I’ll look at making another entry. There is nothing to implement on your end. It draws a white box around the border of the frame buffer and fills it with 16 bars. It is imperative that these base-ceiling pairs match up when the hardware reads them. Added by Otmar Schlunk over 8 years ago. Now we move on to installing the LCD panel the one we got from you and trying to get that working. Schlunk, The kernel included in the development kit provided should have the necessary code installed to support either the DVI interface or the LCD panel interface.

Yes, the instructions are involved, but they’re easy enough to follow. We’ll need to post the configuration instructions and the respective FPGA images with code, so you can merge this with you custom IP. From Texas Instruments Wiki. That’s the right image. In this case, a video display framebuffer must be available at the start daa8xx-fb for every ISR.
I now see a raster on the DVI-based monitor. For some reason, I had copied the instructions for the Rev. What I mean is that the pixels are in the right places. Sorry for the delay.

A few oddities, but I’m now able to at least talk to the frame buffer. Here’s what I see: I’ll post the LCD image up there. Also describes root cause and its solution. We’ll take a look at this setup today and let you know what happens.
At this point, all we really need to do is draw a bitmap to memory and have it show up on the LCD. Is the text white you may need to poke the blank variable as mentioned above.
If you know which path you’d like to head down I’ll dax8x-fb to add that information first. Quite possibly an error on my end.

It will lead to sync error interrupts and possibly affect system performance. Otherwise, we’ll lfd you again when we have questions. All the files show up at the bottom of the wiki.
Software can make use of this register to set the requestor priorities for required EMIF arbitration. My logo is grayscale on a white background, and the background is blue could be blue-green; I didn’t check that closely.
Any recent changes to that? Retrieved from da8x-xfb http: Do you have a specific tool you know about for converting to RGB format? And it is expected to feed the filled buffer on every frame done callback.
The screen is all blue and green. If so, let me know. Are we setting some environment variable here? You punched in the i2c commands for the Rev C board.
It draws a white box around the border of the frame buffer and fills it with 16 bars. I’m researching that now and will post here again if I find it before someone else does.

The kernel included in the development kit provided should have the necessary code installed to support either da8xxfb DVI interface or the LCD panel interface. Then trim off the first 72 bytes of the file. If not, can you tell me how to create them?
