ath79: add support for NEC Aterm WR8750N
NEC Aterm WR8750N is a 2.4/5 GHz band 11n (Wi-Fi 4) router, based on
AR9344.
Specification:
- SoC : Atheros AR9344
- RAM : DDR2 128 MiB (2x Hynix H5PS5162GFR-S6C)
- Flash : SPI-NOR 8 MiB (Macronix MX25L6406EMI-12G)
- WLAN : 2.4/5 GHz 2T2R
- 2.4 GHz : Atheros AR9344 (SoC)
- 5 GHz : Atheros AR9382
- Ethernet : 5x 10/100/1000 Mbps
- switch : Atheros AR8327
- LEDs/Keys (GPIO): 10x/4x
- note : all LEDs are controlled by ath9k chip (AR9382)
- UART : through-hole on PCB
- assignment : 3.3V, GND, NC, TX, RX from tri-angle marking
- settings : 9600n8
- USB : 1x USB 2.0 Type-A
- hub (internal): NEC uPD720114
- Power : 12 VDC, 1.5 A (Max. 16 W)
- Stock OS : NetBSD based
Flash instruction using initramfs-factory.bin image (StockFW WebUI):
1. Boot WR8750N with router mode normally
2. Access to the WebUI ("http://aterm.me/" or "http://192.168.0.1/") on
the device and open firmware update page ("ファームウェア更新")
3. Select the OpenWrt initramfs-factory.bin image and click update
("更新") button
4. After updating, the device will be rebooted and booted with OpenWrt
initramfs image
5. On the initramfs image, upload (or download) uboot.bin and
sysupgrade.bin image to the device
6. Replace the bootloader with a uboot.bin image
mtd write <uboot.bin image> bootloader
7. Perform sysupgrade with a sysupgrade.bin image
sysupgrade <sysupgrade image>
8. Wait ~120 seconds to complete flashing
Flash instruction using initramfs-factory.bin image (bootloader CLI):
1. Connect and open serial console
2. Power on WR8750N and interrupt bootloader by ESC key
3. Login to the bootloader CLI with a password "chiron"
4. Start TFTP server by "tftpd" command
5. Upload initramfs-factory.bin via tftp from your computer
example (Windows): tftp -i 192.168.0.1 PUT initramfs-factory.bin
6. Boot initramfs image by "boot" command
7. On the initramfs image, back up the stock bootloader and firmware if
needed
8. Upload (or download) uboot.bin and sysupgrade.bin image to the device
9. Replace the bootloader with a uboot.bin image
10. Perform sysupgrade with a sysupgrade.bin image
11. Wait ~120 seconds to complete flashing
Notes:
- All LEDs are connected to the GPIO controller on the ath9k chip
(AR9382) and controlled by it. Those LEDs are probed after probing of
ath9k chip, so they cannot be handled as status LEDs of OpenWrt while
booting.
- A reset pin of the internal USB hub is connected to the GPIO
controller of the ath9k chip, like LEDs above. That hub will be
detected after probing of the ath9k chip.
- The stock bootloader requires an unknown filesystem on firmware area
in the flash. Booting of OpenWrt from that filesystem cannot be
handled, so the bootloader needs to be replaced to mainline U-Boot
before OpenWrt installation.
MAC Addresses:
LAN : 1C:B1:7F:xx:xx:00 (config, 0x6 (hex))
WAN : 1C:B1:7F:xx:xx:01 (config, 0xc (hex))
2.4 GHz: 1C:B1:7F:xx:xx:02 (config, 0x0 (hex) / art, 0x1002 (hex))
5 GHz : 1C:B1:7F:xx:xx:03 (config, 0x12 (hex) / art, 0x5002 (hex))
