Just received both the Beryl 7 and Brume 3 which share the Mediatek 7987a.
Looking for guidance on flashing, testing, and adding these devices to the DB, as well as general status tracking in this thread.
If there's anything to consider beyond the existing guides, happy to read them! Thanks in advance for any eyes on this

There is a PR for the Brume3 that you can test:
main ← GLiNet-Tech:main
opened 01:41AM - 27 Jan 26 UTC
This patch adds support for GL.iNet MT5000.
The GL.iNet MT5000 is a gateway d… evice equipped with three 2.5G Ethernet ports, two of which are LAN ports and one is a WAN port. Currently, this submission does not support LAN-to-LAN communication; only WAN-to-LAN functionality is guaranteed to operate normally.
Hardware Specification:
- SoC: MediaTek MT7987A (Quad-core ARM Cortex-A53 2.0 GHz)
- RAM: 1024 MiB DDR4
- Flash: 8192 MiB EMMC
- Ethernet:
- 2x 10/100/1000/2500 Mbps LAN (Realtek RTL8366ub Switch)
- 1x 10/100/1000/2500 Mbps LAN (SoC internal PHY)
- Buttons: Reset,
- LEDs: 3x (Blue: Run, White: System, White: Vpn)
- UART: 115200 8n1 (VCC, RX, TX, GND)
Flash Layout:
- 0x0~0x4400 : GPT
- 0x400000~0x480000 : u-boot-env
- 0x480000~0x880000 : Factory
- 0x880000~0xa80000 : fip
- 0xa80000~0xc80000 : cfg
- 0xc80000~0xe80000 : log
- 0xe80000~0x2e80000 : kernel
- 0x2e80000~0x12a80000: rootfs
MAC Addresses (NVMEM):
- Base MAC located at Factory partition offset 0x4
- gmac1 (WAN) : Base - 2 (Label MAC)
- gmac0 (LAN) : Base - 1
Installation:
1. You can directly upgrade using the openwrt-mediatek-filogic-glinet_gl-mt5000-squashfs-sysupgrade.bin image on the official GL firmware upgrade page.
2. Access the device and use the sysupgrade command to upgrade.Note: When upgrading from official firmware, use the -n parameter to preserve no configuration.

Probably a showstopper:
Q: Does your GPL tar for the vendor firmware contains the source code of the Realtek switch driver?

mmm...you are probably right
I tried to search for datasheet on “Realtek RTL8366ub Switch”, but all I can find is RTL8366 or RTL8366SC-CG. Looks like this RTL8366ub switch chip is a new variant that cannot be easily found out there.
It appears someone from GL.iNET made a comment on GitHub that they are pursuing for opening the source code of RTL8366ub switch chip. Guess we’ll need to wait and see.
