Reduce spi-max-frequency for Xiaomi MI Router 4AG model
Xiaomi MI Router 4AG MTD uses two flash chips (no specific on router versions when produced from factory) - GD25Q128C and W25Q128BV.
These flash chips are capable of high frequency, but due to poor board design or manufacture process.
We are seeing the following errors in the linux kernel bootup:
`spi-nor spi0.0: unrecognized JEDEC id bytes: cc 60 1c cc 60 1c
spi-nor: probe of spi0.0 failed with error -2`
This causes the partitions not to be detected
`VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6`
Then creates a bootloop and a bricked router.
The solution to limit this race condition is to reduce the frequency from 80 mhz to 50 mhz.

DTS properties that match *-gpios are treated specially.
Use ngpios instead, as most GPIO drivers upstream do.
Fixes 5.10 DTS errors such as:

Youku YK-L1 has a huge storage space up to 32 MB. It is better to
use a higher spi clock to read or write serial nor flash chips.
Youku YK-L1 has Winbond w25q256fvfg on board that can support
104 MHz spi clock so 48 MHz is safe enough.
The real frequency can only be sysclk(580MHz ) /3 /(2^n) so 80 MHz
defined in dts file will set only 48 MHz in spi bus.

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.

The TP-Link EAP235-Wall is a wall-mounted, PoE-powered AC1200 access
point with four gigabit ethernet ports.
When connecting to the device's serial port, it is strongly advised to
use an isolated UART adapter. This prevents linking different power
domains created by the PoE power supply, which may damage your devices.
The device's U-Boot supports saving modified environments with
`saveenv`. However, there is no u-boot-env partition, and saving
modifications will cause the partition table to be overwritten. This is
not an issue for running OpenWrt, but will prevent the vendor FW from
functioning properly.
Device specifications:
* SoC: MT7621DAT
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (MT7603EN): b/g/n, 2x2
* Wireless 5GHz (MT7613BEN): a/n/ac, 2x2
* Ethernet: 4× GbE
* Back side: ETH0, PoE PD port
* Bottom side: ETH1, ETH2, ETH3
* Single white device LED
* LED button, reset button (available for failsafe)
* PoE pass-through on port ETH3 (enabled with GPIO)
Datasheet of the flash chip specifies a maximum frequency of 33MHz, but
that didn't work. 20MHz gives no errors with reading (flash dump) or
writing (sysupgrade).
Device mac addresses:
Stock firmware uses the same MAC address for ethernet (on device label)
and 2.4GHz wireless. The 5GHz wireless address is incremented by one.
This address is stored in the 'info' ('default-mac') partition at an
offset of 8 bytes.
From OEM ifconfig:
eth a4:2b:b0:...:88
ra0 a4:2b:b0:...:88
rai0 a4:2b:b0:...:89
Flashing instructions:
* Enable SSH in the web interface, and SSH into the target device
* run `cliclientd stopcs`, this should return "success"
* upload the factory image via the web interface
Debricking:
U-boot can be interrupted during boot, serial console is 57600 baud, 8n1
This allows installing a sysupgrade image, or fixing the device in
another way.
* Access serial header from the side of the board, close to ETH3,
pin-out is (1:TX, 2:RX, 3:GND, 4:3.3V), with pin 1 closest to ETH3.
* Interrupt bootloader by holding '4' during boot, which drops the
bootloader into its shell
* Change default 'serverip' and 'ipaddr' variables (optional)
* Download initramfs with `tftpboot`, and boot image with `bootm`
# tftpboot 84000000 openwrt-initramfs.bin
# bootm
Revert to stock:
Using the tplink-safeloader utility from the firmware-utils package,
TP-Link's firmware image can be converted to an OpenWrt-compatible
sysupgrade image:
$ ./staging_dir/host/bin/tplink-safeloader -B EAP235-WALL-V1 \
-z EAP235-WALLv1_XXX_up_signed.bin -o eap235-sysupgrade.bin
This can then be flashed using the OpenWrt sysupgrade interface. The
image will appear to be incompatible and must be force flashed, without
keeping the current configuration.
Known issues:
- DFS support is incomplete (known issue with MT7613)
- MT7613 radio may stop responding when idling, reboot required.
This was an issue with the ddc75ff704 version of mt76, but appears to
have improved/disappeared with bc3963764d.

This creates a DTSI for Xiaomi devices with 128M NAND.
This allows to consolidate the partitions and a few other nodes for
AC2100 family and Mi Router 3G.
Note that the Mi Router 3 Pro has 256M NAND and differently sized
partitions.

2 - TX
3 - GND
Console is 115200 8N1.
Boot
----
1. Connect to the serial console and connect power.
2. Double-press ESC when prompted
3. Set the fdt address
$ fdt addr $(fdtcontroladdr)
4. Remove the signature node from the control FDT
$ fdt rm /signature
5. Transfer and boot the OpenWrt initramfs image to the device.
Make sure to name the file C0A80114.img and have it reachable at
192.168.1.1/24
$ tftpboot; bootm
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt".
2. Update the bootloader environment.
$ fw_setenv devmode TRUE
$ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
fdt rm /signature; bootubnt"
$ fw_setenv bootcmd "run boot_openwrt"
3. Transfer the OpenWrt sysupgrade image to the device using SCP.
4. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
5. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock6
$ dd if=openwrt.bin of=/dev/mtdblock7
7. Reboot the device. It should boot into OpenWrt.
Below are the original installation instructions prior to the discovery
of "devmode=TRUE". They are not required for installation and are
documentation only.
The bootloader employs signature verification on the FIT image
configurations. This way, booting unauthorized image without patching
the bootloader is not possible. Manually configuring the bootcmd in the
U-Boot envronment won't work, as this is restored to the default value
if modified.
The bootloader is made up of three different parts.
1. The SPL performing early board initialization and providing a XModem
recovery in case the PBL is missing
2. The PBL being the primary U-Boot application and containing the
control FDT. It is LZMA packed with a uImage header.
3. A Ubiquiti standalone U-Boot application providing the main boot
routine as well as their recovery mechanism.
In a perfect world, we would only replace the PBL, as the SPL does not
perform checks on the PBLs integrity. However, as the PBL is in the same
eraseblock as the SPL, we need to at least rewrite both.
The bootloader will only verify integrity in case it has a "signature"
node in it's control device-tree. Renaming the signature node to
something else will prevent this from happening.
Warning: These instructions are based on the firmware intially
shipped with the device and potentially brick your device in a way it
can only be recovered using a SPI flasher.
Only (!) proceed if you understand this!
1. Extract the bootloader from the U-Boot partition using the OpenWrt
initramfs image.
2. Split the bootloader into it's 3 components:
$ dd if=bootloader.bin of=spl.bin bs=1 skip=0 count=45056
$ dd if=bootloader.bin of=pbl.uimage bs=1 skip=45056 count=143360
$ dd if=bootloader.bin of=ubnt.uimage bs=1 skip=188416
3. Strip the uImage header from the PBL
$ dd if=pbl.uimage of=pbl.lzma bs=64 skip=1
4. Decompress the PBL
$ lzma -d pbl.lzma --single-stream
The decompressed PBL sha256sum should be
d8b406c65240d260cf15be5f97f40c1d6d1b6e61ec3abed37bb841c90fcc1235
5. Open the decompressed PBL using your favorite hexeditor. Locate the
control FDT at offset 0x4CED0 (0xD00DFEED). At offset 0x4D5BC, the
label for the signature node is located. Rename the "signature"
string at this offset to "signaturr".
The patched PBL sha256sum should be
d028e374cdb40ba44b6e3cef2e4e8a8c16a3b85eb15d9544d24fdd10eed64c97
6. Compress the patched PBL
$ lzma -z pbl --lzma1=dict=67108864
The resulting pbl.lzma file should have the sha256sum
7ae6118928fa0d0b3fe4ff81abd80ecfd9ba2944cb0f0a462b6ae65913088b42
7. Create the PBL uimage
$ SOURCE_DATE_EPOCH=1607909492 mkimage -A mips -O u-boot -C lzma
-n "U-Boot 2018.03 [UniFi,v1.1.40.71]" -a 84000000 -e 84000000
-T firmware -d pbl.lzma patched_pbl.uimage
The resulting patched_pbl.uimage should have the sha256sum
b90d7fa2dcc6814180d3943530d8d6b0d6a03636113c94e99af34f196d3cf2ce
8. Reassemble the complete bootloader
$ dd if=patched_pbl.uimage of=aligned_pbl.uimage bs=143360 count=1
conv=sync
$ cat spl.bin > patched_uboot.bin
$ cat aligned_pbl.uimage >> patched_uboot.bin
$ cat ubnt.uimage >> patched_uboot.bin
The resulting patched_uboot.bin should have the sha256sum
3e1186f33b88a525687285c2a8b22e8786787b31d4648b8eee66c672222aa76b
9. Transfer your patched bootloader to the device. Also install the
kmod-mtd-rw package using opkg and load it.
$ insmod mtd-rw.ko i_want_a_brick=1
Write the patched bootloader to mtd0
$ mtd write patched_uboot.bin u-boot
10. Erase the kernel1 partition, as the bootloader might otherwise
decide to boot from there.
$ mtd erase kernel1
11. Transfer the OpenWrt sysupgrade image to the device and install
using sysupgrade.

A few devices in ath79 and ramips use mtd-concat to concatenate
individual partitions into a bigger "firmware" or "ubi" partition.
However, the original partitions are still present and visible,
and one can write to them directly although this might break the
actual virtual, concatenated partition.
As we cannot do much about the former, let's at least choose more
descriptive names than just "firmwareX" in order to indicate the
concatenation to the user. He might be less tempted into overwriting
a "fwconcat1" than a "firmware1", which might be perceived as an
alternate firmware for dual boot etc.
This applies the new naming consistently for all relevant devices,
i.e. fwconcatX for virtual "firmware" members and ubiconcatX for
"ubi" members.
While at it, use DT labels and label property consistently, and
also use consistent zero-based indexing.

- 2 external antennas (2.4 GHz)
- 9 LEDs, 1 button (power, wps, wifi2g, wifi5g, 5 LAN/WAN)
- USB 2 port (GPIO controlled power)
**MAC addresses:**
MAC Addresses are labeled as WAN and WLAN
U-boot environment has the the vendor MAC address for ethernet
MAC addresses in "factory" are part of wifi calibration data
eth0.2 WAN *:13:e7 u-boot-env wanaddr
eth0.1 ---- *:13:e8 u-boot-env wanaddr + 1
phy0 WLAN *:14:b8 factory 0x8004
phy1 ---- *:14:bc factory 0x4
**Installation:**
Method 1: Firmware upgrade page
OEM webpage at 192.168.0.1
username and password "admin"
Navigate to Network Setting --> Tools --> Firmware
Click Browse and select the factory.dlf image
Click Continue to confirm and wait 6 minutes or more...
Method 2: Serial console to load TFTP image:
(see TFTP recovery)
**Return to OEM:**
Unlike most Engenius boards, this does not have a 'failsafe' image
the only way to return to OEM is serial access to uboot
Unlike most Engenius boards, public images are not available...
so the only way to return to OEM is to have a copy
of the MTD partition "firmware" BEFORE flashing openwrt.
**TFTP recovery:**
Unlike most Engenius boards, TFTP is reliable here
however it requires serial console access
(soldering pins to the UART pinouts)
build your own image...
with 'ramdisk' selected under 'Target Images'
rename initramfs-kernel.bin to 'uImageESR-600H'
make the file available on a TFTP server at 192.168.99.8
interrupt boot by holding or pressing '4' in serial console
as soon as board is powered on
`tftpboot 0x81000000`
`bootm 0x81000000`
perform a sysupgrade
**Format of OEM firmware image:**
This Engenius board uses the Senao proprietary header
with a unique Product ID. The header for factory.bin is
generated by the mksenaofw program included in openwrt.
.dlf file extension is also required for OEM software to accept it
**Note on using OKLI:**
the kernel is now too large for the bootloader to handle
so OKLI is used via the `kernel-loader` image command
recently in master several other ramips boards have the same problem
'Kernel panic - not syncing: Failed to find ralink,rt3883-sysc node'

mt7621, mt7628an and rt5350 have USB controllers (ehci/ohci or xhci)
enabled by default. Thus, this patch drops redundant status=okay
statements in derived device DTS files.
While at it, also drop an explicit status=okay in mt7621.dtsi, as
this is default.
Note:
For rt5350, about 50 % of the devices enabled ehci/ohci in the DTS
files, and there is actually no device actively disabling it.
It looks like only a few people are aware that the controllers are
enabled by default here.

At the moment, ehci/ohci is enabled in mt7628an SoC DTSI, then
disabled in the TP-Link-specific DTSI files, and finally enabled
again in the DTS files of the devices needing it.
This on-off-on scheme is hard to grasp on a quick look. Thus, this
patch drops the status in the TP-Link-specific DTSI files, having
the TP-Link devices treated like the rest of mt7628an DTSes, i.e.
ehci/ohci is enabled by default and needs to be disabled explicitly
where needed.
