This patch adds support for the Linksys EA7500 V1 router.
Specification:
- CPU: Qualcomm IPQ8064
- RAM: 256MB
- Flash: NAND 128MB
- WiFi: QCA9982 an+ac + QCA9983 bgn
- Ethernet: 5 GBE Ports (WAN+ 4xLAN) (QCA8337)
- USB: 1x USB 3.0 1x USB2.0
- Serial console: RJ-45 115200 8n1 (1V8 Voltage level)
- 2 Buttons
- 1 LED
Known issues:
- Some devices won't flash via web gui
Installation:
- Newer stock images doesn't allow to install custom firmware.
- Please downgrade software to 1.1.2 version. Official firmware:
https://downloads.linksys.com/downloads/firmware/FW_EA7500_1.1.2.172843_prod.gpg.img
- Do it two times to downgrade all stored images.
- Apply factory image via web-gui.
Serial + TFTP method:
- downgrade to 1.1.2 two times
- connect ehternet and serial cable
- set ip address of tftp server to 192.168.1.254
- put openwrt factory image to tftp folder and rename it to macan.bin
- stop device while booting in u-boot
- run command: "run flashimg"
- run command: "setenv boot_part 1"
- run command "saveenv"
- reset
Back to stock:
- Please use old non-gpg image like this 1.1.2:
https://downloads.linksys.com/downloads/firmware/FW_EA7500_1.1.2.172843_prod.img
- ssh to router and copy image to tmp
- use sysupgrade -n -F
