Hi Pali,

I had to comment "return -ENOSPC;" in video-uclass.c because without it DM_VIDEO does not work and I do not know why. This looks like either false-positive test or a bug in DM_VIDEO code. I have already set PRE_RELOC flag but it has no effect on that code.
Probably the frame buffer memory allocation did not work. Could you please try with a bind callback, i.e.:
static int rx51_video_bind(struct udevice *dev) { struct video_uc_plat *plat = dev_get_uclass_plat(dev);
plat->size = 800 * 480 * 2; return 0; } ... U_BOOT_DRIVER(rx51_video) = { .name = "rx51_video", .id = UCLASS_VIDEO, .bind = rx51_video_bind, .probe = rx51_video_probe, .flags = DM_FLAG_PRE_RELOC, };
Second thing is that CONFIG_VIDEO_LOGO is broken and does not work even it is enabled in config file. I do not know why too.
Any idea?
Not yet. There were some logo related changes recently, but if I remember correctly, I tested them on wandboard and nitrogen6q targets and with sandbox, and logo drawing worked there.
