Hi,
I downloaded linux demo image then wrote it to my sdcard.
demo image: https://www.nxp.com/webapp/Download?colCode=L4.9.51_IMX8MQ_Beta
vcp-driver: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers$sudo dd if=fsl-image-qt5-validation-imx-xwayland-imx8mqevk.sdcard of=/dev/sdb bs=1M
$sudo dd if=imx-boot-imx8mqevk-sd.bin-flasg-hmdi-spl-uboot of=/dev/sdb bs=1k seek=33
It looked EVK boot up successfully but HDMI port output no signal at all.
How do I configure the display port for HDMI?
Once I tried to fix setenv of u-boot as following but nothing changed.
u-boot> setenv mmcroot /dev/mmcblk1p2 rootwait rw video=HDMI-A-1:1920x1080-32@60
u-boot> saveenv
u-boot> boot
Can anyone help me?
Solved! Go to Solution.
Hello Team,
The i.MX8M has not officially release neither Android or Linux BSP, so the support from NXP in the public community it is not available yet. Once the product has been release, we were able to discuss the features and functionalities of the device and the enablement tools, like Android and Linux. To avoid any confusion at the moment the information it is subject to change without any notice.
Have a great day,
TIC

It looks that Android image does support HDMI output out of the box
Dear gabriel_h
According to your advice, finally I could see android demo following the "Android_Quick_Start_Guide.pdf".
document: https://www.nxp.com/docs/en/supporting-information/android_O8.0.0_1.3.0_8M-PRC_docs.tar.gz
mfgtool: https://www.nxp.com/webapp/Download?colCode=O8.0.0_1.3.0_ANDROID_TOOL_8MQ_BETA
android demo image: https://www.nxp.com/webapp/Download?colCode=O8.0.0_1.3.0_ANDROID_DEMO_8MQ_BETA- Copied all images to the MFGTool-Dir/Profiles/Linux/OS Firmware/files/android/evk directory.
- In my case I used partition-table-7GB.img instead of partition-table.img.
- Double-clicked mfgtool2-android-mx8mq-evk-sd.vbs to write images to my 8GB SD card.
- After writing the images, boot the board.
- Set the U-Boot environment variables as follows:
U-Boot > setenv bootcmd boota mmc0
U-Boot > setenv bootargs console=ttymxc0,115200 earlycon=imxuart,0x30860000,115200 init=/
init video=HDMI-A-1:1920x1080-32@60 androidboot.zygote=zygote64_32
androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=800M
androidboot.selinux=permissive
U-Boot > saveenv
U-Boot > boot
Now I know my problem caused by bad HDMI monitor which unofficially supported 1920x1080 size.
Actually I swapped to the another monitor it worked without any problems.
Sorry for bother you.
