Adding xM C Support to the Froyo 2.2 source... #100

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
This is basically a patch that merge's all the mainline detection's for the 
beagle xM along with the new xM C. (usb bus power is inverted so the old 
detection won't work)..

Froyo patch:

Just the kernel patch from board-omap3beagle.c is not enough. Make sure to also 
run the latest MLO and u-boot.bin if you're on a BeagleBoard-xM rev C board.

Till git bits get updated, here's the location of the MLO/u-boot.bin I'm using:

http://rcn-ee.net/deb/tools/MLO/MLO-beagleboard-1.5.0+r22+gitrb6bbfe7848de547b64
edf1c363c86cec4921b517-r22

http://rcn-ee.net/deb/tools/UBOOT/u-boot-beagleboard-2011.02+r75+gitrc7977858dcf
1f656cbe91ea0dc3cb9139c6a8cc8-r75.bin

From Angstrom's stable tree.  If you use this u-boot.bin, it does have a slight 
change in bootup, it looks for uEnv.txt vs the older boot.scr.. Here's a simple 
way to go back to boot.scr's if you don't like the new method..

Hello Sir,

I am trying to port DVSDK-4.01 onto Rev C.
I tired to use the MLO and u-boot.bin file given above for booting DVSDK-4.01, 
Now DVSDK is booting on beagleboard-xM Rev C, USB is working. 

but i am facing CMEM Error. As specified below

CMEMK module: built on Sep  4 2011 at 07:12:09

I have attached my boot-arguments, logfile, Error file.

Sir, when i read about this error in forums people suggested to change the 
boot-arguments value [i.e rdaddr=0x81000000 to rdaddr=0x81600000]. I tired to 
change but the error remains the same.

Can you please suggest me how to solve this error?
Sir, can you please share the source code of U-boot.bin that you have generated.

Thank-you,
Naveen Kumar.S
