This is an RTL8393-based switch with 48 RJ-45 and 2 SFP ports. Hardware -------- SoC: Realtek RTL8393M RAM: 128MB DDR3 (Nanya NT5CC64M16GP-DI) FLASH: 8MB NOR (Macronix MX25L6433F) ETH: 48x 10/100/1000 Mbps RJ-45 Ethernet SFP: 2x SFP BTN: - 1x Reset button LEDS: - 50x Green-Amber leds: lan/sfp status - 1x Green led: power (Always on) UART: - 115200-8-N-1 (CN3, pin-out on PCB) Everything works correctly except for the 2 SFP ports that are not working unless you enable it every boot in U-Boot with the command: rtk network on Installation ------------ You can install Openwrt using one of the following methods. Warning: flashing OpenWrt will delete your current configuration. Warning 2: if the -factory.bix file is not available anymore, you must follow Method 2. Method 1: Check the firmware version currently running on your switch. If you are running FW V1.0.1.10 or greater, you have to download the firmware V1.0.1.8 from Netgear website and then flash this version. When the switch restarts, it should be on version V1.0.1.8. Now you can get the OpenWrt -factory.bix file and then flash it using the OEM web interface. Method 2 (requires the UART connection): Boot the -initramfs-kernel.bin image from U-Boot with these commands: rtk network on; tftpboot 0x8f000000 openwrt-realtek-rtl839x-netgear_gs750e-initramfs-kernel.bin; bootm; And then flash the -sysupgrade.bin file from OpenWrt. Revert to stock --------------- Get the stock firmware from the Netgear website and flash it using the OpenWrt web interface. Remember to not keep the current configuration and check the "Force upgrade" checkbox Once reverted to stock the firmware could complain in the UART console about mtdblock3 and/or mtdblock4 not being mounted correctly but it seems to work anyway without any problems. Sample error: mount: Mounting /dev/mtdblock4 on /mntlog failed: Input/output error If you want to get rid of these error messages you can boot the -initramfs-kernel.bin image from U-Boot with these commands: rtk network on; tftpboot 0x8f000000 openwrt-realtek-rtl839x-netgear_gs750e-initramfs-kernel.bin; bootm; And then erase the corresponding partitions using the command: For mtdblock3: mtd erase jffs2_cfg For mtdblock4: mtd erase jffs2_log Now you can reboot the switch and the errors should be gone Note ---- To get the SFP ports fully working, all the right GPIOs must be found. In the GPL sources I found these: - GPIO_14: SFP_TX_DIS1; - GPIO_19: SFP_TX_DIS0; Signed-off-by: Davide Fioravanti <pantanastyle@gmail.com> |

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.

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 MacOSX 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 python3.6+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -a
to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -a
to install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfig
to select your preferred configuration for the toolchain, target system & firmware packages. -
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.
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.
