Hello,
Hi,
I'm trying to enable framebuffer support to produce a splash image in u-boot for a custom image I want displayed. The idea, for now, is to simply display the splash image to a monitor running off the DVI port on the babbage. I'm fairly new to all things u-boot, just started digging through the docs and source as of yesterday, so I was hoping someone could point me in the right direction.
Looking at the README it seems I can enable splash screen and video support with a define in /include/configs/mx51_bbg.h (working with Freescale's BSP).
There is at the moment no video driver for the MX.51 on the u-boot mainline. I am not sure about the Freescale's BSP, but as far as I know there is no support for the MX51's IPUv3. But I could be wrong, ask Freescale for confirm.
However, on this ML you can find issues regarding the u-boot mainline. The "babbage" board is renamed on u-boot mainline as "imx51evk", because this is the name you find now for this board on the Freescale's website. If you have developed something that is not yet provided, feel free to send patches and to contribute to the project.
Related to the MX.51 framebuffer support, I am working on the same issue. I have ported the Freescale's Linux driver to u-boot, and at least it is working, but I am not yet ready to send patches. I am still cleaning up code and reducing functionalities, as the IPU supports much more as only a framebuffer. Of course, providing patches is on my TODO list, and I hope I can send them soon...
It builds with with the '#define CONFIG_SPLASH_SCREEN', but when I include CONFIG_VIDEO it bombs due to an undefined reference (drv_video_init) which I'm not backtracking.
I think there is no support for i.MX51's framebuffer at all, as well as in u-boot mainline....;-(
