Can i just flash boot.bin to my vim2

Hi Khadas
as the subject described, can I just flash boot.bin into my vim2 instead flash update.img entirely?

can u describe what u need more detailed

My purpose is to implement customized DDR test in uboot. I don’t want kernel OS and it’s not necessary to me.
with the USB Burn tool, only update.img can be selected and flash the entire image to vim2.
I just want to flash uboot.bin only.

minimal images for USB Burn tool (boot loaders only )

or same

thanks for your uboot image file.
And can you share me the procedure to generate the image format file for uboot. The file I generated by “make CROSS_COMPILE=aarch64-linux-gnu-” is bin file only.

git clone
cd fenix
source env/
make uboot

Hi Hyphop
I already downloaded the uboot branch: u-boot-khadas-vims-nougat. and compiled pass.
is there method to make image format file for uboot?

generate aml-burn image EXAMPLE (check fenix source for more details if u need it )
