mediatek: filogic: add support for GatoNetworks GDSP
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.
