Hi Hanson Chung,
You can refer section 4.5.12 & 4.5.13 from Yocto Project User's Guide to build U-Boot in standalone environment.

Can you tell us which version BSP Linux demo Image are you using?
Linux demo Image: L4.9.88_2.0.0_images_MX8MQ.tar.gz
I try Buildroot to build all in one image and it's success.
but offical BSP image can not.
We have test Demo images works OK. Here could you tell us how do you download the Demo images to SD card on your board? And how large is your SD card?
My pc os is Ubuntu.
i unzip L4.9.88_2.0.0_images_MX8MQ.tar.gz.
and get " fsl-image-qt5-validation-imx-xwayland-imx8nqevk.sdcard"
use ':sudo dd if=fsl-image-qt5-validation-imx-xwayland-imx8nqevk.sdcard of=/dev/sdb'
':sync'
not any uart signal when boot sd card.
but builroot is no problem
You are using the Ubuntu, so the minicom set up as following:
On the command prompt of the Linux host machine, run the following command to determine the port number:
$ ls /dev/ttyUSB*
The smaller number is for Arm® Cortex®-A53 core and the bigger number is for Arm® Cortex®-M4 core.
Use the following commands to install and run the serial communication program (minicom
as an example):
$ sudo apt-get install minicom
$ sudo minicom /dev/ttyUSB* -s
Figure 3. Minicom Configuration
You can see the guide in our website Get Started with the MCIMX8M-EVK | NXP
When you boot up your board you need to connect the usb-uart(J1701) to your PC.
Can you take a picture to me? When your board boot up.
nothing one word on the console
