The default management interface should be easy to find for users
doing "blind" installations without console access. There are
already multiple examples in the forum of advanced early adopters
having problems locating the management interface after installing
OpenWrt.
Requiring tagged VLAN configration to access the initial management
interface creates unnecessary hassle at best. Errors on the other
end are close to impossible to debug without console access, even
for advanced users. Less advanced users might have problems with
the concept of VLAN tagging.
Limiting management access to a single arbitrary port among up to
52 possible LAN ports makes this even more difficult, for no
reason at all. Users might have reasons to use a different port
for management. And they might even have difficulties using the
OpenWrt selected one. The port might be the wrong type for their
management link (e.g copper instead of fibre). Or they might
depend on PoE power from a device which they can't reconfigure.
User expectations will be based on
- OpenWrt defaults for other devices
- stock firmware default for the device in question
- common default behaviour of similar devices
All 3 cases point to a static IP address accessible on the native
VLAN of any LAN port. A switch does not have any WAN port. All
ports are LAN ports.
This changes the default network configuration in line with these
expectations.

This patch adds support for the Teltonika RUTX10.
This device is an industrial DIN-rail router with 4 ethernet ports,
2.4G/5G dualband WiFi, Bluetooth, a USB 2.0 port and two GPIOs.
The RUTX series devices are very similiar so common parts of the DTS
are kept in a DTSI file. They are based on the QCA AP-DK01.1-C1 dev
board.
See https://teltonika-networks.com/product/rutx10 for more info.

USB detection of the bluetooth interface is sometimes a bit flaky. When
not detected power cycle the device. When the bluetooth interface was
detected properly it can be used with bluez / bluetoothctl.
Flash instructions via stock web interface (sysupgrade based):
1. Set PC to fixed ip address 192.168.1.100
2. Push reset button and power on the device
3. Open u-boot HTTP recovery at http://192.168.1.1
4. Upload latest stock firmware and wait until the device is rebooted
5. Open stock web interface at http://192.168.1.1
6. Set some password so the web interface is happy
7. Go to firmware upgrade settings
8. Choose
openwrt-ipq40xx-generic-teltonika_rutx10-squashfs-nand-factory.ubi
9. Set 'Keep settings' to off
10. Click update, when warned that it is not a signed image proceed
Return to stock firmware:
1. Set PC to fixed ip address 192.168.1.100
2. Push reset button and power on the device
3. Open u-boot HTTP recovery at http://192.168.1.1
4. Upload latest stock firmware and wait until the device is rebooted
Note: The DTS expects OpenWrt to be running from the second rootfs
partition. u-boot on these devices hot-patches the DTS so running from the
first rootfs partition should also be possible. If you want to be save follow
the instructions above. u-boot HTTP recovery restores the device so that when
flashing OpenWrt from stock firmware it is flashed to the second rootfs
partition and the DTS matches.

The MR42 and MR52 are two similar IPQ806x based devices from the Cisco
Meraki "Cryptid" series.
MR42 main features:
- IPQ8068 1.4GHz
- 512MB RAM
- 128MB NAND
- 2x QCA9992 (2.4 & 5GHz)
- 1x QCA9889 (2.4 & 5GHz)
- 1x AR8033 PHY
- PoE/AC power
MR52 main features:
- IPQ8068 1.4GHz
- 512MB RAM
- 128MB NAND
- 2x QCA9994 (2.4 & 5GHz)
- 1x QCA9889 (2.4 & 5GHz)
- 2x AR8033 PHYs
- PoE/AC power
(MR42 Only) Installation via diagnostic mode:
If you can successfully complete step 1 then you can continue to install
via this method without having to open the device. Otherwise please use
the standard UART method. Please note that when booting via TFTP, some
Ethernet devices, in particular those on laptops, will not connect in
time, resulting in TFTP boot not succeeding. In this instance it is
advised to connect via a switch.
1. Hold down reset at power on and keep holding, after around 10 seconds
if the orange LED changes behaviour to begin flashing, proceed to
release reset, then press reset two times. Ensure that the LED has
turned blue. Note that flashing will occur on some devices, but it
will not be possible to change the LED colour using the reset button.
In this case it will still be possible to continue with this install
method.
2. Set your IP to 192.168.1.250. Set up a TFTP server serving
mr42_u-boot.mbn and
openwrt-ipq806x-generic-meraki_mr42-initramfs-fit-uImage.itb, obtained
from [1].
3. Use telnet and connect to 192.168.1.1. Run the following commands to
install u-boot. Note that all these commands are critical, an error
will likely render the device unusable.
Option 3.1:
If you are sure you have set up the TFTP server correctly you can
run this script on the device. This will download and flash the
u-boot image immediately:
`/etc/update_uboot.sh 192.168.1.250 mr42_u-boot.mbn`
Once completed successfully, power off the device.
Option 3.2:
If you are unsure the TFTP server is correctly set up you can
obtain the image and flash manually:
3.2.1. `cd /tmp`
3.2.2. `tftp-hpa 192.168.1.250 -m binary -c get mr42_u-boot.mbn`
3.2.3. Confirm file has downloaded correctly by comparing the
md5sum:
`md5sum mr42_u-boot.mbn`
3.2.4. The following are the required commands to write the image.
`echo 1 > /sys/devices/platform/msm_nand/boot_layout
mtd erase /dev/mtd1
nandwrite -pam /dev/mtd1 mr42_u-boot.mbn
echo 0 > /sys/devices/platform/msm_nand/boot_layout`
Important: You must observe the output of the `nandwrite`
command. Look for the following to verify writing is occurring:
`Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x20000
Writing data to block 2 at offset 0x40000`
If you do not see this then do not power off the device. Check
your previous commands and that mr42_u-boot.mbn was downloaded
correctly. Once you are sure the image has been written you
can proceed to power off the device.
4. Hold the reset button and power on the device. This will immediately
begin downloading the appropriate initramfs image and boot into it.
Note: If the device does not download the initramfs, this is likely
due to the interface not being brought up in time. Changing Ethernet
source to a router or switch will likely resolve this. You can also
try manually setting the link speed to 10Mb/s Half-Duplex.
5. Once a solid white LED is displayed on the device, continue to the
UART installation method, step 6.
Standard installation via UART - MR42 & MR52
1. Disassemble the device and connect a UART header. The header pinout
is as follows:
1 - 3.3v
2 - TXD
3 - RXD
4 - GND
Important: You should only connect TXD, RXD and GND. Connecting
3.3v may damage the device.
2. Set your IP to 192.168.1.250. Set up a TFTP server serving
openwrt-ipq806x-generic-meraki_(mr42|mr52)-initramfs-fit-uImage.itb.
Separately obtain the respective sysupgrade image.
3. Run the following commands, preferably from a Linux host. The
mentioned files, including ubootwrite.py and u-boot images, can be
obtained from [1].
`python ubootwrite.py --write=(mr42|mr52)_u-boot.bin`
The default for "--serial" option is /dev/ttyUSB0.
4. Power on the device. The ubootwrite script will upload the image to
the device and launch it. The second stage u-boot will in turn load
the initramfs image by TFTP, provided the TFTP server is running
correctly. This process will take about 13 minutes. Once a solid
white LED is displayed, the image has successfully finished
loading. Note: If the image does not load via TFTP, try again with
the Ethernet link to 10Mb/s Half-Duplex.
5. (MR42 only) Do not connect over the network. Instead connect over
the UART using minicom or similar tool. To replace u-boot with
the network enabled version, please run the following commands.
Note that in the provided initramfs images, the u-boot.mbn file
is located in /root:
If you have not used the provided initramfs, you must ensure you
are using an image with "boot_layout" ECC configuration enabled in
the Kernel. This will be version 5.10 or higher. If you do not do
this correctly the device will be bricked.
`insmod mtd-rw i_want_a_brick=1
mtd erase /dev/mtd8
nandwrite -pam /dev/mtd8 /root/mr42_u-boot.mbn`
After running nandwrite, ensure you observe the following output:
`Writing data to block 0 at offset 0x0
Writing data to block 1 at offset 0x20000
Writing data to block 2 at offset 0x40000`
6. (Optional) If you have no further use for the Meraki OS, you can
remove all other UBI volumes on ubi0 (mtd11), including diagnostic1,
part.old, storage and part.safe. You must not remove the ubi1 ART
partition (mtd12).
`for i in diagnostic1 part.old storage part.safe ; do
ubirmvol /dev/ubi0 -N $i
done`
7. Proceed to flash the sysupgrade image via luci, or else download or
scp the image to /tmp and use the sysupgrade command.

Currently nand_upgrade_tar() will pass the kernel length
to nand_upgrade_prepare_ubi() in all cases except for when
the kernel is to be installed in a separate partition as a
binary with the MTD tool.
While this is fine for almost all cases newer MikroTik NAND
devices like hAP ac3 require the kernel to be installed as a
UBIFS packed UBI volume in its own partition.
So, since we have a custom recipe to use ubiformat to flash
the kernel in its partition it makes no sense for sysupgrade
to also install the kernel as a UBI volume in the "ubi"
partition as it only wastes space and will never be used.
So, simply check whether CI_KERNPART is set to "none" and
if so unset the "has_kernel" variable which will in turn
prevent the kernel length from being passed on and then
the kernel UBI volume wont be created for no usefull purpose.
The ath79 MikroTik NAND target has been setting CI_KERNPART
to "none" for a while now altough that was not preventing
the kernel to be installed as UBI volume as well.

Newer NAND devices from MikroTik like the hAP ac3
require the kernel to be packed into UBIFS and then
ubinized.
So, since the ubinize-image.sh script can now ubinize
kernel only as well lets add a command for it.
This now allows calling ubinize-kernel in the kernel
packaging at then end.

Currently ubinize-image script always expects the
rootfs image to be passed and a volume for it created.

the "cpu" or "software" reset mode. These devices also need to provide a
custom reboot mode, by adding the reboot argument to the kernel command
line:
WDT reset mode | kernel reboot mode
----------------+---------------------------------------
soc | reboot=cold (default if not specified)
cpu | reboot=warm
software | reboot=software
Preferrably, these devices should use an alternative restart method like
gpio-restart to provide reliable restarts.
Note that watchdog restarts are not yet exposed, since the
_machine_restart override is still present.

Add patch submitted upstream to linux-watchdog and replace the MIPS
architecture symbols. Requires one extra patch for the DIV_ROUND_*
macros, which have moved to a different header since 5.10.
