[Buildroot] setting a driver in directfb through buildroot

[Buildroot] setting a driver in directfb through buildroot

[anthony henderson]

Hi all,
I hope someone can help me out on this.
I've compiled my rootfs in build root with directfb set.  I'm using a cirrus
logic FB93xx, which as far as I can see it has a driver.  I can't see any
way of setting the driver in make menuconfig.  I can however see in the
directory buildroot/package/directfb a file called config.in.  Can I set
here?  If so can anyone tell me what to put in for the EP93XX driver, I
can't find anything documented?  I have tried setting from my ARM system
using the directfb-config  with
directfb-config --graphics=ep93xx.  This doesn't work.  I just says driver
none.

I think I need the correct driver as directfb examples are crashing with
directfbcreate(&dfb) initialization error!

Thanks in advace :)

I've cooked the attached patch to allow a Buildroot option to enable
the DirectFB ep9x driver. Could you apply the patch to Buildroot, enable
the BR2_PACKAGE_DIRECTFB_EP9X option, and rebuild ?

Note: I haven't tested the patch, so it may not work.

Regards,

Thomas

[Buildroot] setting a driver in directfb through buildroot

Thankyou Thomas,  the patch adds the driver to the menucofig, however I
still can't get directfb or sdl to work.  I'll keep on test and try to find
out why.

Well, I don't have any hardware to test the driver, therefore I have
absolutely no idea whether the driver works or not. If you're sure that
your DirectFB configuration and your kernel configuration are correct,
then you could ask the DirectFB developers directly.

Best regards,

Thomas
