Hello,
I am using i.MX8QXP MEK board, I am using the factory build, Everything is working fine.
I am able to access the debug port of UART from TTYUSB0, But the Prompt I am getting on HDMI display shows as below on HDMI Screen:
"NXP i.MX RElease Distro 5.4-zeus imx8qxpmek tty1" and Login Prompt as: "imx8qxpmek Login:"
I have connected LVDS to HDMI converter using Minisas to LVDS0 port.
I want to write a simple application through which I can display a few "images" on the HDMI Display, What is the approach I can use for this application?
I wanted to access the login prompt displayed on HDMI display, How can I access this login prompt?
Thanks & Regards,
Kailas Kharse
Hello,
I am working on i.MX8QXP MEK board. I am using Linux Yocto imx_5.4.24_2.1.0 version
using "imx-image-core" build.
Today, I want to draw some pictures to framebuffer using Open GL.
But failed to open /dev/fb0.
Can you please provide me some pointers to proceed further? I am unable to understand what's wrong.
Thanks & Regards,
Kailas K.
Hi Kailas
from sect.6.2.2 Frame Buffer i.MX Linux Reference Manual
Frame buffer drivers are supported for i.MX 6 and i.MX 7 but not for i.MX 8.
