The commit 04e91631e0 ("om-watchdog: add support for Teltonika RUT5xx

connected watchdog on the Teltonika RUT5xx.
But this daemon has massive problems since commit 30f61a34b4
("base-files: always use staged sysupgrade"). The process will always be
stopped on sysupgrades. If the sysupgrade takes slightly longer, the
watchdog is not triggered at the correct time and thus the sysupgrade will
interrupted hard by the watchdog sysupgrade. And this hard interrupt can
easily brick the device when there is no fallback (dual-boot, ...).

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.

- RESET button recovery with original U-Boot

Currently, ramips target defines 0x7b0000 as default IMAGE_SIZE
for all devices in ramips target, i.e. this will be set if a

From 92 devices using that default due to a "missing" IMAGE_SIZE,
14 were incorrect by a small amount (i.e. still "8M" flash) and
12 were completely off ("16M", "4M", ...).
This patch thus removes the _default_ IMAGE_SIZE and defines
IMAGE_SIZE for each device individually. This should indicate to
people supporting new devices that this parameter has to be cared
about.

In ramips, there are the following predefined values for IMAGE_SIZE

ralink_default_fw_size_8M 8060928 7872k 0x7B0000
ralink_default_fw_size_16M 16121856 15744k 0xF60000
ralink_default_fw_size_32M 33226752 32448k 0x1FB0000
Out of those, the "16M" value is obviously odd, as it provides more
room for the remaining partitions than the tree others.
Of the devices in all subtargets, there are actually > 50 that have
a firmware partition with 0xFB0000 size, while only 5 (!) have
0xF60000. From the former, many are set to
ralink_default_fw_size_16M anyway, although it is wrong at the
present point.
Consequently, it makes sense to change ralink_default_fw_size_16M
to 0xFB0000, and to update IMAGE_SIZE for the 5 devices with

The ramdisk image (not the squashfs sysupgrade image) can be flashed
through the web interface (named "GoAhead") of the factory firmware.
However, as the factory firmware does not cleanly unmount the rootfs
before flashing, the device may hang instead of rebooting after
successful write. Power cycling the device gets you in OpenWrt where
the squashfs image may be flashed through normal sysupgrade procedure.
