I-O DATA WN-AX2033GR is roughly the same as I-O DATA
WN-AX1167GR2. The difference is Wi-Fi feature.
Specification
=============
- SoC: MediaTek MT7621A
- RAM: DDR3 128 MiB
- Flash Memory: NAND 128 MiB (Spansion S34ML01G200TF100)
- Wi-Fi: MediaTek MT7603E
- Wi-Fi: MediaTek MT7615
- Ethernet: 5x 10 Mbps / 100 Mbps / 1000 Mbps (1x WAN, 4x LAN)

==================
1. Open the router management page (192.168.0.1).
2. Update router firmware using "initramfs-kernel.bin".
3. After updating, run sysupgrade with "sysupgrade.bin".
Recovery instructions
=====================
WN-AX2033GR contains Zyxel Z-LOADER
1. Setup TFTP server (IP address: 10.10.10.3).
2. Put official firmware into TFTP server directory (distribution site:
https://www.iodata.jp/lib/software/w/2068.htm)
3. Connect WX-AX2033GR Ethernet port and computer that runs TFTP server.
4. Connect to serial console.
5. Interrupt booting by Esc key.

This reverts commit dcf3e63a35.
The kconfig update requires further testing and refinement until it can
remain in tree. Main problems are:
- Recursive deps are now fatal instead of a warning
- Previously legal syntax now leads to hard failures
- It fails all package builds since multiple days
The updated kconfig implementation needs to cope with the current status
quo in the various package feeds before we can reconsider it for master.
It is not desirable that single broken packages can hard-fail the entire
build pipeline.

kconfig-v5.6 disallowed a bool symbol to select another symbol that
'depends on m' (i.e. can be only 'm' on 'n'). It is, in fact, an unmet
dependency to have set to 'y'. However, openwrt depends on the previous
behavior, to be able to build a package that can be a module or built-in
depending on a bool config. This restores the previous behavior.

Cell C RTL30VW is a LTE router with tho gigabit ethernets and integrated
QMI mPCIE modem.
This is stripped version of ASKEY RTL0030VW.
Hardware:
Specification:
-CPU: IPQ4019
-RAM: 256MB
-Flash: NAND 128MB + NOR 16MB
-WiFi: Integrated bgn/ac
-LTE: mPCIe card (Modem chipset MDM9230)
-LAN: 2 Gigabit Ports
-USB: 2x USB2.0
-Serial console: RJ-45 115200 8n1
-Unsupported VoIP
Known issues:
None so far.
Instruction install:
There are two methods: Factory web-gui and serial + tftp.
Web-gui:
1. Apply factory image via stock web-gui.
Serial + initramfs:
1. Rename OpenWrt initramfs image to "image"
2. Connect serial console (115200,8n1)
3. Set IP to different than 192.168.1.11, but 24 bit mask, eg. 192.168.1.4.
4. U-Boot commands:
sf probe && sf read 0x80000000 0x180000 0x10000
setenv serverip 192.168.1.4
set fdt_high 0x85000000
tftpboot 0x84000000 image
bootm 0x84000000
5. Install sysupgrade image via "sysupgrade -n"
Back to stock:
All is needed is swap 0x4c byte in mtd8 from 0 to 1 or 1 to 0,
do firstboot and factory reset with OFW:
1. read mtd8:
dd if=/dev/mtd8 of=/tmp/mtd8
2. go to tmp:
cd /tmp/
3. write first part of partition:
dd if=mtd8 of=mtd8.new bs=1 count=76
4. check which layout uses bootloader:
cat /proc/mtd
5a. If first are kernel_1 and rootfs_1 write 0:
echo -n -e '\x00' >> mtd8.new
5b. If first are kernel and rootfs write 1:
echo -n -e '\x01' >> mtd8.new
6. fill with rest of data:
dd if=mtd8 bs=1 skip=77 >> mtd8.new
7. CHECK IF mtd8.new HAVE CHANGED ONLY ONE BYTE! e.g with:
hexdump mtd8.new
8. write new mtd8 to flash:
mtd write mtd8.new /dev/mtd8
9. do firstboot
10.reboot
11. Do back to factory defaults in OFW GUI.

With the "real HZ" debate out of the way, let's actually
use the apm821xx's default upstream config file at
arch/powerpc/configs/44x/bluestone_defconfig. From what
I can tell, it sets NO_HZ (well, this platform was for
NAS, so this is a bit unexpected) and remove any specific
HZ_$VALUE symbol.
Sadly, Daniel Engberg didn't run any before/after netperf
tests, because it would have been such a slam dunk across
the boards. In case of the apm821xx the tcp tx/rx
performance improved ~14% (from 600Mbps to 700Mps).
This now causes the emac to drop frames too, so let's see
if this is causes more problems or not.

"Whoop whoop, sound of da police"
Add an ingress capable traffic policer module configurable with tc.
From the man page:
The police action allows to limit bandwidth of traffic matched by the
filter it is attached to. Basically there are two different algorithms
available to measure the packet rate: The first one uses an internal
dual token bucket and is configured using the rate, burst, mtu,
peakrate, overhead and linklayer parameters. The second one uses an
in-kernel sampling mechanism. It can be fine-tuned using the estimator

instead of errors, by running make with WARN_RECURSIVE_DEP=1.

- Much more readable reverse dependencies separated in groups
- Improved recursive dependency report
- More readable .config files: add comments to signal end of menus
- More warnings for incorrect Config.in entries, such as a 'choice'
default not contained in the 'choice'
- Hability to properly display pseudographics with non-latin locales
- Recursive dependencies are now treated as errors - this should make

qconf (make xconfig), prepend its parent directory to the PATH, as it is

Currently, RTC_SUPPORT is defined as a tristate, with 'depends on m',
which is supposed to only let it be set to 'm' or 'n'. However,
scripts/target-metadata.pl will 'select' it, or setting it to 'y', which
defeats it's 'depends on m' restriction. The users of the symbol are
not expecting it to be necessarily 'm' either, so we can safely use it
as bool.
Newer versions of Linux 'conf' will issue a warning when it detects such
unmet dependencies, and will set it to 'n' instead of 'y', as the
current version does. In all cases, 'm' is never used.

IPv6 modules should all depend on @IPV6, to avoid circular dependencies
problems, especially if they select a module that depends on IPV6 as
well. In theory, if a package A depends on IPV6, any package doing
'select A' (DEPENDS+= A) should also depend on IPV6; otherwise selecting
A will fail. Sometimes the build system is forgiving this, but
eventually, and unexpectedly, it may blow up on some other commit.
Alternatively one can conditionally add IPv6 dependencies only if
CONFIG_IPV6 is selected: (DEPENDS+= +IPV6:package6).

- Output power 50mW (17dBm)
- 1x 10/100 Mbps LAN RJ45
- 128 MB RAM / 16 MB FLASH (w25q128)
- 3 LEDs (red/green/blue)
incorporated in
"color wheel reset switch"
- UART 115200 8N1
Flashing instructions:
The U-boot bootloader contains a recovery HTTP server
to upload the firmware. Push the reset button while powering the
device on and keep it pressed for ~10 seconds. The device's LEDs will
blink several times and the recovery page will be at
http://192.168.1.1; use it to upload the sysupgrade image.
Alternatively, the original firmware is based on OpenWrt so a
sysupgrade image can be installed via the stock web GUI. Settings from
the original firmware will be saved and restored on the new one, so a
factory reset will be needed. To do so, once the new firmware is flashed,
enter into failsafe mode by pressing the reset button several times during
the boot process, until it starts flashing. Once in failsafe mode, perform
a factory reset as usual.
LED-Info:
The LEDs on the Comfast stock fw have a very proprietary behaviour,
corresponding to the user selected working mode (AP, ROUTER or REPEATER).
In the first two cases, only blue is used for status and LAN signaling. When
using the latter, blue is always off (except for sysupgrade), either red
signals bad rssi on master-link, or green good. Since the default working
mode of OpenWrt resembles that of a router/AP, the default behavior is
implemented accordingly.
MAC addresses (art partition):
location address (example) use in vendor firmware
0x0 xx:xx:xx:xx:xc:f8 -> eth0
0x6 xx:xx:xx:xx:xc:fa -> wlan5g (+2)
0x1002 xx:xx:xx:xx:xc:f9 -> not used
0x5006 xx:xx:xx:xx:xc:fb -> not used

MAC addresses of the ethernet devices (eth0 & eth1) are randomly set at
boot time by the ag71xx driver, because it is currently not possible to
retrieve MAC addresses in ASCII format within the DTS file.
This commit works around this behaviour by setting the MAC addresses
during the preinit phase.
The same has been implemented recently for the Siemens WS-AP3610 in
d2b8ccb1c0 ("ath79: add support for Siemens WS-AP3610").
MAC assignment in vendor firmware is as follows:
use vendor address OpenWrt
2g wifi0 ethaddr -> wlan1
5g wifi1 ethaddr +1 -> wlan0
lan eth1 ethaddr +2 -> eth0
wan eth0 ethaddr +3 -> eth1
ethaddr is retrieved by $(mtd_get_mac_ascii u-boot-env ethaddr)
Note that both Wifi and ethernet indexing is swapped in OpenWrt
compared to vendor firmware.
