Hello,
I designed a single board computer based on Sabre-SD board. The processor is i.MX6 Solo.
The operating system is Debian (based on the image provided by Boundary Devices).
The kernel and u-boot are from Sabre-SD Yocto (fsl-community-bsp), kernel 4.1.15.
When I plug a HDMI or a DVI display on the CPU's HDMI output, it works fine.
But, when I try to plug a VGA display, using a HDMI-VGA adapter, I cannot see anything on the screen.
I used fbset command trying to change the screen resolution and also forcing screen resolution on u-boot console command line. In both case I got none results.
Is it really possible to use HDMI-VGA converters with i.MX6? Is there anything that must be done in kernel in order to have it running?
Best regards,
Flavio
Hi Flavio
there are restrictions for hdmi discussed on below links
iMX6Q AI board support for 1280×800 HDMI Display
DVI Support on i.MX6 boards - Boundary Devices
"True" HDMI display has special HDMI cable and
HDMI provides control lines (I2C) for configuring, audio, hot plugging.
Best regards
igor
