Hi,

I'am in trouble with the SGX-Drivers.

I think the Modules are there:

debian@arm:~$ lsmod | grep omapl
omaplfb 12270 0
pvrsrvkm 155997 1 omaplfb
tilcdc 26543 1 omaplfb

And the gfx_check.sh says:

debian@arm:~$ ./gfx_check.sh

But if I start the Demo i have this error:

debian@arm:~$ ./OGLES2ChameleonMan
Can't open keypad input device (/dev/input/event0)
Exit message has been set to: "PVRShell: Unable to initialise EGL
".
PVRShell: EGL Error (EGL_NOT_INITIALIZED)
InitAPI failed!
PVRShell: Unable to initialise EGL

Is there anyone who can help me ?

I have no idea what the problem is.

Hi,

What Linux version are you using? Please note that this forum supports only the TI released Processor Linux SDK: software-dl.ti.com/.../index_FDS.html

First i work with the TI Processor SDK.
My RGB-LCD and the Touchscreen running.

Now i try to run a DebianFS with the SGX-Drivers on the BeagleBone Black.
I have build a Kernel with the SGX-Patches from RobertCNelson. And build the Grafik-SDK against the kernel.

If i have a DeviceTree with HDMI everything works fine.
But if i use the RGB-LCD i have the errors.

Now I search somebody who know what the different between "hdmi {..}" and "panel{...}".

Hi,

now I know my Problem. I use my own Panel with 24bpp. But the bufferclass_ti knows just 18bpp and 32bpp.

<code>

if(psLINFBInfo->var.bits_per_pixel == 16)
{
if((psLINFBInfo->var.red.length == 5) &&
(psLINFBInfo->var.green.length == 6) &&
(psLINFBInfo->var.blue.length == 5) &&
(psLINFBInfo->var.red.offset == 11) &&
(psLINFBInfo->var.green.offset == 5) &&
(psLINFBInfo->var.blue.offset == 0) &&
(psLINFBInfo->var.red.msb_right == 0))
{
psPVRFBInfo->ePixelFormat = PVRSRV_PIXEL_FORMAT_RGB565;
}
else
{
printk(KERN_INFO DRIVER_PREFIX ": %s: Device %u: Unknown FB format\n", __FUNCTION__, uiFBDevID);
}
}
else if(psLINFBInfo->var.bits_per_pixel == 32)
{
if((psLINFBInfo->var.red.length == 8) &&
(psLINFBInfo->var.green.length == 8) &&
(psLINFBInfo->var.blue.length == 8) &&
(psLINFBInfo->var.red.offset == 16) &&
(psLINFBInfo->var.green.offset == 8) &&
(psLINFBInfo->var.blue.offset == 0) &&
(psLINFBInfo->var.red.msb_right == 0))
{
psPVRFBInfo->ePixelFormat = PVRSRV_PIXEL_FORMAT_ARGB8888;
}
else
{
printk(KERN_INFO DRIVER_PREFIX ": %s: Device %u: Unknown FB format\n", __FUNCTION__, uiFBDevID);
}
}
else
{
printk(KERN_INFO DRIVER_PREFIX ": %s: Device %u: Unknown FB format\n", __FUNCTION__, uiFBDevID);
}

In which Files I need to make changes to support 24bpp?

Hello Michael,

You should be able to fetch the lcd config settings from the device tree blob.
Please see this guide.

Best regards,
Kemal

Hi,

yes i know that I set everything in the DTB. But if is set bpp to 24 then I get this error on the device start.

omaplfb: OMAPLFBInitFBDev: Device 0: Unknown FB format

In the previous post I explained where the error location.

Indeed, I saw it now. You have only the 16 bpp and 32 bpp. Seems the 24 bpp is not supported by this driver. Try to switch to 16 bpp or use the latest drivers where the 24 bpp is supported.
