Message: 57929   

Hello -

  I am currently trying to compile Links 2,0 (graphics enabled) for the BF548 EZKIT Lite.  After days of fiddling with the thing, I have gotten past linking against libpng.  (That really had me in a bind for a while.)  Now that I've gotten past that, I'm getting stuck with "config: error: No graphics drivers found."  I don't have any ideas on this one.

  If anyone has any experience building graphics enabled links for the BF548 and could point me in the right direction, it would be greatly appreciated!

Thanks in advance -

Caleb

I must be downloading the wrong file then.  I have downloaded the following:

http://blackfin.uclinux.org/gf/download/frsrelease/378/4236/linux-bf548-ezkit-2008R1-RC8

then tftp'd it to the device and ran bootelf.

Apparently, that isn't what I'm supposed to be downloading.  Should I be looking elsewhere?

Thanks -

Caleb

that is just the default image.  we dont include a lot of things in the default image as it would make it prohibitively large.

Thanks for your help, and I apologize for my delayed response.

I got the source from your website and built the kernel / vendor apps to include links.  However, when I deploy uClinux to our BF548 and try to run links in graphics-enabled mode, I receive the following error:

Any help in resolving this would be greatly appreciated.

If it isn't enabled by default, then no - I didn't enable it.  How do I enable it? (Please forgive my ignorance - I have very little experience with linux and absolutely none in building a kernel from scratch).

just look at the lcd once you've booted into linux ... if it's black, your driver isnt loaded

in that case, please review:

I must be loading it then.  I get the kernel messages, followed by the linux penguin image in the top left.  I can pipe output to /dev/tty0 and it shows up.  I can also run the /bin/video_test app and that displays on the screen as well.

you're probably building for FLAT.  make sure your local tree has this fix:

Back for round two.

Now that I've gotten graphics-enabled links working on the BF548 - I've been assigned the task of doing the same on the BF527.  I've made lots of progress, but am starting to wonder whether or not graphics-enabled links is a possibility on this device... which is why I'm here.  I don't want to spend a week trying to get it to work if it's not supported.  Which leads me to my question:  is graphics-enabled links supported on the BF527 EZKIT?  Posted below is the last bit of the output I was able to capture from the device, if it's at all useful:

(*) FBDev/Mode: Preparing switch to 320x240 RGB24

(*) FBDev/Surface: Allocated 320x240 24bit RGB24 buffer at offset 0 and pitch 96

Can you check that /etc/directfbrc is installed, and seems to work OK?

Can you run the other directfb applications? or do you get the same thing?

  Thanks for the quick reply.

/etc/directfbrc is an ASCII text file containing the following:

mode=320x240

depth=24

pixelformat=RGB24

As for other directfb applications - I'm not sure.  I've been unable to build any of the directfb examples (for either device, actually) - but the canned /bin/video_test demo does work, if that's of any consequence.

You should just be able to select "DirectFB Examples", and get a bunch of things in /usr/bin

   Sadly, no, that doesn't work for me.  My build always fails when I include the DirectFB Examples for either the BF548 or BF527 devices.  If you think it would help, I can rebuild and provide you with messages from the points of failure.

Thanks again -

Hi Mike,

Do you know what exact is the limitation in DirectFB?

Is it possible the framebuffer of BF527 EZKIT to be changed to support directFB requirement (workaround the limitation)?

Regards,

Nikolay
