* 2T2R 2.4 GHz
- QCA4019 hw1.0 (SoC)

* multi-color LED (controlled via red/green/blue GPIOs)
* 1x button (reset; kmod-input-gpio-keys compatible)
* external watchdog
- triggered GPIO
* 1x USB (xHCI)
* TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX)
* 2x gigabit ethernet
* powered only via POE
- 802.3af POE on Ethernet 1
- 18-24v passive POE (mode B) on Ethernet 2
The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the factory image to the u-boot when the device boots up.

# The U-Boot loader of the OpenMesh devices requires image sizes and |

# checksums to be provided in the U-Boot environment. |
||||||
|
# The OpenMesh devices come with 2 main partitions - while one is active |
||||||
|
# sysupgrade will flash the other. The boot order is changed to boot the |
||||||
|
# newly flashed partition. If the new partition can't be booted due to |
||||||
|
# upgrade failures the previously used partition is loaded. |

# detect to which flash region the new image is written to. |
||||||
|
# |
||||||
|
# 1. check what is the mtd index for the first flash region on this |
||||||
|
# device |
||||||
|
# 2. check if the target partition ("inactive") has the mtd index of |
||||||
|
# the first flash region |
||||||
|
# |
||||||
|
# - when it is: the new bootseq will be 1,2 and the first region is |
||||||
|
# modified |
||||||
|
# - when it isnt: bootseq will be 2,1 and the second region is |
||||||
|
# modified |
||||||
|
# |
||||||
|
# The detection has to be done via the hardcoded mtd partition because |
||||||
|
# the current boot might be done with the fallback region. Let us |
||||||
|
# assume that the current bootseq is 1,2. The bootloader detected that |
||||||
|
# the image in flash region 1 is corrupt and thus switches to flash |
||||||
|
# region 2. The bootseq in the u-boot-env is now still the same and |
||||||
|
# the sysupgrade code can now only rely on the actual mtd indexes and |
||||||
|
# not the bootseq variable to detect the currently booted flash |
||||||
|
# region/image. |
||||||
|
# |
||||||
|
# In the above example, an implementation which uses bootseq ("1,2") to |
||||||
|
# detect the currently booted image would assume that region 1 is booted |
||||||
|
# and then overwrite the variables for the wrong flash region (aka the |
||||||
|
# one which isn't modified). This could result in a device which doesn't |
||||||
|
# boot anymore to Linux until it was reflashed with ap51-flash. |
