This pull request is based on
- the discussions in https://forum.openwrt.org/t/adding-openwrt-support-for-linksys-mr6350
- https://github.com/openwrt/openwrt/pull/11405 which added support for similar devices.
Device Specs:
- IPQ4019
- Quad Core CPU
- 256 MB RAM
- 256 MB FLASH
- 4 LAN ports, 1 WAN port
- 2.4GHz (802.11n) and 5GHz (802.11c) wifi
- 3 LEDs (Red, blue, green) which are routed to one indicator at the top of the case
- 2 buttons (Reset, WPS)
Disassembling the device:
- There are 4 screws at the bottom of the device which must be removed
- Two are under the fron rubber feets
- Two are under the labels in the back (corner next to the rear rubber feets)
Serial interface:
- The serial interface is already populated on the device with a 6-pin header
- Pin 1 is next to the heatsink
- Pinout: 1: 3.3V, 2: TX, 3: RX, 4: unknown, 5: GND, 6: GND
- Settings: 115200, 8N1
Migrating to OpenWrt requires multiple steps:
- Load and boot the initramfs image
- Adapt U-Boot settings to support bigger kernels
- Flash the sysupgrade image
Load and boot initramfs:
- Connect serial interface
- Set up a TFTP server on IP 192.168.1.254
- Copy openwrt-ipq40xx-generic-linksys_mr6350-initramfs-zImage.itb to TFTP server
- Rename file to
C0A80101.img
- Boot up the device and stop in U-Boot
- Run the following U-Boot commands after a link has been established:
tftp
bootm
- Initramfs image is started now.
Adapt U-Boot settings to support bigger kernels:
- Run "fw_printenv" in the initramfs image after booting
- There should be an entry kernsize=300000 which indicates the maximum size for the kernel is 3MB
- Execute "fw_setenv kernsize 500000" to increase the max kernel size to 5MB
- Check that the change are applied with "fw_printenv"
Flash the sysupgrade image:
- Default sysupgrade routine either with a initramfs image containing LuCI or via command line.
Revert back to OEM firmware:
- Only tested with FW_MR6350_1.1.3.210129_prod.img
- Flash the OEM firmware via sysupgrade
- Forced update is required
