The flash procedure is similar to the Xiaomi AX6000 router. Load openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-initramfs-recovery.itb from original Zyxel U-Boot: tftpboot openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-initramfs-recovery.itb bootm 0x46000000 Load mtd-rw insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1 Format ubi and create ubootenv partitions ubidetach -p /dev/mtd5; ubiformat /dev/mtd5 -y; ubiattach -p /dev/mtd5 ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB Copy openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-initramfs-recovery.itb to /tmp and create recovery partition. If your recovery image is larger than 10MiB, size the recovery partition accordingly to make it fit. ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB ubiupdatevol /dev/ubi0_2 openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-initramfs-recovery.itb Copy preloader and uboot to /tmp and write them in the mtd mtd write /tmp/openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-preloader.bin bl2 mtd write /tmp/openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-bl31-uboot.fip fip Now write the firmware: sysupgrade -n /tmp/openwrt-mediatek-filogic-zyxel_ex5601-t0-ubootmod-squashfs-sysupgrade.itb To create a correct BL2, I had to add a profile for 'spim:4k+256' as I could not find a way to value the variable 'NAND_TYPE'. Features and fixes from hitech95 tree has been squashed, I'm attaching his commit message: The Power LED was not working correctly and not reacting to the boot process and statuses. The board has space (footprint) for an unpopulated Zigbee chip, while we dont know the device model having this chip populated we have to assure that the common dts doesnt enable interfaces that share pins with such device. In this instance the PCIe and the uart1 and uart2 are disabled. Some of the control PCIE pins seems to be used for the Zigbee chip, UART1 seems to be used as a flash port while UART2 should be the main comunication interface of Zigbee chip. The Zigbee chip should be a EFR32MG21. But the pins used for UART seems to be not on standard PINS used by other adapters. So it cannot run firmwares shared on the web. But it should be possible to build a custom firmware with the corrtect pinmux. This commit also contains the following squashed commit from hitech95 - mediatek: fix sysupgrade for Zyxel EX7601-T0 ubootmod Changes and fixes added in common board: - added aliases for boot status leds. - added aliases for the mac-label-device. - added pin claims for core features (MDIO and UART 0) - added default LEDs configuration (01_leds) - added default network configuration (02_network) - added missing kmod-usb3 module for USB3 - fixed LED names - fixed reset pin for SLIC chip - removed unused pinmux configurations and devices - fix LAN (switch) port numbering - using nvmem cells for wifi eeprom, dropping deprecated "mediatek,mtd-eeprom" - proper factory partition and mac address handling - cleaned up spi_nand sections and partition Changes and fixxes added in stock layout: - added NMBM, if u-boot has it, the kernel must be informed.
