This removes USB support from the compiled kernel. Because of this, the
kernel is just small enough for the TP-Link WDR4900 to boot the
resulting kernel.
This is necessary to support the WDR4900 in the upcoming 19.xx release.
In the long run, this should be fixed with a second stage bootloader, as
the vendor bootloader only loads the first 2684k bytes.

that the A7v5 responds on "11", while the C7v5 responds on

The Ubiquiti Network airCube ISP is a cube shaped 2.4 GHz with internal
2x2 MIMO antennas. It can be supplied via a USB connector or via PoE.
There are for 10/100 Mbps ports (1 * WAN + 3 * LAN). There is an
optional PoE passthrough from the first LAN port to the WAN port.
SoC: Qualcomm / Atheros QCA9533-BL3A
RAM: 64 MB DDR2
Flash: 16 MB SPI NOR
Ethernet: 4x 10/100 Mbps (1 WAN + 3 LAN)
LEDS: 1x via a SPI controller (not yet supported)
Buttons: 1x Reset
Serial: 1x (only RX and TX); 115200 baud, 8N1
Missing points:
- LED not yet supported
- Factory upgrade via web IF or TFTP recovery not yet supported
(Needs RSA signed images, for details see PR#1958)
The serial port is on a four pin connextor labeled J1 and located
between Ethernet and USB connector. The pinout is:
1. 3V3 (out)
2. Rx (in)
3. Tx (out)
4. GND
Upgrading via serial port / U-Boot:
- Connect the serial port via a level converter
- Power the system and stop U-Boot with pressing any key when `Hit any
key to stop autoboot` is displayed. Note: Pressing space multiple
times untill U-Boot reaches that location works well.
- Connect a PC with the IP 192.168.1.100 (or some other in that net)
running a TFTP-Server to one of the LAN ports. Copy the sysupgrade
image to the server.
- Set the U-Boot server IP with
setenv serverip 192.168.1.100
- Load the flash image to RAM with
tftpboot 0x81000000 sysupgrade.bin
- Erase the flash with

- Write the new flash content with

Flashing instructions using recovery method over TFTP
1. Unplug the ethernet cable from the router.
2. Using paper clip press and hold the router's reset button. Make sure
you can feel it depressed by the paper clip. Do not release the button
until step 4.
3. While keeping the reset button pressed in, plug the ethernet cable
back into the AP. Keep the reset button depressed until you see the
device's LEDs flashing in upgrade mode (alternating LED1/LED3 and
LED2/LED4), this may take up to 25 seconds.
4. You may release the reset button, now the device should be in TFTP
transfer mode.
5. Set a static IP on your Computer's NIC. A static IP of 192.168.1.25/24
should work.
6. Plug the PoE injector's LAN cable directly to your computer.
7. Start tftp client and issue following commands:

This is backport of the same functionality in ath79, from commit
d42a7c469 ("ath79: ubnt-m-xw: Fix factory image flashing using TFTP
recovery method")
Ubiquity allows flashing of unsigned factory images via TFTP recovery
method[1]. They claim in airOS v6.0.7 release changelog[2] following:
All future airOS versions will be signed in this way and not allow
unsigned firmware to be loaded except via TFTP.
U-boot bootloader on M-XW devices expects factory image revision
version in specific format. On airOS v6.1.7 with `U-Boot 1.1.4-s1039
(May 24 2017 - 15:58:18)` bootloader checks if the revision major(?)
number is actually a number, but in currently generated images there's
OpenWrt text and so the check fails:
Hit any key to stop autoboot: 0

Starting TFTP server...
Receiving file from 192.168.1.25:38438

By placing arbitrary correct number first in major version, we make the
bootloader happy and we can flash factory images over TFTP again:

TrimSlice uses U-Boot placed in NOR flash. Boots Linux from any media
connected to USB, SATA or SD card inserted in slot. Can also boot from
TFTP. To run OpenWrt one needs to update U-Boot to fairly recent version
(the versions, pre-dts/dts provided by CompuLab won't suffice):
1. Boot TrimSlice into Your current linux distro,
2. Download trimslice-spi.img from u-boot-trimslice subdir,
3. Install mtd-utils,
4. Run following commands:
flash_erase /dev/mtd0 0 256
nandwrite /dev/mtd0 trimslice-spi.img
5. Poweroff, insert SD card with OpenWrt, boot and enjoy.
If by some obstacle You can't follow those instructions, it is possible
to flash U-Boot using serial console.
1. Insert FAT or EXT2/EXT3 formatted SD card with trimslice-spi.img,
2. Interrupt boot process to enter U-Boot command line,
3. Run following commands:
${fs}load mmc 0 0x04080000 trimslice-spi.img
sf probe 0
sf erase 0 0x100000
sf write 0x04080000 0x0 ${filesize}
reset
4. Poweroff, insert SD card with OpenWrt, boot and enjoy.
If something went wrong with one of above steps, there is simple
recovery option:
1. Open the µSD slot security door to access the recovery-boot button,
2. Insert SD card with OpenWrt to the front slot while unpowered,
3. Power on the TrimSlice while pressing the recovery-boot button,
4. With this it should boot straigth to OpenWrt, from there download
trimslice-spi.img and execute following commands:
mtd erase /dev/mtd0
mtd write trimslice-spi.img /dev/mtd0
5. Reboot, now it should boot straigth to OpenWrt, without pressing the
recovery-boot button, with proper U-Boot flashed.
