The vendor flash layout of the Linksys E8450 is problematic as it uses
the SPI-NAND chip without any wear-leveling while at the same time
wasting a lot of space for padding.
Use an all-UBI layout instead, storing the kernel+dtb+squashfs in
uImage.FIT standard format in UBI volume 'fit', the read-write
overlay in UBI volume 'rootfs_data' as well as reduntant U-Boot
environments 'ubootenv' and 'ubootenv2', and a 'recovery'
kernel+dtb+initramfs uImage.FIT for dual-boot.
** WARNING **
THIS PROCEDURE CAN EASILY BRICK YOUR DEVICE PERMANENTLY IF NOT CARRIED
OUT VERY CAREFULLY AND EXACTLY AS DESCRIBED!
Step 0
* Configure your PC to have the static IPv4 address 192.168.1.254/24
* Provide bin/targets/mediatek/mt7622 via TFTP
Now continue EITHER with step 1A or 1B, depending on your preference
(and on having serial console wired up or not).
Step 1A (Using the vendor web interface (or non-UBI OpenWrt install))
In order to update to the new bootloader and UBI-based firmware,
use the web browser of your choice to open the routers web-interface
accessible on http://192.168.1.1
* Navigate to
'Configuration' -> 'Administration' -> 'Firmware Upgrade'
* Upload the file
openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
and proceed with the upgrade.
* Once OpenWrt comes up, use SCP to upload the new bootloader files to
/tmp on the router:
*-mt7622-linksys_e8450-ubi-preloader.bin
*-mt7622-linksys_e8450-ubi-bl31-uboot.fip
* Connect via SSH as you will now need to replace the bootloader in
the Flash.
ssh root@192.168.1.1
(the usual warnings)
* First of all, backup all the flash now:
for mtd in /dev/mtdblock*; do
dd if=$mtd of=/tmp/$(basename $mtd);
done
* Then use SCP to copy /tmp/mtdblock* from the router and keep them
safe. You will need them should you ever want to return to the
factory firmware!
* Now flow the uploaded files:
mtd -e /dev/mtd0 write /tmp/*linksys_e8450-ubi-preloader.bin /dev/mtd0
mtd -e /dev/mtd1 write /tmp/*linksys_e8450-ubi-bl31-uboot.fip /dev/mtd1
If and only if both writes look like the completed successfully
reboot the router. Now continue with step 2.
Step 1B (Using the vendor bootloader serial console)
* Use the serial to backup all /dev/mtd* devices before using the
stock firmware (you got root shell when connected to serial).
* Then reboot and select 'U-Boot Console' in the boot menu.
* Copy the following lines, one by one:
tftpboot 0x40080000 openwrt-mediatek-mt7622-linksys_e8450-ubi-preloader.bin
tftpboot 0x40100000 openwrt-mediatek-mt7622-linksys_e8450-ubi-bl31-uboot.fip
nand erase 0x0 0x180000
nand write 0x40080000 0x0 0x180000
reset
Now continue with step 2
Step 2
Once the new bootchain comes up, the loader will initialize UBI and the
ubootenv volumes. It will then of course fail to find any bootable
volume and hence resort to load kernel via TFTP from server
192.168.1.254 while giving itself the address 192.168.1.1
The requested file is called
openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb
and your TFTP server should provide exactly that :)
It will be written to UBI as recovery image and booted.
You can then continue and flash the production OS image, either
by using sysupgrade in the booted initramfs recovery OS, or by using
the bootloader menu and TFTP.
That's it. Go ahead and mess around with a bootchain built almost
completely from source (only DRAM calibration blobs are fitted in bl2,
and the irreplacable on-chip ROM loader remains, of course).
And enjoy U-Boot built with many great features out-of-the-box.
You can access the bootloader environment from within OpenWrt using the
'fw_printenv' and 'fw_setenv' commands. Don't be afraid, once you got
the new bootchain installed the device should be fairly unbrickable
(holding reset button before and during power-on resets things and
allows reflashing recovery image via TFTP)

Build U-Boot for the Linksys E8450 in order to have support for UBI.
The loader has a default environment with scripts handling the reset
button as well as fall-back to recovery firmware. If the loader comes
up without a valid environment found in UBI, it will automatically
make sure UBI is formatted and create a new environment and proceed
to load recovery firmware (either from UBI or via TFTP if recovery is
corrupted or unavailable).
If the button is held down during power-on, the yellow status LED
turns on and the bootloader environment is reset to factory defaults.
If the button is released at this point, the recovery firmware (if
existing) is loaded from UBI and booted.
If the button is continously held down even beyond the point that
the yellow LED turned on, the loader will try to load the recovery
firmware via TFTP from server 192.168.1.254, write it to UBI and
boot.

The CPU_MIPS64 and CPU_MIPS32 variables are supposed to be able to
distinguish broadly between 64-bit and 32-bit MIPS CPUs. However, they
weren't selected by the specialty CPUs, Octeon and Loongson, which meant
it was possible to hit a weird state of:
MIPS=y, CONFIG_64BIT=y, CPU_MIPS64=n
This commit rectifies the issue by having CPU_MIPS64 be selected when
the missing Octeon or Loongson models are selected.
In particular, this affects our octeonplus target.

To the vast majority of the users, wireguard-tools are not useful
without the underlying kernel module. The cornercase of only generating
keys and not using the secure tunnel is something that won't be done on
an embedded OpenWrt system often. On the other hand, maintaining a
separate meta-package only for this use case introduces extra
complexity. WireGuard changes for Linux 5.10 remove the meta-package.
So let's make wireguard-tools depend on kmod-wireguard
to make WireGuard easier to use without having to install multiple
packages.

Rather than using the clunky, old, slower wireguard-linux-compat out of
tree module, this commit does a patch-by-patch backport of upstream's
wireguard to 5.4. This specific backport is in widespread use, being
part of SUSE's enterprise kernel, Oracle's enterprise kernel, Google's
Android kernel, Gentoo's distro kernel, and probably more I've forgotten
about. It's definately the "more proper" way of adding wireguard to a
kernel than the ugly compat.h hell of the wireguard-linux-compat repo.
And most importantly for OpenWRT, it allows using the same module
configuration code for 5.10 as for 5.4, with no need for bifurcation.
These patches are from the backport tree which is maintained in the
open here: https://git.zx2c4.com/wireguard-linux/log/?h=backport-5.4.y

ZTE MF283+ is a dual-antenna LTE category 4 router, based on Ralink
RT3352 SoC, and built-in ZTE P685M PCIe MiniCard LTE modem.
Hardware highlighs:
- CPU: MIPS24KEc at 400MHz,
- RAM: 64MB DDR2,
- Flash: 16MB SPI,
- Ethernet: 4 10/100M port switch with VLAN support,
- Wireless: Dual-stream 802.11n (RT2860), with two internal antennas,
- WWAN: Built-in ZTE P685M modem, with two internal antennas and two
switching SMA connectors for external antennas,
- FXS: Single ATA, with two connectors marked PHONE1 and PHONE2,
internally wired in parallel by 0-Ohm resistors, handled entirely by
internal WWAN modem.
- USB: internal miniPCIe slot for modem,
unpopulated USB A connector on PCB.
- SIM slot for the WWAN modem.
- UART connector for the console (unpopulated) at 3.3V,
pinout: 1: VCC, 2: TXD, 3: RXD, 4: GND,
settings: 57600-8-N-1.
- LEDs: Power (fixed), WLAN, WWAN (RGB),
phone (bicolor, controlled by modem), Signal,
4 link/act LEDs for LAN1-4.
- Buttons: WPS, reset.
Installation:
As the modem is, for most of the time, provided by carriers, there is no
possibility to flash through web interface, only built-in FOTA update
and TFTP recovery are supported.
There are two installation methods:
(1) Using serial console and initramfs-kernel - recommended, as it
allows you to back up original firmware, or
(2) Using TFTP recovery - does not require disassembly.
(1) Using serial console:
To install OpenWrt, one needs to disassemble the
router and flash it via TFTP by using serial console:
- Locate unpopulated 4-pin header on the top of the board, near buttons.
- Connect UART adapter to the connector. Use 3.3V voltage level only,
omit VCC connection. Pin 1 (VCC) is marked by square pad.
- Put your initramfs-kernel image in TFTP server directory.
- Power-up the device.
- Press "1" to load initramfs image to RAM.
- Enter IP address chosen for the device (defaults to 192.168.0.1).
- Enter TFTP server IP address (defaults to 192.168.0.22).
- Enter image filename as put inside TFTP server - something short,
like firmware.bin is recommended.
- Hit enter to load the image. U-boot will store above values in
persistent environment for next installation.
- If you ever might want to return to vendor firmware,
BACK UP CONTENTS OF YOUR FLASH NOW.
For this router, commonly used by mobile networks,
plain vendor images are not officially available.
To do so, copy contents of each /dev/mtd[0-3], "firmware" - mtd3 being the
most important, and copy them over network to your PC. But in case
anything goes wrong, PLEASE do back up ALL OF THEM.
- From under OpenWrt just booted, load the sysupgrade image to tmpfs,
and execute sysupgrade.
(2) Using TFTP recovery
- Set your host IP to 192.168.0.22 - for example using:
sudo ip addr add 192.168.0.22/24 dev <interface>
- Set up a TFTP server on your machine
- Put the sysupgrade image in TFTP server root named as 'root_uImage'
(no quotes), for example using tftpd:
cp openwrt-ramips-rt305x-zte_mf283plus-squashfs-sysupgrade.bin /srv/tftp/root_uImage
- Power on the router holding BOTH Reset and WPS buttons held for around
5 seconds, until after WWAN and Signal LEDs blink.
- Wait for OpenWrt to start booting up, this should take around a
minute.
Return to original firmware:
Here, again there are two possibilities are possible, just like for
installation:
(1) Using initramfs-kernel image and serial console
(2) Using TFTP recovery
(1) Using initramfs-kernel image and serial console
- Boot OpenWrt initramfs-kernel image via TFTP the same as for
installation.
- Copy over the backed up "firmware.bin" image of "mtd3" to /tmp/
- Use "mtd write /tmp/firmware.bin /dev/mtd3", where firmware.bin is
your backup taken before OpenWrt installation, and /dev/mtd3 is the
"firmware" partition.
(2) Using TFTP recovery
- Follow the same steps as for installation, but replacing 'root_uImage'
with firmware backup you took during installation, or by vendor
firmware obtained elsewhere.
A few quirks of the device, noted from my instance:
- Wired and wireless MAC addresses written in flash are the same,
despite being in separate locations.
- Power LED is hardwired to 3.3V, so there is no status LED per se, and
WLAN LED is controlled by WLAN driver, so I had to hijack 3G/4G LED
for status - original firmware also does this in bootup.
- FXS subsystem and its LED is controlled by the
modem, so it work independently of OpenWrt.
Tested to work even before OpenWrt booted.
I managed to open up modem's shell via ADB,
and found from its kernel logs, that FXS and its LED is indeed controlled
by modem.
- While finding LEDs, I had no GPL source drop from ZTE, so I had to probe for
each and every one of them manually, so this might not be complete -
it looks like bicolor LED is used for FXS, possibly to support
dual-ported variant in other device sharing the PCB.
- Flash performance is very low, despite enabling 50MHz clock and fast
read command, due to using 4k sectors throughout the target. I decided
to keep it at the moment, to avoid breaking existing devices - I
identified one potentially affected, should this be limited to under
4MB of Flash. The difference between sysupgrade durations is whopping
3min vs 8min, so this is worth pursuing.
In vendor firmware, WWAN LED behaviour is as follows, citing the manual:
- red - no registration,
- green - 3G,
- blue - 4G.
Blinking indicates activity, so netdev trigger mapped from wwan0 to blue:wwan
looks reasonable at the moment, for full replacement, a script similar to
"rssileds" would need to be developed.
Behaviour of "Signal LED" in vendor firmware is as follows:
- Off - no signal,
- Blinking - poor coverage
- Solid - good coverage.
A few more details on the built-in LTE modem:
Modem is not fully supported upstream in Linux - only two CDC ports
(DIAG and one for QMI) probe. I sent patches upstream to add required device
IDs for full support.
The mapping of USB functions is as follows:
- CDC (QCDM) - dedicated to comunicating with proprietary Qualcomm tools.
- CDC (PCUI) - not supported by upstream 'option' driver yet. Patch
submitted upstream.
- CDC (Modem) - Exactly the same as above
- QMI - A patch is sent upstream to add device ID, with that in place,
uqmi did connect successfully, once I selected correct PDP context
type for my SIM (IPv4-only, not default IPv4v6).
- ADB - self-explanatory, one can access the ADB shell with a device ID
added to 51-android.rules like so:
SUBSYSTEM!="usb", GOTO="android_usb_rules_end"
LABEL="android_usb_rules_begin"
SUBSYSTEM=="usb", ATTR{idVendor}=="19d2", ATTR{idProduct}=="1275", ENV{adb_user}="yes"
ENV{adb_user}=="yes", MODE="0660", GROUP="plugdev", TAG+="uaccess"
LABEL="android_usb_rules_end"
While not really needed in OpenWrt, it might come useful if one decides to
move the modem to their PC to hack it further, insides seem to be pretty
interesting. ADB also works well from within OpenWrt without that. O
course it isn't needed for normal operation, so I left it out of
DEVICE_PACKAGES.

MediaTek targets always use U-Boot's modern uImage.FIT format which
allows bundling several blobs into a single file including hashes,
descriptions and more. In fact, we are already using that to bundle
the Flattened Device Tree blob with the kernel on this and many
other targets.
In the same fashion, we can now make use of the newly introduced
support for building seperate ramdisk to uImage.FIT with a dedicated
initrd blob checked and loaded by U-Boot instead of embedding the
cpio archive into the kernel itself.
This allows for having larger ramdisks, choosing ramdisk compression
independently of kernel compression (while only kernel is decompressed
by the bootloader) and for more easily replacing or modifying the
filesystem contained in an initramfs image.
