ramips: add support for Senao Engenius EPG600
FCC ID: A8J-EPG600
Engenius EPG600 is an indoor wireless router with
1 Gb ethernet switch, dual-band wireless,
internal antenna plates, USB, and phone lines (not supported)
this board is a Senao device:
the hardware is equivalent to EnGenius ESR600 (except for phone lines)
the software is Senao SDK which is based on openwrt and uboot
which uses the legacy Senao header with Vendor / Product IDs
to verify the firmware upgrade image.
**Specification:**
- MT7620 SOC MIPS 24kec, 2.4 GHz WMAC, 2x2
- RT5592N WLAN PCI chip, 5 GHz, 2x2
- QCA8337N Gb SW RGMII GbE, SW P0 -- SOC P5, 5 LEDs
- 40 MHz clock
- 16 MB FLASH MX25L12845EMI-10G
- 64 MB RAM NT5TU32M16
- UART console J2, populated
- USB 2.0 port direct to SOC
- 6 GPIO LEDs power, 2G, 5G, wps2g, wps5g, line
- 3 buttons reset, wps, "reg" (registeration)
- 4 antennas internal omni-directional plates
NOT YET SUPPORTED: VoIP
- Si3050-FT + Si3019-FT Voice DAA, SPI control, PCM data
- Phone Ports "TEL", "LINE" RJ11, 4P2C (2 pins)
**MAC addresses:**
MAC address labeled as MAC ADDRESS
MACs present in both wifi cal data and uboot environment
eth0.1/phy1 ---- *:82 rf 0x4
phy0 ---- *:83 factory 0x4
eth0.2 MAC *:b8 "wanaddr"
**Installation:**
Method 1: Firmware upgrade page:
(if you cannot access the APs webpage)
factory reset with the reset button
connect ethernet to a computer
OEM webpage at 192.168.0.1
username and password 'admin'
Navigate to gear icon, "Device Management", "Tools"
select the factory.dlf image
Upload and verify checksum
Method 2: Serial to upload initramfs:
Follow directions for TFTP recovery
upload and boot initramfs and do a sysupgrade
**TFTP recovery:**
Requires UART serial console, reset button does nothing
rename initramfs-kernel.bin to 'uImageEPG600'
make available on TFTP server at 192.168.99.8
power board, interrupt boot with "4"
execute `tftpboot` and `bootm` (with the load address)
**Return to OEM:**
Images from OEM are provided, but not compatible
with openwrt sysupgrade. So it must be modified.
Alternatively, back up all mtd partitions before flashing
**Note on switch registers:**
The necessary registers needed for the QCA8337 switch
can be read from interrupted boot (tftpboot, bootm)
by using the following lines in the switch driver ar8327.c
in the function 'ar8327_hw_config_of'
where 'qca,ar8327-initvals' is parsed from DTS
before the new register values are written:
pr_info("0x04 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD0_MODE));
pr_info("0x08 %08x\n", ar8xxx_read(priv, AR8327_REG_PAD5_MODE));
pr_info("0x0c %08x\n", ar8xxx_read(priv, AR8327_REG_PAD6_MODE));
pr_info("0x10 %08x\n", ar8xxx_read(priv, AR8327_REG_POWER_ON_STRAP));
