New beagleboard demo image available

mentorel · March 23, 2010, 2:47pm

Hi guys!

I connected C2 to Toshiba 1080 TV set with HDMI and try to see anything on the screen. I see nothing.

I did the following:

placed MLO, uboot and uImage marked 18-Mar-2010 from http://www.angstrom-distribution.org/demo/beagleboard/ to a SD card
so, the board boots to the Angstrom print and login prompt
placed files from Angstrom-Beagleboard-demo-image-glibc-ipk-2010.3-beagleboard.rootfs.tar.bz2 to the second partition of the SD.
set bootargs as:

console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootwait mem=99M@0x80000000 mem=128M@0x88000000 mapfb.mode=dvi:1280x720MR-16@60
then
console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootwait mem=99M@0x80000000 mem=128M@0x88000000 mapfb.mode=dvi:1360x768MR-16@60
then
console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootwait mem=99M@0x80000000 mem=128M@0x88000000 mapfb.mode=dvi:1920x1080@24

In any case I got a black screen on the TV. Can anybody suggest the solution?

regards,
Max

3) set bootargs as:

In uboot do:

nand erase 260000 20000 ; reset

and then only set resolution using 'dvimode', that avoids mistakes like spelling 'omapfb.mode' as 'mapfb.mode'.

set bootargs as:

console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootwait mem=99M@0x80000000 mem=128M@0x88000000 mapfb.mode=dvi:1280x720MR-16@60
then

Replace the
“mapfb.mode=…”
with
“omapfb.mode=dvi:1280x720MR-24@60 omapdss.def_disp=dvi”
then try it.

guys,

can you just copy here full bootargs arguments which 100% work with HDTV. I’m really stuck here

I didn’t use mapfb.mode instead of omapfb. Notebook connected to BB doesn’t have the Internet and I had to type by hands the bootargs string looking at it

The whole point is that you shouldn't be changing bootargs, but one of the helpervars instead

mentorel · March 23, 2010, 4:13pm

Koen,

can you give me an example? I want to understand everything clearly, so I would not have to ask anything from the community. May be you have some link with the description so I don’t bother you.

Also I want to understand parameters regarding video mode. Where can I read about?

Dear Koen,

is it possible to run this demo with a RAM only 128M? What parameters should I use to enable DSP and SGX 3D demos?

I have a board with DDR 128M and 256M NAND

regards,
Max

Bjoern_Krombholz · March 26, 2010, 8:13am

Yes, it is. I'm successfully running it on a B6 revision.

Just remove the "mem=128M@0x88000000" from bootargs and make sure you don't start too many processes at the same time. Especially omapfbplay seems to need a good chunk of memory.

I added a swapfile to the second partition to prevent crashing OOM situations.

I think you're confusing it with the DDK

USB keyboard is not always detected during boot up. Thanks God a mouse is well detected. A keyboard has to be physically removed and inserted back so the kernel could detect it.

Both kbd and mouse are connected to the same 4 ports USB HS hub…

Paul_Menzel · March 27, 2010, 4:21pm

I am too having problems with USB. My 4 port USB HS hub which worked
before on the BB and is working on my desktop PC and attached devices
(keyboard, mouse, USB-to-Ethernet adapter) are not working.

As I said the USB cable is not bad since it works on a different system.

I am revision C3 of the BeagleBoard.

Is that on ehci or otg?

mentorel · March 27, 2010, 4:36pm

I have these problems with EHCI

The same is true for me.

Paul_Menzel · March 28, 2010, 5:27pm

I just wanted to note that restarting the BB today with the
USB-to-Ethernet adapter directly plugged in worked. So I did `opkg
update && opkg upgrade` and this to have gotten me an updated Linux
kernel (2010.4-test I think).

My USB hub is working now.

Thanks,

Paul

mentorel · March 28, 2010, 5:56pm

So what? You just try to reboot the board 100 times in a row and then tell us the statistics. If it is OK for you to have days when the HUB works and days when it does not, good for you. For me it is a problem when you show anything to a customer and it “occasionally” stops working. “oops!” is not accepted…

Sorry, if I said something wrong. As far as I can see it works for me
now reliably after the upgrade and I wanted to notify the people
interested in this issue.

Maybe you should also experiment with different Linux version.

For me it is a problem when you show anything to a customer and it
"occasionally" stops working. "oops!" is not accepted..

You can always pay people to fix/create things and you then can make
demands if it does not work.

Sorry and good luck,

Paul

hi I have used the demo image and i would really like to thank koen. I have a small query kindly any1 help me asap.

inorder to use the dsp i had given the following boot args
setenv bootargs ‘console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootwait mem=99M@0x80000000 mem=128M@0x88000000 rootfstype=ext3 rw vram=12M omapfb.mode=dvi:1280x720MR-16@60’
is the above boot args correct.
How do i check my dsp is working or not
Is it possible to use dsp accerelated mplayer as I need to stream 4 rtsp streams and my videos are very jerky.
Im not able to copy or paste any commands onto my shell.

kindly help me asap
