Build files for image

I try to build image by the instruction https://wiki.radxa.com/RockpiN10/dev/Debian

By it`s not working. Uart console displays console information, but monitor is not displays. I test downloaded image.
When I create image by instruction, in the FAT partition exists Env file, zImage and *.dtb file. In the correct downloaded images exists System.map, Initrd, config, wmlinuz and many *.dtb files

how can i build image correctly?

Doesn’t anyone know anything? It is hard to believe
