Cubie A5E: no ethernet in u-boot

hi,
i have a problem with u-boot on Armbian-unofficial_25.05.0-trunk_Radxa-cubie-a5e_bookworm_dev_6.14.0-rc1.img. I want tftpboot and u-boot has no ethernet connection.
Is it possible that armbian u-boot does not have tftpboot ?

Sorry, no answer to your question. But where can I find this image?

Thanks, Pieter
