+Subject: ramips: add support for Ubiquiti EdgeRouter X-SFP
|
|
|
+
|
|
|
+This patch adds support for the Ubiquiti EdgeRouter X-SFP and
|
|
|
+improves support for the EdgeRouter X (PoE-passthrough).
|
|
|
+
|
|
|
+Specification:
|
|
|
+- SoC: MediaTek MT7621AT
|
|
|
+- Flash: 256 MiB
|
|
|
+- RAM: 265 MiB
|
|
|
+- Ethernet: 5 x LAN (1000 Mbps)
|
|
|
+- UART: 1 x UART on PCB (3.3V, RX, TX, GND) - 57600 8N1
|
|
|
+- EdgeRouter X:
|
|
|
+ - 1 x PoE-Passtrough (Eth4)
|
|
|
+ - powered by Wallwart or passive PoE
|
|
|
+- EdgeRouter X-SFP:
|
|
|
+ - 5 x PoE-Out (24V, passive)
|
|
|
+ - 1 x SFP (unknown status)
|
|
|
+ - powered by Wallwart (24V)
|
|
|
+
|
|
|
+Doesn't work:
|
|
|
+* SoC has crypto engine but no open driver.
|
|
|
+* SoC has nat acceleration, but no open driver.
|
|
|
+* This router has 2MB spi flash soldered in but MT
|
|
|
+ nand/spi drivers do not support pin sharing,
|
|
|
+ so it is not accessable and disabled. Stock
|
|
|
+ firmware could read it and it was empty.
|
|
|
+
|
|
|
+Installation
|
|
|
+
|
|
|
+via vendor firmware:
|
|
|
+- build an Initrd-image (> 3MiB) and upload the factory-image
|
|
|
+- initrd can have luci-mod-failsafe
|
|
|
+- flash final firmware via LuCI / sysupgrade on rebooted system
|
|
|
+
|
|
|
+via TFTP:
|
|
|
+- stop uboot into tftp-load into option "1"
|
|
|
+- upload factory.bin image
|
