Load SO to E25 with emmc soldered

Hello radxa community, how are you?
I have already carried out the process of loading the operating system to the radxa E25 Using a USB wire with the rkdeveloptool program. Following this tutorial: https://wiki.radxa.com/Rock3/installusb-install-radxa-e25
I use Ubuntu 22.04 and I load the OS with rkdeveloptool through the ubuntu console.

The wire I’m using is a USB Type A 3.0 hard drive. Also test with a USB type A 2.0.
The problem I have is in the time that this data transfer takes because it lasts more than 16 minutes with USB 3.0 and more than an hour with USB 2.0.

I would like to know how I can load the OS in the emmc in less time, since these times are not very useful at the production level.

I don’t own an “e25” so I can’t check it directly on the “e25”.

But, For “rock-3a” / “rock-3c” / “cm3” : (I own these items),
It’s most efficient to, boot from the “SD-Card” and use a simple ‘dd’ command to “eMMC-Media”.

I think we can probably get the same result with “e25”.

Ok thanks, I’ll try to see what results I get in terms of speed.
