* ! Behavior change !
Old behavior: If the Reset button is held down during power-on
do factory reset and try booting recovery from TFTP forever.
If valid recovery is received via TFTP, write it to flash and boot.
New behavior: If the Reset button is held down during power-on
do factory reset, then try TFTP *once*, then try booting on-flash
recovery, then keep trying via TFTP forever until a valid image is
received.
Only if there is no bootable recovery stored on flash, store the
downloaded recovery. Then boot it.
* Set loadaddr to 0x48000000 in order to allow booting images larger
than ~47MB (reported by Oskari Lemmelä). Setting loadaddr to
0x48000000 gives us 384MB on devices with 512MB RAM, which should be
more than enough as a maximum size for uImage.FIT to be loaded.

The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:
5g 2.4g increment
f4:XX:XX:a8:XX:66 f6:XX:XX:c8:XX:66 +0x20

x4:xx:xx:6a:xx:xx x6:xx:xx:4a:xx:xx -0x20
Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.
Flashing instruction:
The Dlink "Emergency Room" cannot be accessed through the reset

At the time of adding support the wireless config needs to be set up by
editing the wireless config file:
* Setting the country code is mandatory, otherwise the router loses
connectivity at the next reboot. This is mandatory and can be done
from luci. After setting the country code the router boots correctly.
A reset with the reset button will fix the issue and the user has to
reconfigure.
* This is minor since the 5g interface does not come up online although
it is not set as disabled. 2 options here:
1- Either run the "wifi" command. Can be added from LUCI in system -
startup - local startup and just add wifi above "exit 0".
2- Or add the serialize option in the wireless config file as shown
below. This one would work and bring both interfaces automatically
at every boot:
config wifi-device 'radio0'
option serialize '1'
config wifi-device 'radio1'
option serialize '1'

This device is very similar to the EA7300 v1/v2, EA7500 v2, and EA8100 v1.
Installation:
Upload the generated factory image through the factory web interface.
(following part taken from EA7300 v2 commit message:)
This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.
Reverting to factory firmware:
Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

The minew g1-c is a smart home gateway / BLE gateway.
A Nordic nRF52832 is available via USB UART (cp210x) to support BLE.
The LED ring is a ring of 24x ws2812b connect to a generic GPIO (unsupported).
There is a small LED which is only visible when the device is open which
will be used as LED until the ws2812b is supported.
The board has also a micro sdcard/tfcard slot (untested).
The Nordic nRF52832 exposes SWD over a 5pin header (GND, VCC, SWD, SWC, RST).
The vendor uses an older OpenWrt version, sysupgrade can be used via
serial or ssh.

Debricking (lite)
If you have a healthy bootloader, you can use recovery via TFTP using
programs like TinyPXE on Windows or dnsmasq on Linux. To switch the router
to TFTP recovery mode, hold down the reset button, connect the power
supply, and release the button after about 10 seconds. The router must be
connected directly to the PC via the LAN port.
Debricking
You will need a full dump of your flash, a CH341 programmer, and a clip
for in-circuit programming.
Install OpenWRT
1. Obtain SSH Access.
2. Create script (on router):
echo '#!/bin/sh' > /tmp/flash_fw.sh
echo >> /tmp/flash_fw.sh
echo '. /bin/boardupgrade.sh' >> /tmp/flash_fw.sh
echo >> /tmp/flash_fw.sh
echo 'board_prepare_upgrade' >> /tmp/flash_fw.sh
echo 'mtd erase rootfs_data' >> /tmp/flash_fw.sh
echo 'mtd write /tmp/openwrt.bin firmware' >> /tmp/flash_fw.sh
echo 'sleep 3' >> /tmp/flash_fw.sh
echo 'reboot' >> /tmp/flash_fw.sh
echo >> /tmp/flash_fw.sh
chmod +x /tmp/flash_fw.sh
3. Copy `openwrt-ath79-generic-xiaomi_aiot-ac2350-squashfs-sysupgrade.bin`
to the router (on PC):
scp openwrt-ath79-generic-xiaomi_aiot-ac2350-squashfs-sysupgrade.bin \
root@192.168.31.1:/tmp/openwrt.bin
4. Flash OpenWRT (on router):
/bin/ash /tmp/flash_fw.sh &
5. SSH connection will be interrupted - this is normal.

- Release reset button.
- The device starts a TFTP server at 192.168.1.20.
- Set a static IP on the computer (e.g., 192.168.1.21/24).

This partially reverts changes done in commit 72cc44958e ("treewide:
mark selected packages nonshared") as it removes the nonshared flag, but
keeps the PKG_RELEASE as the PKG_RELEASE bump while adding nonshared
flag was incorrect.
Unmark uci, ubus, libubox, lua, libnl-tiny and libjson-c as nonshared
packages as this fix attempt didn't worked out. Currently the
imagebuilder is broken again:
openwrt-imagebuilder-21.02.0-rc3-ipq40xx-generic.Linux-x86_64$ make image PROFILE=avm_fritzbox-7530 PACKAGES=luci-ssl-openssl
...
Collected errors:
* pkg_hash_check_unresolved: cannot find dependency libiwinfo20210430 for luci-mod-status
* pkg_hash_fetch_best_installation_candidate: Packages for luci-mod-status found, but incompatible with the architectures configured
* pkg_hash_check_unresolved: cannot find dependency libiwinfo20210430 for rpcd-mod-iwinfo
* pkg_hash_fetch_best_installation_candidate: Packages for rpcd-mod-iwinfo found, but incompatible with the architectures configured
* satisfy_dependencies_for: Cannot satisfy the following dependencies for luci-ssl-openssl:
* libiwinfo20210430
* opkg_install_cmd: Cannot install package luci-ssl-openssl.
Everything because iwinfo's ABI was changed two times since rc3 release:
+IWINFO_ABI_VERSION:=20210430
+IWINFO_ABI_VERSION:=20210420
Since iwinfo is marked as nonshared, it wasn't built by phase2 builders, but
luci-mod-status was already updated 2 times since rc3 and was thus rebuilt by
phase2 builders:
d1d452ed2fb3 luci-mod-status: don't set '-' hostname when creating static lease
95b3633055c1 luci-mod-status: switch to html table for wlan channel analysis
So now luci-mod-status depends on libiwinfo20210430 but only
libiwinfo20210106 can be downloaded. This is first part of the fix, in
the upcoming commit Jo is going to remove nonshared flag from iwinfo
package as well.

Analysis done by Denis Kalashnikov:
It seems that some ROS versions on some routerboard models have this bug:
after silence boot (no output to uart, no beeps) beeper clicks when wireless traffic is.
https://forum.mikrotik.com/viewtopic.php?f=3&t=92269https://forum.mikrotik.com/viewtopic.php?t=63399
From these links:
1)
Hello, I have RB951G-2HnD and I noticed strange thing
when I loaded the device with some wireless traffic it
produced strange sound - like hissing, fizzing etc.
2)
Same problem still on 6.33, with silent boot enabled
I hear buzzing noise on wireless load.
3)
The sound is fixed in v5.19, it was a bug that caused beeper to make clicks.
It also got fixed in RouterOS:
* What's new in 5.19 (2012-Jul-16 10:51):
fix ticking sound on RB411UAHL;
* What's new in 6.38.3 (2017-Feb-07 09:52):
rb3011 - fixed noise from buzzer after silent boot;
I've checked with an oscilloscope that:
* When on the ssr beeper pin is 0,
on the beeper itself is 1 (~5V),
and when on the ssr beeper pin is 1,
on the beeper is 0
The beeper doesn't consume power,
so 1 should be a default/idle value for the ssr beeper pin).
* When there is wireless traffic (ping packets)
in the background and the beeper clicks, I see
pulses on the beeper itself,
but no pulses on the ssr beeper pin (Q5 pin of 74hc595).
When I manually toggle the ssr beeper pin I see pulses on both.
So, it is likely that the phantom beeper clicks are caused by the EMI.
