This pull request is based on - the discussions in https://forum.openwrt.org/t/support-for-the-linksys-mr9000 Device Specs: - Router is similar to EA8300 but with 512MB RAM and changed GPIOs - IPQ4019 - Quad Core CPU - 512 MB RAM - 256 MB FLASH - 4 LAN ports, 1 WAN port - 1x2.4GHz (802.11n) and 2x5GHz (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 T10 screws at the bottom of the device which must be removed - All 4 screws are located under the rubber feet Serial interface: - The serial interface is already populated on the device with a 5-pin header - Pinout from front to back: 1:GND, 2: unknown, 3: RX, 4: TX, 5: VCC - Settings: 115200, 8N1 MAC address layout: - Same as on MR8300 - MAC address is stored in the "devinfo" partition (entry "hw_mac_addr") - The MAC address on the label is identical with the one in the devinfo partition - The MAC address on the label is the WAN MAC address - LAN MAC address is the one from the label + 1 - Wifi (2.4GHz) MAC is the one from the label + 2 - Wifi (1st 5GHz) MAC is the one from the label + 3 - Wifi (2nd 5GHz) MAC is the one from the label + 4 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_mr9000-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: - Flash the OEM firmware via sysupgrade - Forced update is required Signed-off-by: Karsten Rehn <rekados@posteo.de> Signed-off-by: Roland Reinl <reinlroland+github@gmail.com> Link: https://github.com/openwrt/openwrt/pull/22744 Signed-off-by: Robert Marko <robimarko@gmail.com>
