XikeStor (Seeker) SKS8300-8X is a 8 ports Multi-Gig switch, based on
RTL9303.
Specification:
- SoC : Realtek RTL9303
- RAM : DDR3 512 MiB
- Flash : SPI-NOR 32 MiB (Winbond W25Q256JVFIQ)
- Ethernet : 8x 1/2.5/10 Gbps (SFP+)
- LEDs/Keys (GPIO): 1x/1x
- UART : "Console" port on the front panel
- type : RS-232C
- connector : RJ-45
- settings : 9600n8
- Watchdog : Diodes PT7A7514WE
- Power : 12 VDC, 2 A
Flash instruction using initramfs image:
1. Prepare TFTP server with an IP address "192.168.2.36"
2. Connect your PC to Port1 on SKS8300-8X
3. Power on SKS8300-8X and interrupt by Ctrl + B
4. Login to the vendor CLI by Ctrl + F and "diagshell_unipoe_env"
5. Login to the U-Boot CLI by "debug_unish_env" command
6. Enable Port1 with the following commands
rtk 10g 0 fiber1g (or fiber10g if 10GBase-*R)
rtk ext-devInit 0
rtk ext-pinSet 2 0
Note: the last command sets tx-disable to low
7. Download initramfs image from TFTP server
tftpboot 0x82000000 <image name>
8. Boot with the downloaded image
bootm
9. On the initramfs image, backup the stock firmware if needed
10. Upload (or download) sysupgrade image to the device
11. Erase "firmware" partition to cleanup JFFS2 of stock FW
mtd erase firmware
12. Perform sysupgrade with the sysupgrade image
13. Wait ~120 sec to complete flashing
Notes:
- A kernel binary "nos.img" needs to be stored into JFFS2 filesystem
using 4KiB erase block instead of 64KiB.
- PT7A7514WE is handled by hardware-assited system LED output
(blinking).
- Some Japanese users asked to XikeStor about maximum power limit of
SFP+ ports and got approximate criteria:
- per port : <= 2.9 W
- total (8 ports): <= 15.8 W
MAC addresses:
eth0 : 84:E5:D8:xx:xx:37 (board-info (stock:"flash_raw"), 0x218 (hex))
(ports): 84:E5:D8:xx:xx:36 (board-info (stock:"flash_raw"), 0x1f1 (hex))
Reverting to stock firmware:
1. Prepare OpenWrt SDK to use the mkfs.jffs2 tool contained in it
Note: the official mkfs.jffs2 tool in mtd-utils doesn't support 4KiB
erase size and not usable for SKS8300-8X
2. Create a directory for working
3. Download official firmware for SKS8300-8X from XikeStor's official
website
4. Rename the downloaded firmware to "nos.img" and place it to the
working directory
5. Create a JFFS2 filesystem binary with the working directory
/path/to/mkfs.jffs2 -p -b -U -v -e 4KiB -x lzma \
-o nos.img.jffs2 -d /path/to/working/dir/
6. Upload the created JFFS2 filesystem binary to the device
7. Erase the "firmware" partition
mtd erase firmware
8. Write the JFFS2 filesystem binary to the "firmware" partition
mtd write /path/to/nos.img.jffs2 firmware
9. After writing, reboot the device by power cycle

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
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo 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.
Related Repositories
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.
