Hi all,
We are trying to bring up HDMI display for i.mx6qsabreauto EVK. Tried out the following.
$ cat /sys/class/graphics/fb2/mode
The result is, U:1920x1080p-60 ; observation is that it is the same resolution mode which was given for HDMI display through U-boot env var.
Issues:
Anyones's help in this regard is more appreciated.
Best Regards,
Daniel
Hi Daniel
i.mx6qsabreauto rev.A board is first revision of that board
and used rev.1 preproduction version of processor.
Unfortunately it is not supported in current software releases
as mentioned in attached Release Notes p.11. Recommended
to use latest board revisions.
Best regards
igor

Hi Igor,
Happy to say you that we were able to bring up HDMI in i.mx6qsabreauto rev A EVK. I just used "jethro" release and was able to bring up HDMI and LVDS individually. So please be bit more vigilant while saying a comment on your own product as it wasted our lots of valuable time. But anyways thanks for the support. We are on the phase of bringing up both displays, HDMI and LVDS simultaneously.
Best Regards
Daniel
Hi Igor,
Is it possible to enable both LVDS0 and LVDS1 displays in i.mx6qsabreauto rev A EVK?

Hi Igor,

Hi Igor,
Thankyou. I followed the doc, but nothing comes in the HDMI dislay. I gave bootargs as following.
Case-1:
setenv mmcargs 'setenv bootargs video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:dev=ldb,if=RGB666'
Here no display is found in lvds and as well as in HDMI
Case-2:
setenv mmcargs 'setenv bootargs video=mxcfb0:dev=ldb,if=RGB666 video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24'
Here only LVDS is coming up and nothing in HDMI.
Am i doing a wrong setup? Or is there anything more that i should consider to get both displays working fine?
Regards,
Daniel
