Subject: ar71xx: add support for TP-LINK Archer C7 v4
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=df8b54171c32b416ab6d660025edeec16bcb06e7;p=project%2Ffirmware-utils.git

ar71xx: add support for TP-LINK Archer C7 v4

TP-Link Archer C7 v4 is a dual-band AC1750 router, based on Qualcomm/Atheros
QCA9561+QCA9888.

Specification:

- 775/650/258 MHz (CPU/DDR/AHB)
- 128 MB of RAM (DDR2)
- 16 MB of FLASH (SPI NOR)
- 3T3R 2.4 GHz
- 3T3R 5 GHz
- 5x 10/100/1000 Mbps Ethernet
- 7x LED, 2x button
- UART header on PCB

Flash instruction:
1. Upload lede-ar71xx-generic-archer-c7-v4-squashfs-factory.bin via Web interface

Flash instruction using TFTP recovery:
1. Set PC to fixed ip address 192.168.0.66
2. Download lede-ar71xx-generic-archer-c7-v4-squashfs-factory.bin
and rename it to ArcherC7v4_tp_recovery.bin
3. Start a tftp server with the file tp_recovery.bin in its root directory
4. Turn off the router
5. Press and hold Reset button
6. Turn on router with the reset button pressed and wait ~15 seconds
7. Release the reset button and after a short time
the firmware should be transferred from the tftp server
8. Wait ~30 second to complete recovery.

Flash instruction under U-Boot, using UART:

1. tftp 0x81000000 lede-ar71xx-...-sysupgrade.bin
2. erase 0x9f040000 +$filesize
3. cp.b $fileaddr 0x9f040000 $filesize
4. reset
