Hi,

In the boot.scr and user.scr for the angstrom validation image I have
tried several permutations of:
setenv dvimode 1280x1024MR-16@60
setenv dvimode 1280x1024MR-24@60
setenv dvimode 1280x1024MR-32@60
setenv dvimode 1024x768MR-16@60
setenv dvimode 1024x768MR-24@60
setenv dvimode 1024x768MR-32@60

but each one of them returns me to a 640x480 screen.

Only setenv dvimode hd720 gives me the correct result so far.

Has the syntax been updated for this, and if so where can I find out
about it?

The above looks right to me. I suspect some other u-boot challenge.
Can you include the entire serial log?

Has the syntax been updated for this, and if so where can I find out
about it?

You can find out about it in the kernel documentation[1], but I don't
think it has changed.

Thanks, can see issues with boot process finding the resolution, not
sure how I should resolve this though:

Noticed that hd720 gives the same couldn't open module errors, but
falls back to 1280x720 as default. Confused.

5

drivers/video/modedb.c?

KP

6

Looking at that I appear to be using the right syntax in the boot
scripts.

7

I don't see a problem with the detection, so I don't know what you are trying to say or what you are seeing as the behavior. I was asking for a complete log, not just the X startup. Clearly you are specifying 640x480 as the resolution in the boot sequence.

8

Sorry, showing my lack of linux knowledge - I don't have a serial
cable to hand, and don't know how to setup serial log saved to within
linux if that is possible?
Totally understand if you are unable to answer the following due to my
lack of testing with serial cable.

I assume there is somewhere else I need to specify the resolution as
above apart from the boot.scr and user.scr for the Angstrom
distribution? The setting of hd720 does work giving a resolution of
1280x720, only the options listed in the first post don't work. There
is also no option in Angstrom's monitor properties to specify other
resolutions other than the two that do work - hd720 and 640x480. It
finds the monitor as 'unknown'.

Is there somewhere else I should also be specifying the resolution in
this syntax:
omapfb.mode=dvi: 1280x1024MR-24@60

That's the wrong syntax (one space too many).

setenv dvimode 1280x1024MR-24@60

Sorry, but the second example in my first post is exactly the same as
that and this:

http://groups.google.com/group/beagleboard/browse_thread/thread/cb03f0a25b36a8d7/881028e9479491a9?show_docid=881028e9479491a9&fwc=1&safe=active&pli=1

Will try again this weekend, but am sure I have copied your previous
post exactly.

11

PS, I am using the following image:

http://beagleboard-validation.s3.amazonaws.com/deploy/201008201549/sd/beagleboard-demo-201008201549-configured.img.gz

That is the most recent image and won't cause any problems with
1280x1024? I ask because I've noticed the onboard sound doesn't appear
to work, but assume that is because OSS/ALSA is not setup properly.

12

That image should not make a difference for the resolution...

Starting from the beginning, print out your boot.scr... (ignore the
unreadable header crap)

Next how are you changing the resolution? in the boot.scr?

Regards,

13

Thanks - will copy the boot.scr later. I changed only the setenv
dvimode line in both the boot.scr and user.scr to both the same value.

14

Kernel command line: console=ttyS2,115200n8 mpurate=1000 buddy=none
camera=lbcm3m1 vram=12M omapfb.mode=dvi:640x480MR-16@60

so, why are you so surprised to see 640x480? :slight_smile:

Find a serial cable and set the desired resolution in u-boot.

BTW guys, is it difficult to enable resolution change right from running linux? I tried xrandr with no luck

2010/9/16 lchile <beaufortscale@gmail.com>

15

the dss2 stuff that sets the resolution isn't xrandr aware yet and
can't be changed on the fly**.. (** that i know off..)

So till those patches appear**, setting it at boot time with
boot.scr's is the only way..

Regards,

16

Because I get 1280x720 from setenv dvimode hd720.

OK - resigned to the fact that changing the resolution properly is
only possible via the serial terminal, thanks.

17

the 'boot.scr' can be changed from a booted beagle too with mkimage...

copy boot.scr to boot.cmd remove the uboot header, edit the resolution
then rerun mkimage to regenerate the boot.scr and reboot...

Regards,

18

Ah, I thought I could edit the boot.scr and user.scr directly with
nano. Changing the offending line from 1280x1024MR-24@60 back to hd720
again gave the correct resolution.

19

Sorry - I meant using nano hd720 was re-corrected, never got
1280x1024.

20

Why don’t you use serial through USB connection without RS-232 cables? All you need is mini-USB cable
