Flashing

NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power.

Flashing OpenWrt

DSL will not work at all on devices with BCM63xx DSL chipset (due to unavailability of FLOSS driver for Broadcom chips). Consider this when choosing a device to buy, or when deciding to flash OpenWrt on your device because it is listed as supported. See Broadcom DSL, Unsupported: DSL modem and Broadcom BCM63xx for details.

ath79: add support for TP-Link Archer D7/D7b v1
TP-Link Archer D7 v1 is a dual-band AC1750 router + modem.
The router section is based on Qualcomm/Atheros QCA9558 + QCA9880.
The "DSL" section is based on BCM6318 but it's currently not supported.

The Archer D7b seems to differ from the Archer D7 only in the
partition table.

Router section - 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
4x 10/100/1000 Mbps Ethernet
7x LED, 2x button
UART header on PCB

Known issues:

- Broadband LED (missing GPIO - probably driven by the BCM6318)
- Internet LED (missing GPIO - probably driven by the BCM6318)
- WIFI LED (working only for one interface at a time, while in the
OEM firmware works for both wifi interfaces; thus, this patch does
not set a trigger by default)
- DSL not working (eth0)

UART connection
---------------
J1 HEADER (Qualcomm CPU)
. VCC
. GND
. RX
O TX

J41 HEADER (Broadcom CPU)
. VCC
. GND
. RX
O TX

The following instructions require a connection to the J1 UART header
and are tested for the Archer D7 v1.
For the Archer D7b v1, names should be changed accordingly.

Flash instructions under U-Boot, using UART
------------------------------------------
1. Press "tpl" to stop autobooting and obtain U-Boot CLI access.
2. Setup ip addresses for U-Boot and your tftp server.
3. Issue below commands:
tftpboot 0x81000000 openwrt-ath79-generic-tplink_archer-d7-v1-squashfs-sysupgrade.bin
erase 0x9f020000 +f90000
cp.b 0x81000000 0x9f020000 0xf90000
reset

Initramfs instructions under U-Boot for testing, using UART
----------------------------------------------------------
1. Press "tpl" to stop autobooting and obtain U-Boot CLI access.
2. Setup ip addresses for U-Boot and your tftp server.
3. Issue below commands:
tftpboot 0x81000000 openwrt-ath79-generic-tplink_archer-d7-v1-initramfs-kernel.bin
bootm 0x81000000
4. Here you can backup the original firmware and/or flash the sysupgrade openwrt if you want

Restore the original firmware
-----------------------------
0. Backup every partition using the OpenWrt web interface
1. Download the OEM firmware from the TP-Link website
2. Extract the bin file in a folder (eg. Archer_D7v1_1.6.0_0.9.1_up_boot(160216)_2016-02-16_15.55.48.bin)
3. Remove the U-Boot and the Broadcom image part from the file.
Issue the following command:
dd if="Archer_D7v1_1.6.0_0.9.1_up_boot(160216)_2016-02-16_15.55.48.bin" of="Archer_D7v1_1.6.0_0.9.1_up_boot(160216)_2016-02-16_15.55.48.bin.mod" skip=257 bs=512 count=31872
4. Double check the .mod file size. It must be 16318464 bytes.
5. Flash it using the OpenWrt web interface. Force the update if needed.
WARNING: Remember to NOT keep settings.

5b. (Alternative to 5.) Flash it using the U-Boot and UART connection.
Issue below commands in the U-Boot:
tftpboot 0x81000000 Archer_D7v1_1.6.0_0.9.1_up_boot(160216)_2016-02-16_15.55.48.bin.mod
erase 0x9f020000 +f90000
cp.b 0x81000000 0x9f020000 0xf90000
reset
