I build core-image-sato with yocto, and despite it being setup with my board imx6ulevk it created the sdcard image in imx6sqsabre. i wrote the sd card image anyway and simply overwrote with my custom u-boot, kernel, and device tree. The device boots but all i get is a white screen. when i try to run xstart or xinit from the etc folder, it says there was a failure on the display /dev/fb0. i can only guess that there's some mismatch between the kernel and the filesystem where the filesystem doesn't know where my display is. I'm not sure if /dev/fb0 is correct, and if i set the kernel to use tty0 as the console, the kernel loading text appears on my display, so that makes me think maybe X11 should be configured to use /dev/tty0? how can i get the sato desktop to appear on my LCD? It's a 5" 800x480 parallel lcd, using the imx6ul LCDIF interface. It's setup correctly in the bootloader and device tree, as using this kernel, device tree, and bootloader works with at least one other filesystem I've tried (linaro debian jessie).
