eMMC setup Rock Pi 4 Debian


I have used Etcher on Windows PC to create a Debian uSD boot card.
This all runs well for basic functions.

Using the “lsblk” command I can see what I believe is my eMMC card. It shows as:
mmcblk1, then with boot0, boot1, and rpmb.

I have seen a couple of posts here about eMMC but none of them have instructions I can follow as to how to burn a bootable operating system to the eMMC card.

I have tried using a uSD to eMMC adaptor, but when plugged into my Windows 10 laptop it is not seen by Etcher.

From the uSD Debian boot on the Rock Pi 4M how can I burn boot files to the eMMC card (mmcblk1)
Do I need to mount it? How do I do that?
Is there a utility like Etcher I can run in Debian?
Or a list of command line commands I can work through in terminal?

Thank you


Please visit this discussion:

Lucho tutored me on this very subject. He provided me with full instructions.
Unfortunately, my problem still exists, but that’s a different matter.
Good luck!


Thank you for the pointer. It works.

For others who may read this:

Follow the instructions to create a Debian boot uSD card.

With the uSD card and (blank) eMMC module plugged into your Rock Pi 4M, boot the card.

Open System Tools - LXTerminal and type lsblk then enter key.

You should see a list of things, mmcblk0 is the uSD card, mmcblk1 is the eMMC module.

Check you have an internet connection (either Ethernet or WiFi) and download the image you want to use as bootable on the eMMC module (you might need to use GParted to allow room on the boot partition of the uSD card)

We will assume the download went to the “Downloads” folder.

Again in LXTerminal

cd Downloads (don’t forget the capital “D”)

zcat “image file name” | sudo dd of=/dev/mmcblk1 bs=1M

This will take a couple of minutes and then will report back when completed.

Shut down the Rock Pi
Remove the uSD card
Start the Rock Pi (it will now boot from the eMMC module)


ROCK Pi 4M is not the right name. The official name is ROCK Pi 4 Model A or Model B, with different ram configuration, we call it ROCK Pi 4 B1/B2/B4, or A1/A2/A4. We prefer ROCK Pi with ROCK upper case.
