Subject: ath79: Add support for OpenMesh OM5P-AN
Device specifications:
======================
* Qualcomm/Atheros AR9344 rev 2
* 560/450/225 MHz (CPU/DDR/AHB)
* 64 MB of RAM
* 16 MB of SPI NOR flash
- 2x 7 MB available; but one of the 7 MB regions is the recovery image
* 1T1R 2.4 GHz Wi-Fi
* 2T2R 5 GHz Wi-Fi
* 6x GPIO-LEDs (3x wifi, 2x ethernet, 1x power)
* 1x GPIO-button (reset)
* external h/w watchdog (enabled by default)
* TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX)
* TI tmp423 (package kmod-hwmon-tmp421) for temperature monitoring
* 2x ethernet
- eth0
+ AR8035 ethernet PHY
+ 10/100/1000 Mbps Ethernet
+ 802.3af POE
+ used as LAN interface
- eth1
+ 10/100 Mbps Ethernet
+ builtin switch port 1
+ 18-24V passive POE (mode B)
+ used as WAN interface
* 12-24V 1A DC
* internal antennas
Flashing instructions:
======================
Various methods can be used to install the actual image on the flash.
Two easy ones are:
ap51-flash
----------
The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.
initramfs from TFTP
-------------------
The serial console must be used to access the u-boot shell during bootup.
It can then be used to first boot up the initramfs image from a TFTP server
(here with the IP 192.168.1.21):
setenv serverip 192.168.1.21
setenv ipaddr 192.168.1.1
tftpboot 0c00000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr
The actual sysupgrade image can then be transferred (on the LAN port) to the
device via
scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/
On the device, the sysupgrade must then be started using
sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin
