Beside one exception, no one took care of these two remaining boards
still using the legacy image build code during the last two years.
Since OpenWrt 14.07 the ALLNET ALL0239-3G image building is broken.
The Sitecom WL-341 v3 image build code looks pretty hackish and broken.
It's questionable if the legacy image works as all.

Flashing requirements:
- needs a tftp server at 192.168.1.10/serverip.
- special 8P8C(aka RJ45)<->D-SUB9 Console Cable
("Cisco Console Cable"). Note: Both WNDAP6x0 have
a MAX3232 transceivers, hence no need for any separate
CMOS/TTL level shifters.
External Antenna:
The antennae mux is controlled by GPIO 11 and GPIO14. Valid Configurations:
= Config# = | = GPIO 11 = | = GPIO 14 = | ===== Description =====
1. | 1 / High | 0 / Low | Use the internal antennae (default)
2. | 0 / Low | 1 / High | Use the external antennae
The external antennaes are only meant for the 2.4 GHz band.
One-way Flashing instructions via u-boot:
0. connect the serial cable to the RJ45 Console Port
Note: This requires a poper RS232 and not a TTL/USB adaptor.
1. power up the AP and interrupt the u-boot process at
'Hit any key to stop autoboot'
2. setup serverip and ipaddr env settings
Enter the following commands into the u-boot shell
# setenv ipaddr 192.168.1.1
# setenv serverip 192.168.1.10
3. download the factory.img image to the AP
Enter the following commands into the u-boot shell
# tftp ${kernel_addr_r} openwrt-apm821xx-nand-netgear_wndap660-squashfs-factory.img
4. verfiy image integrity
Enter the following commands into the u-boot shell
# crc32 $fileaddr $filesize
If the calculated crc32 checksum does not match, go back to step 3.
5. flash the image
Enter the following commands into the u-boot shell
# nand erase 0x110000 0x1bd0000
# nand write ${kernel_addr_r} 0x110000 ${filesize}
6. setup uboot environment
Enter the following commands into the u-boot shell
# setenv bootargs
# setenv fileaddr
# setenv filesize
# setenv addroot 'setenv bootargs ${bootargs} root=/dev/ubiblock0_0'
# setenv owrt_boot 'nboot ${kernel_addr_r} nand0 0x110000; run addroot; run addtty; bootm ${kernel_addr_r}'
# setenv bootcmd 'run owrt_boot'
# saveenv
7. boot
# run bootcmd
Booting initramfs instructions via u-boot:
Follow steps 0 - 2 from above.
3. boot initramfs
Enter the following commands into the u-boot shell
# tftp ${kernel_addr_r} openwrt-apm821xx-nand-netgear_wndap660-initramfs-kernel.bin
# run addtty
# bootm ${kernel_addr_r}

Adds support for the Turris Omnia and builds an eMMC sysupgrade image in
the same format as the SolidRun ClearFog.
An initramfs image in the simple yet Omnia-specific 'medkit' image format
is also built in order to ease the initial flashing process.
Notable hardware support omissions are support for switching between SFP
cage and copper PHY, and RGB LED control.
Due to a current limitation of DSA, only 1/2 CPU switch uplinks are used.
Specifications:
- Marvell Armada 385 1.6GHz dual-core ARMv7 CPU
- 1GB DDR3 RAM
- 8GB eMMC Flash
- 5x Gigabit LAN via Marvell 88E6176 Switch (2x RGMII CPU ports)
- 1x switchable RJ45 (88E1514 PHY) / SFP SGMII WAN
- 2x USB 3.0
- 12x dimmable RGB LEDs controlled by independent MCU
- 3x Mini PCIe slots
- Optional Compex WLE200N2 Mini PCIe AR9287 2x2 802.11b/g/n (2.4GHz)
- Optional Compex WLE900VX Mini PCIe QCA9880 3x3 802.11ac (2.4 / 5GHz)
- Optional Quectel EC20 Mini PCIe LTE modem
Flash instructions:
If the U-Boot environment has been modified previously (likely manually via
serial console), first use serial to reset the default environment.
=> env default -a
=> saveenv
Method 1 - USB 'medkit' image w/o serial
- Copy openwrt-mvebu-turris-omnia-sysupgrade.img.gz and
omnia-medkit-openwrt-mvebu-turris-omnia-initramfs.tar.gz to the root of a
USB flash drive formatted with FAT32 / ext2/3/4 / btrfs / XFS.
Note that the medkit MUST be named omnia-medkit*.tar.gz
- Disconnect other USB devices from the Omnia and connect the flash drive
to either USB port.
- Power on the Omnia and hold down the rear reset button until 4 LEDs are
illuminated, then release.
- Wait approximately 2 minutes for the Turris Omnia to flash itself with
the temporary image, during which LEDs will change multiple times.
- Connect a computer to a LAN port of the Turris Omnia with a DHCP client
- (if necessary) ssh-keygen -R 192.168.1.1
- ssh root@192.168.1.1
$ mount /dev/sda1 /mnt
$ sysupgrade /mnt/openwrt-mvebu-turris-omnia-sysupgrade.img.gz
- Wait another minute for the final OpenWrt image to be flashed. The Turris
Omnia will reboot itself and you can remove the flash drive.
Method 2 - TFTP w/ serial
- Extract omnia-medkit-openwrt-mvebu-turris-omnia-initramfs.tar.gz and copy
dtb + zImage to your TFTP server (rename if desired)
- Connect Turris Omnia WAN port to DHCP-enabled network with TFTP server
- Connect serial console and interrupt U-Boot
=> dhcp
=> setenv serverip <tftp_server_ip_here>
=> tftpboot 0x01000000 zImage
=> tftpboot 0x02000000 dtb
=> bootz 0x01000000 - 0x02000000
- OpenWrt will now boot from ramdisk
- Download openwrt-mvebu-turris-omnia-sysupgrade.img.gz to /tmp/
$ sysupgrade /tmp/openwrt-mvebu-turris-omnia-sysupgrade.img.gz
- Wait another minute for the final OpenWrt image to be flashed. The Turris
Omnia will reboot itself.

This commit improves support for the Xiaomi Mi Router 3G originally
added in commit 6e283cdc0d
Improvements:
- Remove software watchdog as hardware watchdog now working as per
commit 3fbf3ab44f for all mt7621
devices.
- Reset button polarity corrected - length of press determines reboot
(short press) vs. reset to defaults (long press) behaviour.
- Enable GPIO amber switch port LEDs on board rear - lit indicates 1Gbit
link and blink on activity. Green LEDs driven directly by switch
indicating any link speed and tx activity.
- USB port power on/off GPIO exposed as 'usbpower'
- Add access to uboot environment settings for checking/setting uboot
boot order preference from user space.
Changes:
- Front LED indicator is physically made of independent Yellow/Amber,
Red & Blue LEDs combined via a plastic 'lightpipe' to a front panel
indicator, hence the colour behaviour is similar to an RGB LED. RGB
LEDs are not supported at this time because they produce colour results
that do not then match colour labels, e.g. enabling 'mir3g:red' and
'mir3g:blue' would result in a purple indicator and we have no such
label for purple.
The yellow, red & blue LEDs have been split out as individual yellow,
red & blue status LEDs, with yellow being the default status LED as
before and with red's WAN and blue's USB default associations removed.
- Swapped order of vlan interfaces (eth0.1 & eth0.2) to match stock vlan
layout. eth0.1 is LAN, eth0.2 is WAN
- Add 'lwlll' vlan layout to mt7530 switch driver to prevent packet
leakage between kernel switch init and uci swconfig
uboot behaviour & system 'recovery'
uboot expects to find bootable kernels at nand addresses 0x200000 &
0x600000 known by uboot as "system 1" and "system 2" respectively.
uboot chooses which system to hand control to based on 3 environment
variables: flag_last_success, flag_try_sys1_failed & flag_try_sys2_failed
last_success represents a preference for a particular system and is set
to 0 for system 1, set to 1 for system 2. last_success is considered *if*
and only if both try_sys'n'_failed flags are 0 (ie. unset) If *either*
failed flags are set then uboot will attempt to hand control to the
non failed system. If both failed flags are set then uboot will check
the uImage CRC of system 1 and hand control to it if ok. If the uImage
CRC of system is not ok, uboot will hand control to system 2
irrespective of system 2's uImage CRC.
NOTE: uboot only ever sets failed flags, it *never* clears them. uboot
sets a system's failed flag if that system's was selected for boot but
the uImage CRC is incorrect.
Fortunately with serial console access, uboot provides the ability to
boot an initramfs image transferred via tftp, similarly an image may
be flashed to nand however it will flash to *both* kernels so a backup
of stock kernel image is suggested. Note that the suggested install
procedure below set's system 1's failed flag (stock) thus uboot ignores
the last_success preference and boots LEDE located in system 2.
Considerable thought has gone into whether LEDE should replace both
kernels, only one (and which one) etc. LEDE kernels do not include a
minimal rootfs and thus unlike the stock kernel cannot include a
method of controlling uboot environment variables in the event of
rootfs mount failure. Similarly uboot fails to provide an external
mechanism for indicating boot system failure.
Installation - from stock.
Installation through telnet/ssh:
- copy lede-ramips-mt7621-mir3g-squashfs-kernel1.bin and
lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin to usb disk or wget it
from LEDE download site to /tmp
- switch to /extdisks/sda1/ (if copied to USB drive) or to /tmp if
wgetted from LEDE download site
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin rootfs0
- run: nvram set flag_try_sys1_failed=1
- run: nvram commit
- run: reboot
Recovery - to stock.
Assuming you used the above installation instructions you will have a
stock kernel image in system 1. If it can be booted then it may be used
to perform a stock firmware recovery, thus erasing LEDE completely. From
a 'working' LEDE state (even failsafe)
Failsafe only:
- run: mount_root
- run: sh /etc/uci-defaults/30_uboot-envtools
Then do the steps for 'All'
All:
- run: fw_setenv flag_try_sys2_failed 1
- run: reboot
The board will reboot into system 1 (stock basic kernel) and wait with
system red light slowly blinking for a FAT formatted usb stick with a
recovery image to be inserted. Press and hold the reset button for
around 1 second. Status LED will turn yellow during recovery and blue
when recovery complete.

IPQ806x AP148 and DB149 boards didn't have the UCI ubootenv
section initialized, so the usage of fw_printenv required manual
configuration. With this change, the "fw_printenv" and "fw_setenv"
command will automatically work on NOR and NAND based platforms.
