Kevin Hilman is the guy that proposes what should get pulled by Linus for the next kernel.
At this stage the initial support seems to be scheduled for 2.6.39 kernel.
Good work Victor!
Victor, what is the next step?
Victor Rodriguez
HI Gaston
Thanks a lot, was my pleasure to give the Initial support.
Well the next steps for the Hawkboard are open to any one who would
like to contribute to enhance this project.That was the reason why I
gave the initial support. Now the entire kernel is free for the
hawkboard develop. I just will give my point of view of what I
consider could be good for the hawkboard like next steps
1) Use the initial support , test it and check if could be enhanced or
if there is a bug fix it. It is open source project and is not perfect
by definition
2) It is not complete support we still need to add this
* Audio (AIC31xx) - Stereo Audio Codec
It is done , but the da850.c file need to be cleaned up before the
patch could be added, we are working on this but is a hard work, you
could check this on davinci mailing list if you want to work on it :)
ALSA is a great way to develop the kernel, I have just test the
arecord and aplay modules, but there are many other modules that I
haven't tested yet, and would be great to implement on Hawkboard
The other important task to do are:
* 128MB NAND Flash (MT29F1G08ABCHC-ET)
* Video Capture (TVP5147M1) - Composite Video
* Video Display (THS8135) - VGA
* Serial ATA (Davinci does not have SATA support it will be fun :) )
* USB 2.0 (MUSB) (Host)
* USB OTG
* CpuFreq/CpuIdle/PM(Suspend-to-Ram) with RTC wakeup
Power Managment is a great framework in order to develop new ideas :).
Here is a quick link
http://processors.wiki.ti.com/index.php/OMAP-L138_Power_Consumption_Summary
There is another think that i was working on , barebox , the new
u-boot, it seems a great project , would be great to have a complete
support on barebox for Hawkboard, here is the link http://barebox.org/
That could be some thinks to develop on kernel and boat loader level.
Furthermore there are much more great ideas that you could send . I
would like to have a web page where people can share their projects,
and i really meant all the project , the description of the project on
HW and SW , the source code on some pubic repository and the test
cases, and the final results.
Here is an example of one project that I want to develop with the
Hawkboard on my free time
RF control system (based on omapl138 - hawkboard )
The idea is to develop a Radio Frequency system based on xbee
technology 802.15
(http://www.digi.com/products/wireless/point-multipoint/xbee-series1-module.jsp#overview)
with the hawkboard system, The entire system is able to process any
kind of signals coming from I2C and CAN sensors. The system has a mesh
network, and every module could work as master or slave, . Besides
ehach module is able to acquire signals, process and give the control
signal to the actuators of the plant.
This is just an idea and it is not well documented but si my major
project, besides hawkboard works perfect for this kind of control
applications. In the end everyone could make your own project but the
most important is to share the information and troubleshooting in
order to help others to spend less time developing or fixing some
problem
Hope it could helps , and again is my pleasure todo this. These are
just the things that i want to do with the hawkboard feel free to do
any thing else in order to improve this system.
Regards
Sincerely yours

If no one else has, i would take this task up.

Great Sughosh, send the patch to davinci mailing list in order to be checked
Thanks a lot for your help

Can you please point me to the git tree containing your changes. I
would like to base my changes off of your port. I checked the
linux-davinci tree, but did not see your changes there. Thanks.

The link to download the kernel
http://git.kernel.org/?p=linux/kernel/git/khilman/linux-davinci.git;a=summary
The pathes were sended to davinci mailing list, They will be on the
2.6.39. But I recommend to apply the patches by your self

I had cloned this git repository, but did not find your patches
included. I guess i will have to manually apply them on the tree. Thanks.

Ok , remember in order to compile the kernel the defconfig is
arch/arm/configs/da8xx_omapl_defconfig
There you could make menuconfig and add all the necessary change that
the patches suggest in order to enable the modules, I think I
Victor Rodriguez
to make de defconfig that to add a new config file, because of the big
discussion that was last year with that
Bye the way, Michael Williamson has sanded a series of patches in
order to clean up the da850.c file, so if it is approved I will send
the ALSA support according to the new structure.

Hi Victor,
Nice to hear from you.
Here we have already worked with RF based communication system based on Xbee module on beagleboard clone.So it will be a great chance for us , if we can join with you to implement this for hawkboard.
I can provide you the more details about what and how we implemented it.
This is just an idea and it is not well documented but si my major
project, besides hawkboard works perfect for this kind of control
applications. In the end everyone could make your own project but the
most important is to share the information and troubleshooting in
order to help others to spend less time developing or fixing some

Would love to do that, but I am a newbie, If it involves git clone, compilation, booting then I can take it up.
Thanks

Looks like 2.6.38-rc3 is shaping up for Hawkboard. Would be nice if someone could test it and give us some feedback. http://git.kernel.org/?p=linux/kernel/git/khilman/linux-davinci.git;a=shortlog
I had tested with the linux-davinci kernel which i had updated last week, along with an old ramdisk and a jffs2 rootfs. Boot went fine in both cases. I have added support for the Nand flash, and should be able to send out code for review this week.

Tested with the latest linux-davinci kernel containing Victor's patches and the angstrom ramdisk. Boot's fine.
