DA8XX-FB LCD DRIVER

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. You punched in the i2c commands for the Rev C board. Views Read View source View history. To enable the display, the config options in uBoot must be updated to tell the kernel to initialize the device. When can we expect to receive feedback on this issue? We'll take a look at this setup today and let you know what happens. If you know which path you'd like to head down I'll try to add that information first.

I've got a true DVI panel hooked to the unit, as required. I'll need a little more information about the uboot to be able to have it tell the kernel to initialize the device. If so, let me know. There is nothing to implement on your end.

You have 0x3f programmed into position 0x This table defines the size of the panel as well as the desired pixel clock rate, front and back porches, etc. Can you lcr confirm the revision of your board B, or C? All the files show up at the bottom of the wiki. We'll need to post the configuration instructions and the respective FPGA images with code, so you can merge this with you custom IP.

[PATCH] davinci: fb: Frame Buffer driver for TI DA8xx/OMAP-L1xx

If ocd have designed your own hardware using a new LCD, I'm afraid you're going to be on your own to get it functioning unless you can provide schematics, your FPGA code, and some hardware for us to support you with. If you know which path you'd like to head down I'll try to add that information first. It's a work in progress, but there should be enough info in there now to at least force a frame buffer device into existence for the kernel. What I mean is that the pixels are in the right places.

The screen is all blue and green. Then trim off the first 72 bytes of the file. We'll be using it for our demo next week.

If you use qt-embedded, it has a translator built in to read png's, etc. Also we note that frames are displayed with delay of one frame period, which is may not acceptable to the user. This framebuffer, as understood by the DMA engine, will be way off. This page was last modified on 26 Septemberat You also need to load an additional module for the touchscreen controller on the LCD.

It will lead to sync error interrupts and possibly affect system performance.

Are we setting some environment variable here? Any recent changes to that?

Since we're ,cd getting any red guns, no white pixels. The LCD configuration wiki page has been started that will cover the information you need. That seems to have gotten the low-level hardware to recognize things, since the U-Boot startup now says something like "configured LCD: But Android is designed to work with double buffered mode and increasing no. A few oddities, but I'm now able to da8xd-fb least talk to the frame buffer. I've updated the wiki with more instructions they seem involved, but it's not that bad once you do it the first timeprimarily with turning on the DVI controller it comes up in a power savings mode.

OK -- we're lcs making progress here. Linux frame buffer driver uses 2 DDR frame buffers as ping pong buffers.
