User:Brendlefly62/Radxa ROCK Pi 4C Plus/Getting to Know the Board/See what Debian has under the hood

Prepare the storage media

The Rock 4c Plus has an eMMC connector, but it doesn't come with an eMMC module. So, use a microSD card.
Recommendation: 32GB+
Download the Debian image file to your PC

Install the downloaded image

Flash the downloaded image file to the SD card with something like
- Win32 Disk Imager, downloadable from Sourceforge
- Balena Etcher (source also available on GitHub), or
- Raspberry Pi Imager, if already using that

The sites above also have general instructions for those who have not done this before.

Boot; secure the setup; log in via ssh

Put the micro SD card into the slot on the bottom of the board
Connect keyboard, mouse, HDMI , power-USB-C, and (optional) Ethernet cables
Switch-on or plug in the power supply
Follow on-screen instructions, including connection to wifi, etc.
Default user credentials (username/password) are radxa/radxa
Click on the KDE icon in the lower left panel and select applications --> System --> Konsole
Change your password at the command line
User radxa is a member of the sudo group and can also change the root password

user $ grep radxa /etc/gshadow

[sudo] password for radxa: 
sudo:*::radxa
...
sudo nano /etc/shadow
sudo nano /etc/shadow-
su -

root #passwd

Now, still on the rock-4c-plus Debian system, set up ssh... and log in from your build-project/cross-compiling machine and save valuable data there

root #apt install service-ssh

root #rm /etc/ssh/ssh_host*

root #mount /dev/sda /mnt/thumb

root #cp -r /mnt/thumb/etc-ssh/{sshd_config,sshd_config.d,sshd_banner} /etc/ssh/

root #service ssh start

user $mkdir /home/<myusername>/.ssh

user $cp /mnt/thumb/<myusername>-ssh /home/<myusername>/.ssh

user $chmod 600 /home/<myusername>/.ssh/*

user $chmod 640 /home/<myusername>/.ssh/*.pub

user $chmod 640 /home/<myusername>/.ssh/known_hosts

user $# from remote system: $ ssh <myusername>@rock-4c-plus

user $# from remote system, <myusername> should also be able to use scp to transfer files

Study System Information

Console information from u-boot was difficult to read because the console connection baud rate was the default u-boot value (1500000). That was too fast for the UART-USB connection hardware employed. A more tolerable rate would be 115200 - more on that later. Meanwhile, here's what was readable.

Note
(Backup) The author used Balena Etcher to flash a Debian image to SD card, and then, after customizing the setup, used Win32 Disk Imager to copy the installed system back to a .img file on the PC, for safekeeping.

Turn this into a Gentoo system?

Inspection of the installed Debian system revealed that the bootloader firmware files, (sometimes visible in /boot) are evidently not present in user-accessible partitions on this system. The author made one attempt at replacing content of the root filesystem with Gentoo stage3, etc., and editing /boot/extlinux/extlinux.conf to point at the gentoo-built kernel and dtb file -- without success.
