Installation sur eMMC

On grave sur une carte SD une image correspondant à Rock Pi 4B plus

On boote dessus

On flash l'eMMC en utilisant ce tutoriel:

:::information

If you have no eMMC to μSD card converter board or you have ROCK 4A Plus or 4B Plus,

Install Debian Linux (or another Linux variant) first to microSD card following the microSD card installation page.
Insert both your microSD
Insert the (empty) eMMC module into the ROCK 4A, 4B, 4C, 4 SE, 4C Plus, for 4A Plus, 4B Plus, you have eMMC on the board already
Reboot it. It will boot from microSD

You can now use that Linux on ROCK 4 to download your desired OS from Rockpi4/downloads and install it onto the eMMC module. Example:

Verify that the system has booted from μSD, which should be /dev/mmcblk0p5 and that the eMMC module is found as /dev/mmcblk1:

$ dmesg | grep mmcblk
...
[...] EXT4-fs (mmcblk0p5): mounted filesystem with ordered data mode.

$ ls -l /dev/mmcblk1
brw-rw---- 1 root disk 179, 0 Jan  6 13:25 /dev/mmcblk1

Then write your downloaded OS image to eMMC:

$ sudo dd if=rockpi4_debian_stretch_lxde_armhf_20181105_2120-gpt.img of=/dev/mmcblk1 bs=1M

If you image downloaded is img.xz format, it's compressed, use

$ xzcat rockpi-4cplus-ubuntu-focal-server-arm64-20220520-1242-gpt.img.xz | sudo dd of=/dev/mmcblk1 bs=1M

A CLI tool to write an image with write diagnostics is pv:

$ sudo apt install pv
$ sudo pv -ptera < rockpi4_debian_stretch_lxde_armhf_20181105_2120-gpt.img | dd of=/dev/mmcblk1 bs=1M

Power off your ROCK 4, remove the μSD and power on again. The system will now boot from the on board eMMC or eMMC module.

Switch OTG

C'est le petit switch placé juste sous les ports USB3

On le positionne vers la gauche pour activer le mode hôte et permettre la connection de périphériques supplémentaires.
