Here's the kernel command line: console=ttymxc0,115200 root=/dev/mmcblk2p2 rootwait rw video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB2 4,bpp=32 fbmem=28M This is the kernel version: # uname -a Linux imx6qsabresd 3.14.28-1.0.0_ga+g91cf351 #1 SMP PREEMPT Tue May 19 17:32:51 EEST 2015 armv7l GNU/Linux Here are the framebuffer devices nodes: # ls -lh /dev/fb* crw-rw---- 1 root video 29, 0 Jan 1 1970 /dev/fb0 crw-rw---- 1 root video 29, 1 Jan 1 1970 /dev/fb1 crw-rw---- 1 root video 29, 2 Jan 1 1970 /dev/fb2 crw-rw---- 1 root video 29, 3 Jan 1 1970 /dev/fb3 I can write arbitrary data on /dev/fb0 and see it on screen, like this: # cat /bin/busybox.nosuid > /dev/fb0 But I can't write to /dev/fb1: # cat /bin/busybox.nosuid > /dev/fb1 cat: write error: No space left on device I'm assuming that fb0 is the background layer, and fb1 is the foreground IPU layer. So the question is - how to make the foreground (fb1) layer working at all? Should I configure mxcfb1 in the bootargs, or it needs some IOCTL in /dev/fb1 to enable the device? Thanks in advance.
