TP-Link TL-SG2210P v3

The TP-Link TL-SG2210P v3 is an RTL8380M based switch with two SFP slots, and PoE 802.3af on all eight RJ-45 ports.

None at this time.

→ Install OpenWrt (generic explanation)

Please add the installation procedure here.

There is no known way to install OpenWRT from the OEM firmware. Use the TFTP method below.

→ generic.flashing.tftp

The footprints R27 (0201) and R28 (0402) are not populated. To enable serial console, 50 ohm resistors should be soldered -- any value from 0 ohm to 50 ohm will work. R27 can be replaced by a solder bridge.

The u-boot firmware drops to a TP-Link specific “BOOTUTIL” shell at 38400 baud. There is no known way to exit out of this shell, and no way to do anything useful.

Ideally, one would trick the bootloader into flashing the sysupgrade image first. However, if the image exceeds 6MiB in size, it will not work. The sysupgrade image can also be flashed. To install OpenWrt:

Prepare a tftp server with: 1. server address: 192.168.0.146 2. the image as: “uImage.img”

Power on device, and stop boot by pressing any key. Once the shell is active: 1. Ground out the CLK (pin 16) of the ROM (U7) 2. Select option “3. Start” 3. Bootloader notes that “The kernel has been damaged!” 4. Release CLK as sson as bootloader thinks image is corrupted. 5. Bootloader enters automatic recovery -- details printed on console 6. Watch as the bootloader flashes and boots OpenWrt.

# Crash course on LED controller:
# -------------------------------
#
# From a software perspective, the device has 11 groups with (3) LEDs each.
# We're trying to map the network ports to the LEDs:
#  ______
# |      |
# | 20-1 |
# |______|                    ______ ______ ______ ______ ______ ______ ______ ______

# The port numbering is flexible, but the ordering is fixed. The 'led_p_en_ctrl'
# register is a bitmask that controls which switch ports send status data.
# In this example, Enabling the desired ports results in the bitmask 0x0510ff00
# If there are more bits set than LED groups the extra (LSB) bits are discarded.
#
# LED[0] and LED[1] are bi-color LEDS
#     - LED[0] = amber, LED[1] = green
#     - Both on or both off turns off the LED
# 0xef: Turn LED1 on 1G, LED 0 on 100M.
#
# Switch port 20 is not used. The LEDs for port 20 are thus switched to manual
# mode by writing (1 << 20) bitmask in led0_sw_p_en_ctrl, and led0_sw_p_en_ctrl.
#
# LED[2] in each group is used for PoE or other functions, so they are all set
# to manual mode via the 'led2_sw_p_en_ctrl' register.
