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.

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
