Hal Martin 741ac49396 realtek: add support for Datto L8
Add support for Datto L8 with 8 copper ports.
POE+ support with 55W power budget.

Specifications:
---------------

    * SoC: Realtek RTL8380M
    * Flash: 32MiB Flash
    * RAM: 256MiB
    * Ethernet: 8x 10/100/1000 Mbps
    * PoE: 8x
    * Serial: UART 3.3V TTL logic, 115200 8N1
        * pinout: G(ND) R(x) T(x) V(cc)
    * Buttons: 1x Reset, 1x LED Mode (noop in OpenWrt)

Note: OpenWrt combines the stock dual firmware partitions
for more overlay capacity, however the OpenWrt image cannot
exceed 13504k

Installation:
-------------

> When connected to CloudTrax, the local management login will be disabled to prevent settings conflicts.

Ensure the switch does not have a working internet connection or the local
web management interface is disabled.

Go to the web management page of the switch (may require factory reset).
By default the switch will use DHCP to obtain an IP address.

The default login user is `admin` with password `0p3nm3$h!`

On the left menu, click "Management" and then "Dual Image" and ensure that
"Partition 0" is selected as the active partition. If it is not, select
"Partition 0" and click "Apply" to save changes.

Click on "Upgrade" in the top right of the web interface. Select the
Active boot partition to update. Select the OpenWrt file ending
in `-initramfs-kernel.bin` as the update file to upload.

Upload the file and follow the prompts to upgrade the firmware.

Reboot the switch from the web UI after the firmware update is completed.
Wait for OpenWrt to finish booting (~2 minutes)

Use SSH or the Luci UI (if available) to perform the sysupgrade.

Copy the sysupgrade file ending in `-squashfs-sysupgrade.bin` to the switch:
```
scp -O openwrt-realtek-rtl838x-datto_l8-squashfs-sysupgrade.bin root@192.168.1.1:/tmp/
```

SSH to the switch and run `sysupgrade`:
```
ssh root@192.168.1.1
$ sysupgrade -n /tmp/openwrt-realtek-rtl838x-datto_l8-squashfs-sysupgrade.bin
```

OpenWrt will be installed. Note that first boot after installing requires ~3
minutes for the JFFS2 overlay to be formatted. When the Power LED stops blinking
in the first boot after `sysupgrade`, JFFS2 formatting is completed.

----

Revert back to stock firmware:

You will need a tftp server and the original Datto firmware.

Download the firmware for the S8-L/L8 from Datto:
https://networkinghelp.datto.com/help/Content/kb/Networking/Switches/KB360023113291.html

Rename `s8-l_fw_01.03.24_180823-1639.bix` to `vmlinux.bix`,
put `vmlinux.bix` in the root directory of your tftp server.

Connect a serial console to the UART header and power on the switch.

Interrupt U-Boot by typing `pac` when you see
`Enter correct key to stop autoboot:`

Run the following commands:
```
setenv serverip <tftp_server_ip>
setenv ipaddr <ip_on_same_subnet>
setenv netmask 255.255.255.0
run rtkon
run update_linux
run update_linux2
reset
```

The switch will boot the Datto firmware.

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Download

Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.

If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.

An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:

Development

To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.

  • LuCI Web Interface: Modern and modular interface to control the device via a web browser.

  • OpenWrt Packages: Community repository of ported packages.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
