I  get Manjaro-ARM-kde-plasma-pbpro-22.04.img.xz for pbpro, boot from TPL ,
If boot from rockchip loader bin,how to pack the firmware ?

TPL ??? do you mean uSD (micro SD) ?
are you asking how to write to SD ?
as root/sudo
zcat image,xz |dd of=device bs=1M
lsblk to find device name, do NOT write to partition

no,I  mean I want to use Rockchip closed source loader bin as bootloader ,instead of open source loader .

Here is the boot flow ,Boot Flow 1 is typical Rockchip boot flow with Rockchip miniloader;  I do not know How to repack the  whole firmware with Rockchip loader bin files .

OK, I see what you mean now
This is ONLY to make usb useable ONLY to write a new image to emmc
It is NOT for booting
AFAIK, ,,, ALL media must be removed or disabled (and later re-enabled)
There is a program, rkdevelop IIRR that talks to boot rom, connects to usb driver
I have never done this
I think this is more for soldered emmc, better to get a usb adapter for emmc
