mediatek: add support for Imou HX21 This board is also as known as LC-HX3001 Hardware specification: SoC: MediaTek MT7981B 2x A53 Flash: Foresee F35SQA001G 128 MB SPI-NAND RAM: 256MB DDR3 Ethernet: 4x 10/100/1000 Mbps Switch: MediaTek MT7531AE WiFi: MediaTek MT7976C Button: Reset, Mesh Power: DC 12V 1A Gain SSH access: Method 1: 1. Connect UART Adapter to the router 2. UART pins are enabled, set the root password with passwd command start the dropbear instance on port 22 Method 2: 1. Login into web interface, and restore the router with SSH enabled configuration. 2. After reboot Default Web interface password will be 12345678 SSH password is empty Flash instructions: 1. Connect to HX21, backup everything, especially 'Factory' part. 3. Write new FIP: mtd write openwrt-mediatek-filogic-hx_21-bl31-uboot.fip FIP 4. Set static IP on your PC: IP 192.168.1.254/24, GW 192.168.1.1 5. Serve OpenWrt initramfs image using TFTP server. 6. Wait for TFTP recovery to complete. 7. After OpenWrt has booted, perform sysupgrade. 8. To write new BL2 Install mtd-rw opkg update && opkg install kmod-mtd-rw insmod mtd-rw i_want_a_brick=1 mtd write openwrt-mediatek-filogic-imou_hx21-preloader.bin bl2
