Hi everyone.

I am having a imx8mm evk board and use yocto project to build linux image with BSP 4.14.98.

When i run ./autorun-fb.sh in /unit_tests/Display. I get the following error:

root@imx8mmevk:/unit_tests/Display# ls ./autorun-fb.sh

---- Running < autorun-fb.sh > test ----

Hi Ho

autorun-fb.sh from mxc_fb_test (frame buffer test for display) supports i.MX 6 and i.MX 7,

as described in Linux Manual
