  1. I have built u-boot with different parameters in the .config file for several LCD panels: 800x480 and 800x600. That becomes the size of the reported uboot screen and also the Linux kernel inherits the same size. But always 32 bit, even if I put the depth=16 rather than the standard depth=18 into the configuration. My problem is not with the memory allocated internally for the FB: it's the application in the user space that needs many off the screen windows (pixel buffers, really) that have to match the ARGB FB format. Anybody?
  2. Hi, I realize that V3s is not H2 or H3, but I hope the question is generic. Is it possible to make the FB 16 bit? In mainline Linux? I'm working with a Lichee Pi board. The depth is 18 bits but the fb in Linux is 32 bit. I'd love to get it down to 16 bits to save 1/2 of the video memory and just 2 color bits are a small price to pay. I understand that Linux inherits the FB from u-boot.
