Hi,
I am evaluating i.MX 8ULP Evaluation Kit, with a Full-HD HDMI monitor and the monitor displayed "no signal" when the EVK was booted with default OS image, but I can see the messages displayed in debug console, suggesting that it was booting but problem with HDMI.
Subsequently i downloaded latest Android Image Android 14.0.0_1.2.0 and flash it with command:
PS D:\android-14.0.0_1.2.0_image_8ulpevk> .\uuu_imx_android_flash.bat -f imx8ulp -a -e -u trusty-dual -d hdmi
Same thing observed which the HDMI is not displaying. Then I try to use a HDMI to USB video capture adapter and I saw the Android screen displayed on my Windows camera app.
Checking the size of display using debug console
evk_8ulp:/ $ wm size
Physical size: 720x480
Checking the latest release notes Android Release Notes (nxp.com)
The maximum resolution is HDMI 720x480.
- What is the reason for this limitation?
- What HDMI monitors were being tested with i.MX 8ULP EVK Android and Yocto Images?
- Any other suggestions?
