ramips: add support for Edimax RG21S
SoC: MediaTek MT7621AT dual-core @ 880MHz
RAM: 256M (Nanya NT5CC128M)
FLASH: 16MB (Macronix MX25L12835F)
WiFi: - 2.4GHz MediaTek MT7615N bgn
- 5GHz MediaTek MT7615N nac
Switch: SoC integrated Gigabit Switch (4 x LAN, 1 x WAN)
USB: No
BTN: Reset, WPS
LED: 4 red LEDs, indistinguishable when casing closed
UART: UART is present as Pads marked J1 on the PCB.
3.3V - RX - GND - TX / 57600-8N1
3.3V is the square pad
Installation
------------
Update the factory image via the OEM web-interface
(by default:http://192.168.1.1)
The sysupgrade image can be installed via TFTP from
the U-Boot bootloader. Connect ethernet port 2.
Signed-off-by: Birger Koblitz <m...@birger-koblitz.de>
---
v3: Update to DEVICE_VENDOR / DEVICE_MODEL in mt7621.mk
renamed .dts according to new conventions
Removed memory node from .dts
Correct image size
Whitespace fixes
v4: Added wifi0/1 labels to wifi nodes
Model name corrected in dts
Comments removed from .dts
v5: Corrected MT7615N PCI IDs
Unnecessary kernel-modules removed from image
v6: Removed unnecessary mtd-mac-address in .dts
Rebased to latest master
