Davide Fioravanti	213250b56b	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 Signed-off-by: Davide Fioravanti <pantanastyle@gmail.com> [cosmetic DTS changes, remove TPLINK_HWREVADD := 0, do not use two phyXtpt at once, add missing buttons, minor commit message adjustments] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>	2020-03-18 14:25:38 +01:00
