This patch ports over support for the device from ar71xx.
SOC: AR7370 (Wasp - AR9344 rev2 0001974c)
RAM: Winbond W9725G6KB-25 32MiB
FLASH: Winbond 25Q64FVSIG 8MiB
WLAN: AR9380 Dual-Band 802.11abgn 3x3:3
INPUT: WPS, RESET button (hardware on/off toggle button)
LED: Power, LAN, WiFi, 3 RSSI-Leds (low, medium, high)
Serial: Header Next to the winbond flash chip (labeld JP1)
Pinout is GND - NC - RX - TX - 3V3 (JP1)
The Serial setting is 115200-8-N-1.
- Installation via uboot's upgrade command
0. attach serial cable
1. interrupt uboot and enter "upgrade code.bin" into
the u-boot prompt
ar7240> upgrade code.bin
2. rename openwrt...sysupgrade.bin to code.bin on PC
3. run a tftp-client on the PC
(shell)$ tftp 192.168.1.230
binary
put code.bin
4. wait for the device to finish
[...]
Copy buff to Flash from 0x9f040000 length 0x79f000
Copy to Flash... write addr: 9f040000
done
5. enter "go" in the u-boot prompt
ar7240> go
- TFTP ramdisk image boot from the uboot prompt
(tftp server defaults to serverip 192.168.1.254)
=> tftpboot 81000000 initramfs.bin
=> bootm
Tested and working:
- LEDs
- Buttons
- Ethernet
- Wi-Fi
- OpenWRT sysupgrade
For flashing and debricking information see:
<https://openwrt.org/toh/wd/rext>
Users coming from ar71xx can use sysupgrade too. But I highly
advise to no save the old configuration and start from a clean
state.
