From 9887afb1afcf387f6892315413e610a6816df463 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Tue, 25 Jul 2017 13:32:47 +0200 Subject: 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 Signed-off-by: Felix Fietkau --- .../files/arch/mips/ath79/mach-archer-c7-v4.c | 260 +++++++++++++++++++++ 1 file changed, 260 insertions(+) create mode 100644 target/linux/ar71xx/files/arch/mips/ath79/mach-archer-c7-v4.c (limited to 'target/linux/ar71xx/files/arch/mips/ath79/mach-archer-c7-v4.c') diff --git a/target/linux/ar71xx/files/arch/mips/ath79/mach-archer-c7-v4.c b/target/linux/ar71xx/files/arch/mips/ath79/mach-archer-c7-v4.c new file mode 100644 index 0000000000..64955c7994 --- /dev/null +++ b/target/linux/ar71xx/files/arch/mips/ath79/mach-archer-c7-v4.c @@ -0,0 +1,260 @@ + +/* + * Atheros ARCHER_C7 reference board support + * + * Copyright (c) 2017 Felix Fietkau + * Copyright (c) 2014 The Linux Foundation.
