Support for Linksys LGS310MPC (PoE variant of LGS310C, 256MB DRAM)

For Developers
1

Hello,

I would like to request support for the Linksys LGS310MPC managed switch.

After inspecting the hardware, this device appears to be nearly identical to the supported Linksys LGS310C, with the following differences:

  • LGS310MPC includes PoE
  • DRAM size: 256 MB
  • PCB layout, SoC and switch silicon appear identical to LGS310C (except PoE power section)

Because LGS310C is already supported in OpenWrt (Realtek target), I believe LGS310MPC might be a close sibling device requiring minimal adjustments.

Hardware details (LGS310MPC)

  • Model: Linksys LGS310MPC
  • DRAM: 256 MB
  • Flash: same as LGS310C
  • SoC: appears identical to LGS310C (Realtek RTL93xx family)
  • Switch silicon: same as LGS310C
  • Bootloader: same behavior as LGS310C
  • PCB: identical except PoE power delivery section

I can provide:

  • PCB photos
  • chip markings
  • serial bootlog
  • flash layout dump
  • test builds

You've got the device, so you need to be the one adding support for it. Please see

You can try to TFTP boot the LGS310C initramfs image and check if it is compatible. Don't flash it unless you are sure that the flash layout matches. If you're lucky, PoE is implemented using one of the supported MCUs, so you need to add a serial port to the DTS and build realtek-poe. You can examine the PoE board to see if the ICs are supported.
