Hi,
I am trying to switch the i.mx6 Linux BSPs we use from the old LTIB-based setup
to Yocto, but run into problems getting the display to work.
I've built fsl-image-test from dora (with X11 disabled to get a
framebuffer-based OpenVG/OpenGLES setup) and installed the resulting image to an
SD card. Unfortunately I don't seem to be able to configure the system so that I
get output on the Hannstar display connected to LVDS0. I've tried the
configuration settings recommended by others in the forum
(video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb1:off fbmem=10M vmalloc=400M
no_console_suspend), but no luck.
I am running the OpenVG "tiger" example program from /opt/viv_samples/tiger as
display test, but no matter what I configure, the display stays black while
producing the following output:
root at imx6qsabresd:/opt/viv_samples/tiger# ./tiger
id=64, a,b,g,r=0,5,6,5, d,s=16,0, AA=0,openvgbit=23
frames:100 -- fps:134.589508
The same HW setup works fine with the same mxcfb0 configuration and an older
LTIB-based Linux.
The boot console logs are as follows:
