Leon M. Busch-George 20e4a18feb mediatek: filogic: add support for Cudy M3000 v1 ... Hardware: SoC: MT7981b RAM: 256 MB Flash: 128 MB SPI NAND Ethernet: 1x 2.5Gbps (rtl8221b) 1x 1Gbps (integrated phy) WiFi: 2x2 MT7981 Buttons: Reset, WPS LED: 1x multicolor Solder on UART: - remove rubber ring on the bottom - remove screws - pull up the cylinder, maybe help by push on an ethernet socket with a screwdriver - remove the (3) screws holding the board in the frame - remove the board from the frame to get to the screws for the silver, flat heat shield - remove the (3) screws holding the heat shield - solder UART pins to the back of the board - make sure to have the pins point out on side with the black, finned heat spread - the markings for the pins are going to be below the silver heat shield - Vcc is not needed If you don't intend on using the UART outside of the installation process, you might not want to solder: - carefully scrape off the thin layer of epoxy on the holes (not the copper) - place your pin header with the UART attached in the holes - the pins, starting with the one closest to the socket: - Vcc (not required) - GND - RX - TX - either wedge the header or hold it with your fingers so that the pins stay in contact with the board Installation (UART): - attach an Ethernet cable to the 1Gbps port (black) on the router - hold the reset button while powering the router - press CTRL-C or wait for the timeout to get to the U-Boot prompt - prepare a TFTP server on the network to supply ..-initramfs-kernel.bin - use 'tftpboot' in the U-Boot shell to pull the image - boot the image using 'bootm' - push the ..-sysupgrade to the router using your preferred method - perform the upgrade with 'sysupgrade -n' There is a recovery mechanism that involves fetching a file called 'recovery.bin' but that is not understood yet.
