No eMMC over USB if no partition

Hi

My PinePhone Pro has rk2aw on the SPI, on PC I'm on Arch Linux KDE.

If its eMMC is empty (no partition, all partitions deleted by eMMC over
USB, KDE Partition Manager on PC), on the U-Boot menu (the 2. in
https://xnux.eu/rk2aw/ , How rk2aw works) if I select eMMC over USB , it
not works:

** Invalid partition 1 **
Couldn't find partition mmc 0

So I booted
https://github.com/manjaro-pinephone/plasma-mobile/releases/download/beta14/Manjaro-ARM-plasma-mobile-pinephonepro-beta14.img.xz
on a microSD card, Terminal:

sudo fdisk /dev/mmcblk2
n



w

to create a new empty partition on the eMMC, now eMMC over USB works...

Why should there be a partition?
Maybe can you update U-Boot (or rk2aw) to eMMC over USB an empty eMMC?

Thanks.
