The ... uh, I did a mistake in the commit message. You should assign your system IP 192.168.1.10, and requess will be coming from 192.168.1.1. May you fix that directly? Thanks a lot.

The GatoNetworks GDSP is a re-branded version of the R5000 5G Industrial router from Yinghua Technologies. The re-branded device comes with OpenWrt preinstalled, and an OpenWrt-based U-Boot bootloader version. While the flash layout has been kept compatible with the OpenWrt version found on the stock device (see [5]), the image format changed, making a bootloader upgrade necessary. Specifications: SoC: Mediatek MT7981BA RAM: 256MB Flash: SPI-NOR 32 MiB (Winbond W25Q256) WLAN: MT7976CN DBDC AX Wi-Fi Switch: MT7531AE (4x LAN Gigabit ports, 1x WAN Gigabit port) 5G: Quectel RM520N modem Watchdog: an external WDT connected to GPIO 6 is present and always running; the built-in Mediatek watchdog is also present and effective, but not used at the moment. This porting has been tested only with 1x 5G modems installed (the device supports up to two). Installation: Installation is possible via sysupgrade both in the stock device and re-branded version. However, in the former case, updating the bootloader is required. OpenWrt-based U-Boot Bootloader installation -------------------------------------------- The firmware flashed in the re-branded device at manifacturing time will flash an OpenWrt-based U-Boot bootloader with some extra recovery features (see [1]) at first boot. To update the bootloader, you need to install the mtd-rw module and insmod it: insmod mtd-rw i_want_a_brick=1 Then update relevant flash partitions: mtd erase u-boot-env mtd erase BL2 mtd erase FIP mtd write openwrt-mediatek-filogic-gatonetworks_gdsp-preloader.bin BL2 mtd write openwrt-mediatek-filogic-gatonetworks_gdsp-bl31-uboot.fip FIP And reboot, making sure all previous commands ran succesfully. If something goes wrong, you can recover your device via the mtk_uartboot tool. In my testing, it was possible to start the process even without (un)-plugging the device, may be handy for remote recovery. Installation from stock device and firmware ------------------------------------------- To install vanilla OpenWrt in the stock device (R5000 5G Industrial router from Yinghua Technologies) running the stock vendor firmware, you will need to update your bootloader as described in previous section. Remember to use -F (force upgrade) and -n (not keeping settings). U-Boot Recovery --------------- This procedure has been tested only with the OpenWrt-based U-boot bootloader. Assign your system static IP address 192.168.1.1 and start a TFTP server. The device will look for an initramfs image named openwrt-mediatek-filogic-gatonetworks_gdsp-initramfs-kernel.bin (so you may use openwrt/bin/targets/mediatek/filogic as root dir for your TFTP server). Power on the device while keeping the reset button pressed, until you see a TFTP request from 192.168.1.10. Your environment will be restored to it's default state. MAC addresses assignment ------------------------ MAC addresses are assigned slightly differently than in stock firmware. In particular, the 5 GHz Wi-Fi uses 2.4 GHZ MAC + 1, rather than reusing it with LA bit set as done in stock firmware. This MAC address is allocated to the device, so it can be used. The 2.4 GHz Wi-Fi MAC address is the label MAC. LAN MAC is used to set the special U-Boot environment ethaddr variable. device MAC address U-Boot env variable factory partition offset 2.4 GHz Wi-Fi :84 wifi_mac 0x4 5.8 GHz Wi-Fi :85 not present not present WAN :86 wan_mac 0x24 LAN :87 lan_mac 0x2A Notes ----- [1]: the OpenWrt-based U-Boot bootloader you will find installed in the re-branded device is configured to request for the initramfs image via TFTP for $gdsp_tftp_tries times before trying normal boot from NOR flash. Setting this U-Boot environment variable to 0x0 will disable the feature, which is not implemented in this patch. [2]: the exposed UART port is connected to ttyS1; the ttyS0 console port is not exposed. [3]: the provided bootloader environment has no provision for operating on BL2 and the FIP partitions. This is an intentional choice to make it (slightly) more difficult to brick the device. [4]: it seems GPIO 6 is used both for the "SYS" LED and external WDT. [5] BL2 expects to find FIP payload at a fixed offset, so some constraints apply.
