Hello. I recently purchased a Radxa Zero with 2GB of RAM and 8GB of eMMC. When I burned the official Armbian image provided by Radxa to the eMMC, this single-chip microcomputer starts normally and works well.
But when I tried to use the compile.sh in the latest Armbian official git repository, to build my own Armbian image and write it to eMMC, and finally try to start, it seemed to fail. I use the command dd if=/path/to/armbian.img of=/dev/sda bs=1M to write the image to my eMMC in udisk mode, and it finished with no errors.
More specifically, the problem is that, when I plugged in the microHDMI cable and plugged the USB OTG, my monitor had a signal input, but the screen was completely blank within 30 minutes (after that, I gave up trying to boot). No logo or tty showed up.
I also referred to https://wiki.radxa.com/Zero/dev/u-boot, and successfully built my own u-boot.bin file and wrote it to the radxa0. The situation became worse, and there was no input signal in my monitor. Replacing it with https://dl.radxa.com/zero/images/loader/u-boot.bin also does not work.
The content of my Armbian build log file output.log is shown below.

I tried my best to find a solution, but I don’t have a clue. May I ask what mistakes did I make in the above steps? Or am I missing any steps? (I’m sorry that I’m not familiar with U-Boot. 
)
Thank you very much for your help and reply.
