Belkin RT3200 / Linksys E8450¶
Three units in the lab (belkin_rt3200_1, belkin_rt3200_2, belkin_rt3200_3). Same hardware sold under Belkin (RT3200) and Linksys (E8450) brands. Primary DUT for LibreMesh CI.
Hardware¶
| Attribute | Detail |
|---|---|
| SoC | MediaTek MT7622BV (dual Cortex-A53 @ 1.35 GHz) + MT7915E (Wi-Fi 6) |
| Architecture | ARM64 |
| RAM | 512 MB DDR3 |
| Flash | 128 MB SPI-NAND (UBI layout on OpenWrt) |
| Ethernet | 5 × 1 GbE (1 WAN + 4 LAN) |
| Wi-Fi | Dual-band AX3200 (2.4 GHz 2×2 + 5 GHz 4×4) |
| USB | 1 × USB 2.0 |
| OpenWrt target | mediatek/mt7622 — profile linksys_e8450-ubi |
Lab placement¶
| Place name | Rack slot | VLAN (isolated) | VLAN (mesh) |
|---|---|---|---|
belkin_rt3200_1 |
Slot 1 | 100 | 200 |
belkin_rt3200_2 |
Slot 2 | 101 | 200 |
belkin_rt3200_3 |
Slot 3 | 102 | 200 |
Power is controlled via Arduino relay. Serial console via USB-to-serial adapter connected to the host.
Firmware¶
OpenWrt uses UBI layout on this device — the standard sysupgrade image does not apply. Use the -initramfs-kernel.bin for testing (TFTP boot, no flash write).
linksys_e8450-ubi-initramfs-kernel.bin # OpenWrt
lime-linksys_e8450-ubi-initramfs-kernel.bin # LibreMesh
TFTP path: /srv/tftp/belkin_rt3200_N/ where N is 1, 2 or 3.
Running tests¶
# Single unit — OpenWrt base tests

LG_IMAGE=/srv/tftp/belkin_rt3200_1/linksys_e8450-ubi-initramfs-kernel.bin \

SSH shortcut (after test boot):
ssh dut-belkin-rt3200-1 # alias defined in ~/.ssh/config
CI¶
CI job name pattern: test-firmware (belkin_rt3200_N / RELEASE)
Results published to: docs/ci-results/results/physical/belkin_rt3200_N-RELEASE/report.xml
Known issues¶
- UBI migration must be done once before any initramfs test if the device was previously flashed with the non-UBI image. See OpenWrt TOH for the procedure.
- Serial baud rate: 115200.
