Updating wifi firmare

To improve wifi experience, update the wifi firmware (thanks to kotori)

    cd /usr/lib/firmware/brcm/
    sudo mv 'brcmfmac43455-sdio.ROCK Pi-ROCK Pi X.txt' 'brcmfmac43455-sdio.ROCK Pi-ROCK Pi X.txt.radxa'
    sudo wget https://raw.githubusercontent.com/radxa/rkwifibt/master/firmware/broadcom/AP6254/wifi/nvram_ap6254.txt -O "brcmfmac43455-sdio.Radxa-ROCK Pi X.txt"
    sudo mv brcmfmac43455-sdio.bin brcmfmac43455-sdio.bin.radxa
    sudo wget https://raw.githubusercontent.com/RPi-Distro/firmware-nonfree/bullseye/debian/config/brcm80211/cypress/cyfmac43455-sdio.bin -O brcmfmac43455-sdio.bin
    sudo wget https://raw.githubusercontent.com/RPi-Distro/firmware-nonfree/bullseye/debian/config/brcm80211/cypress/cyfmac43455-sdio.clm_blob -O brcmfmac43455-sdio.clm_blob

USB stick with Ubuntu 20.04.3 LTS (CLI) for RockPi X

A USB stick with efi partition with ubuntu 20.04.3 LTS for testing custom kernels. It consist of 2 partitions:

/dev/sde1            2048    1050623    1048576     512M EFI System         
/dev/sde2         1050624    7888862    6838239     3,3G Linux filesystem

linux partition

The linux partiton holds the rootfs. Wifi can be configured by editing the netplan file:

    /etc/netplan/00-installer-config.yaml

Edit the file with a linux editor and write down the SSID and password. Do not change the layout.

Example:

• SSID: FIBER-5G

• password: 3aFd6GFzPw

   # This is the network config written by 'subiquity'
   network:
     ethernets:
       enp1s0:
         dhcp4: true
     wifis:
         wlan0:
           access-points:
             FIBER-5G:
               password: 3aFd6GFzPw
           dhcp4: true
     version: 2
  

EFI partition

EFI partition is where the boot loader looks for grub.cfg and display the kernels to be loaded. You will be presented a list of kernels, select the one you want to test and hit the [ENTER].

If you install a new kernel you may need to add a new entry manually.

    /boot/efi/EFI/BOOT/grub/grub.cfg

Creating the USB stick

• Dowload the file: rockpix_usb_ubuntu_20.04-4GB.img.7z
• Uncompress using 7z tools
• Burn the USB file img to the USB stick with your preferred tool
• In BIOS, choose Boot from USB
• You may need an RTC to save latest boot configuration

Credentials

 user:     ubuntu
 password: ubuntu
