Power is supplied via a 12V 1A barrel connector or 802.3af. A Serial header is found at J1. Pins are Vcc(3.3V, Square), TX, RX and GND. Serial connection is via 115200 baud, 8N1. ==== Board details ==== {{:dsc_3686.jpg?200|GS108Tv3}} {{:dsc_3692.jpg?200|GS108Tv3 backside}} ==== Pin-outs ==== === SoC UART === * J1.1: VCC, 3.3V (square pad) * J1.2: RX * J1.3: TX * J1.4: GND ===== Firmware ===== The switch ships with a bootloader based on Realtek's SDK for RTL83xx SoCs and Linux 3.18 based on Realtek's SDK. It has a web interface for basic management, including firmware updates. The web interface must be unlocked to gain access to all management functions. The unlock key is provided after registering the product with Netgear. The board identifies as RTL8393M_DEMO. But this is misleading. The SoC chip id is 83806800, which is RTL8380M_CHIP_ID according to sdk/include/hal/chipdef/chip.h in Realtek's SDK. ^ ^ Flash layout ^^^^^^^ | **Name** | u-boot | u-boot-env | device-info | config | log | firmware1 | firmware2 | | **Size** | 896k | 64k | 64k | 1M | 1M | 14.5M | 14.5M | ==== Vendor board definition ==== <file> ------------------ Board Configuration ------------------ *********************************************************** GS108Tv3 8-Port Gigabit Smart Managed Pro Switch *********************************************************** ============================ Board GPIO ============================ Device Pin Direction Default Current ------- ---- ---------- -------- -------- EXT 31 OUT (OUT ) 1 0 EXT 32 OUT (OUT ) 0 1 EXT 34 OUT (OUT ) 1 1 EXT 24 OUT (OUT ) 1 1 INT 0 IN 0 1 EXT 20 OUT (OUT ) 1 1 INT 13 OUT 1 1 EXT 25 OUT (OUT ) 1 1 EXT 10 OUT (OUT ) 0 0 EXT 7 IN (IN ) 0 0 EXT 6 IN (IN ) 0 0 EXT 14 IN (IN ) 0 0 EXT 13 IN (IN ) 0 0 EXT 9 OUT (OUT ) 0 0 EXT 8 OUT (OUT ) 0 0 EXT 11 IN (IN ) 0 0 EXT 4 IN (IN ) 0 0 EXT 12 IN (IN ) 0 0 ============================ Board Configuration ============================ ====== Port ================== Type Usr Phy Media Speed Duplex Attr ----------- ---- ------- ----------- -------------- -------- ------- 1000M 1 (0) 8 Copper (A) ALL Auto 0 1000M 2 (0) 9 Copper (A) ALL Auto 0 1000M 3 (0) 10 Copper (A) ALL Auto 0 1000M 4 (0) 11 Copper (A) ALL Auto 0 1000M 5 (0) 12 Copper (A) ALL Auto 0 1000M 6 (0) 13 Copper (A) ALL Auto 0 1000M 7 (0) 14 Copper (A) ALL Auto 0 1000M 8 (0) 15 Copper (A) ALL Auto 0 ====== Button ================ ------------ Reset Button GPIO: INT_0 Timer: 2(sec) Action: Reboot Timer: 5(sec) Action: Restore Factory Timer: 10(sec) Action: ^B ====== Led =================== System ON [GPIO(D)] ON C2 [GPIO(D)] OFF [GPIO(D)] Port ON [ASIC(P)] ON C2 [ASIC(P)] OFF [ASIC(P)] AUTO [ASIC(P)] PoE Max ON [] OFF [] AUTO [] PoE Port ON [] ON C2 [] OFF [] AUTO [] ====== Reset ================= Type: GPIO GPIO: INT_13 ====== WatchDog ============== Type: REG </file> ==== Bootloader ==== U-Boot is used as bootloader for this device, and has access to a modifiable u-boot-env partition. This can be used to store modified and custom environment variables. Some realtek-specific commands are also available: * ''rtk network on'': Configure the ethernet hardware inside the bootloader (not enabled on boot). ===== References ===== * [[https://www.netgear.com/support/product/gs108Tv3.aspx | Product support page ]] gs108tv3.txt Last modified: 2021/05/01 04:43by raylynnknight
