UniElec U7621-01 is a router platform board, the smaller model of
the U7621-06.
The device has the following specifications:
- MT7621AT (880 MHz)
- 256 of RAM (DDR3)
- 16 MB of FLASH (SPI NOR)
- 5x 1 Gbps Ethernet (MT7621 built-in switch)
- 1x 2.4Ghz MT7603E
- 1x 5Ghz MT7612
- 1x miniPCIe slots (PCIe bus only)
- 1x miniSIM slot
- 1x USB 2.0 (uses the usb 3.0 driver)
- 8x LEDs (1x GPIO-controlled)
- 1x reset button
- 1x UART header (4-pins)
- 1x GPIO header (30-pins)
- 1x DC jack for main power (12 V)
The following has been tested and is working:
- Ethernet switch
- 1x 2.4Ghz MT7603E (wifi)
- 1x 5Ghz MT7612 (wifi)
- miniPCIe slots (tested with Wi-Fi cards and LTE modem cards)
- miniSIM slot (works with normal size simcard)
- sysupgrade
- reset button
Installation:
This board has no locked down bootloader. The seller can be asked to
install openwrt v18.06, so upgrades are standard sysupgrade method.
Recovery:
This board contains a Chinese, closed-source bootloader called Breed
(Boot and Recovery Environment for Embedded Devices). Breed supports web
recovery and to enter it, you keep the reset button pressed for around
5 seconds during boot. Your machine will be assigned an IP through DHCP
and the router will use IP address 192.168.1.1. The recovery website is
in Chinese, but is easy to use. Click on the second item in the list to
access the recovery page, then the second item on the next page is where
you select the firmware. In order to start the recovery, you click the
button at the bottom.

Port device support for Meraki MR12 from the ar71xx target to ath79.
Specifications:
- SoC: AR7242-AH1A CPU
- RAM: 64MiB (NANYA NT5DS32M16DS-5T)
- NOR Flash: 16MiB (MXIC MX25L12845EMI-10G)
- Ethernet: 1 x PoE Gigabit Ethernet Port (SoC MAC + AR8021-BL1E PHY)
- Ethernet: 1 x 100Mbit port (SoC MAC+PHY)
- Wi-Fi: Atheros AR9283-AL1A (2T2R, 11n)
Installation:
1. Requires TFTP server at 192.168.1.101, w/ initramfs & sysupgrade .bins
2. Open shell case
3. Connect a USB->TTL cable to headers furthest from the RF shield
4. Power on the router; connect to U-boot over 115200-baud connection
5. Interrupt U-boot process to boot Openwrt by running:
setenv bootcmd bootm 0xbf0a0000; saveenv;
tftpboot 0c00000 <filename-of-initramfs-kernel>.bin;
bootm 0c00000;
6. Copy sysupgrade image to /tmp on MR12
7. sysupgrade /tmp/<filename-of-sysupgrade>.bin
Notes:
- kmod-owl-loader is still required to load the ART partition into the
driver.
- The manner of storing MAC addresses is updated from ar71xx; it is
at 0x66 of the 'config' partition, where it was discovered that the
OEM firmware stores it. This is set as read-only. If you are
migrating from ar71xx and used the method mentioned above to
upgrade, use kmod-mtd-rw or UCI to add the MAC back in. One more
method for doing this is described below.
- Migrating directly from ar71xx has not been thoroughly tested, but
one method has been used a couple of times with good success,
migrating 18.06.2 to a full image produced as of this commit. Please
note that these instructions are only for experienced users, and/or
those still able to open their device up to flash it via the serial
headers should anything go wrong.
1) Install kmod-mtd-rw and uboot-envtools
2) Run `insmod mtd-rw.ko i_want_a_brick=1`
3) Modify /etc/fw_env.config to point to the u-boot-env partition.
The file /etc/fw_env.config should contain:
# MTD device env offset env size sector size
/dev/mtd1 0x00000 0x10000 0x10000
See https://openwrt.org/docs/techref/bootloader/uboot.config
for more details.
4) Run `fw_printenv` to verify everything is correct, as per the
link above.
5) Run `fw_setenv bootcmd bootm 0xbf0a0000` to set a new boot address.
6) Manually modify /lib/upgrade/common.sh's get_image function:
Change ...
cat "$from" 2>/dev/null | $cmd
... into ...
(
dd if=/dev/zero bs=1 count=$((0x66)) ; # Pad the first 102 bytes
echo -ne '\x00\x18\x0a\x12\x34\x56' ; # Add in MAC address
dd if=/dev/zero bs=1 count=$((0x20000-0x66-0x6)) ; # Pad the rest
cat "$from" 2>/dev/null
) | $cmd
... which, during the upgrade process, will pad the image by
128K of zeroes-plus-MAC-address, in order for the ar71xx's
firmware partition -- which starts at 0xbf080000 -- to be
instead aligned with the ath79 firmware partition, which
starts 128K later at 0xbf0a0000.
7) Copy the sysupgrade image into /tmp, as above
8) Run `sysupgrade -F /tmp/<sysupgrade>.bin`, then wait
Again, this may BRICK YOUR DEVICE, so make *sure* to have your
serial cable handy.

The PCI device ID detected by the wifi drivers on devices using a fallback
SPROM is wrong. Currently the chipnum is used for this parameter.
Most SSB based Broadcom wifi chips are 2.4 and 5GHz capable. But on
devices without a physical SPROM, the only one way to detect if the device
suports both bands or only the 5GHz band, is by reading the device ID from
the fallback SPROM.
In some devices, this may lead to a non working wifi on a 5GHz-only card,
or in the best case a working 2.4GHz-only in a dual band wifi card.
The offset for the deviceid in SSB SPROMs is 0x0008, whereas in BCMA is
0x0060. This is true for any SPROM version.
Override the PCI device ID with the one defined at the fallback SPROM, to
detect the correct wifi card model and allow using the 5GHz band if
supported.
The patch has been tested with the following wifi radios:
BCM43222: b43: both 2.4/5GHz working

The thermal zones kernel documentation is misleading, we cannot use more

In the Buffalo Linkstation LS421DE board there is also a sensor at the
ethernet phy chip that can also be monitored. Very useful to stop the fan
when there are no hard drives in the bays.
(It might be also possible to add the CPU sensor, but it requires kernel
patching for registering the sensor via device tree, using the function:
devm_thermal_zone_of_sensor_register)

Append a device specific version trailer used by the stock
firmware upgrade application to validate firmwares.
The trailer contains a list of ZyXEL firmware version
numbers, which includes a four letter hardware identifier.
The stock web UI requires that the current hardware matches
one of the listed versions, and that the version number is
larger than a model specific minimum value. The minimum
version varies between V1.00 and V2.60 for the currently
known GS1900 models. The number is not used anywhere else
to our knowlege, and has no direct relation to the version
info in the u-image header. We can therefore use an
arbitrary value larger than V2.60.
The stock firmware upgrade application will only load and
flash the part of the file specified in the u-image header,
regardless of file size. It can therefore not be used to
flash images with an appended rootfs. There is therefore no
need to include the trailer in other images than the
initramfs. This prevents accidentally bricking by attempts
to flash other images from the stock web UI.
Stock images support all models in the series, listing
all of them in the version trailer. OpenWrt provide model
specific images. We therefore only list the single supported
hardware identifier for each image. This eliminates the risk
of flashing the wrong OpenWrt image from stock web UI.
OpenWrt can be installed from stock firmware in two steps:
1) flash OpenWrt initramfs image from stock web gui
2) boot OpenWrt and sysupgrade to a squasfs image
The OpenWrt squashfs image depends on a static partition
map in the DTS. It can only be installed to the "firmware"
partition. This partition is labeled "RUNTIME1" in u-boot
and in stock firmware, and is referred to as "image 0" in
the stock flash management tool. The OpenWrt initramfs
can be installed and run from either partitions. But if
you want to keep stock irmware in the spare system partition,
then you must make sure stock firmware is installed to the
"RUNTIME2" partition referred to as "image 1" in the stock
web UI. And the initial OpenWrt initramfs must be flashed
to "RUNTIME1"/"image 0".
The stock flash management application supports direct
selection of both which partition to flash and which
partition to boot next. This allows software controlled
"dual-boot" between OpenWrt and stock firmware, without
using console access to u-boot. u-boot use the "bootpartition"
variable stored in the second u-boot environment to select
which of the two system partitions to boot. This variable
is set by the stock flash management application, by direct
user input. It can also be set in OpenWrt using e.g
fw_setsys bootpartition 1
to select "RUNTIME2"/"image 1" as default, assuming a
stock firmware version is installed in that partition.
Signed-off-by: Bjørn Mork <bjorn@mork.no>
The stock firmware of the ZyXEL GS1900 series use a non-standard
u-image magic. This is not enforced by the stock u-boot, which is
why we could boot images with the default magic. The flash
management application of the stock firmware will however verify
the magic, and refuse any image with another value.
Convert to vendor-specific value to get flash management support
in stock firmware, including the ability to upgrade to OpenWrt
directly from stock web UI.

x86 uses append-metadata, but only for signing and not for the
metadata itself.
Since recently SUPPORTED_DEVICES was assigned with a global value
and is not empty anymore, append-metadata will now actually put
metadata into x86 images. This breaks sysupgrade on x86.
To fix it for the moment, let's just empty SUPPORTED_DEVICES for
this target again.
In the long term, one should either not add metadata to the images
if it is not desired, and/or remove the unintended fwtool check.

FCC ID: A8J-EAP1200H
Engenius EAP1200H is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+
**Specification:**
- QCA9557 SOC
- QCA9882 WLAN PCI card, 5 GHz, 2x2, 26dBm
- AR8035-A PHY RGMII GbE with PoE+ IN
- 40 MHz clock
- 16 MB FLASH MX25L12845EMI-10G
- 2x 64 MB RAM NT5TU32M16FG
- UART at J10 populated
- 4 internal antenna plates (5 dbi, omni-directional)
- 5 LEDs, 1 button (power, eth0, 2G, 5G, WPS) (reset)
**MAC addresses:**
MAC addresses are labeled as ETH, 2.4G, and 5GHz
Only one Vendor MAC address in flash
eth0 ETH *:a2 art 0x0
phy1 2.4G *:a3 ---
phy0 5GHz *:a4 ---
**Serial Access:**
the RX line on the board for UART is shorted to ground by resistor R176
therefore it must be removed to use the console
but it is not necessary to remove to view boot log
optionally, R175 can be replaced with a solder bridge short
the resistors R175 and R176 are next to the UART RX pin at J10
**Installation:**
2 ways to flash factory.bin from OEM:
Method 1: Firmware upgrade page:
OEM webpage at 192.168.1.1
username and password "admin"
Navigate to "Firmware Upgrade" page from left pane
Click Browse and select the factory.bin image
Upload and verify checksum
Click Continue to confirm and wait 3 minutes
Method 2: Serial to load Failsafe webpage:
After connecting to serial console and rebooting...
Interrupt uboot with any key pressed rapidly
execute `run failsafe_boot` OR `bootm 0x9fd70000`
wait a minute
connect to ethernet and navigate to
"192.168.1.1/index.htm"
Select the factory.bin image and upload
wait about 3 minutes
**Return to OEM:**
If you have a serial cable, see Serial Failsafe instructions
otherwise, uboot-env can be used to make uboot load the failsafe image
*DISCLAIMER*
The Failsafe image is unique to Engenius boards.
If the failsafe image is missing or damaged this will brick the device
DO NOT downgrade to ar71xx this way, it can cause kernel loop or halt
ssh into openwrt and run
`fw_setenv rootfs_checksum 0`
reboot, wait 3 minutes
connect to ethernet and navigate to 192.168.1.1/index.htm
select OEM firmware image from Engenius and click upgrade
**TFTP recovery:**
Requires serial console, reset button does nothing
rename initramfs to 'vmlinux-art-ramdisk'
make available on TFTP server at 192.168.1.101
power board, interrupt boot
execute tftpboot and bootm 0x81000000
NOTE: TFTP is not reliable due to bugged bootloader
set MTU to 600 and try many times
**Format of OEM firmware image:**
The OEM software of EAP1200H is a heavily modified version
of Openwrt Kamikaze. One of the many modifications
is to the sysupgrade program. Image verification is performed
simply by the successful ungzip and untar of the supplied file
and name check and header verification of the resulting contents.
To form a factory.bin that is accepted by OEM Openwrt build,
the kernel and rootfs must have specific names...
openwrt-ar71xx-generic-eap1200h-uImage-lzma.bin
openwrt-ar71xx-generic-eap1200h-root.squashfs
and begin with the respective headers (uImage, squashfs).
Then the files must be tarballed and gzipped.
The resulting binary is actually a tar.gz file in disguise.
This can be verified by using binwalk on the OEM firmware images,
ungzipping then untaring.
Newer EnGenius software requires more checks but their script
includes a way to skip them, otherwise the tar must include
a text file with the version and md5sums in a deprecated format.
The OEM upgrade script is at /etc/fwupgrade.sh.
OKLI kernel loader is required because the OEM software
expects the kernel to be no greater than 1536k
and the factory.bin upgrade procedure would otherwise
overwrite part of the kernel when writing rootfs.
Note on PLL-data cells:
The default PLL register values will not work
because of the external AR8035 switch between
the SOC and the ethernet port.
For QCA955x series, the PLL registers for eth0 and eth1
can be see in the DTSI as 0x28 and 0x48 respectively.
Therefore the PLL registers can be read from uboot
for each link speed after attempting tftpboot
or another network action using that link speed
with `md 0x18050028 1` and `md 0x18050048 1`.
The clock delay required for RGMII can be applied
at the PHY side, using the at803x driver `phy-mode`.
Therefore the PLL registers for GMAC0
do not need the bits for delay on the MAC side.
This is possible due to fixes in at803x driver
since Linux 5.1 and 5.3
