== Flashing OpenWRT ==

Other Meraki routers have port 9000 open for telnet console connections for two seconds during bootup, but these boards do not. The router's RedBoot tries to load a .elf file via tftp during bootup. This file could contain a different RedBoot with tcp console enabled, but unfortunately I ([[User:Juul|Juul]] ([[User talk:Juul|talk]])) have not been able to get the built-in RedBoot to accept any .elf files (even ones compiled from Merakis RedBoot source code, which they have released). The files are only ever partially retrieved with no useful errors given on client or server. 

This means that we have to use the 3.3v serial port on the routers to gain console access.

*[[User:Juul|Juul]] ([[User talk:Juul|talk]]) has written [https://github.com/sudomesh/merakiflasher a script to flash these routers using serial and ethernet].
:Now works reliably.

== Watchdog problems! ==

The hardware watchdog is enabled per default and reboots the board every 5 minutes. This is why it takes 20+ minutes and four reboots to flash the router.

OpenWRT and Linux's watchdog support for the AR2317 chipset apparently is not functioning per default in OpenWRT Attitude Adjustment (possibly not in any version). This means the router will still reboot every 5 minutes after you flash with OpenWRT.

The watchdog support is supposed to work like so:

*Kernel driver creates /dev/watchdog as interfaces between hardware watchdog and userland
*watchdog daemon which is part of busybox writes null characters to /dev/watchdog periodically

The kernel code to support the watchdog is in linux-3.3.8/drivers/watchdog/ar2315-wtd.c and the memory mapped register addresses should be the same for the AR2317 as for the AR2317. The code appears to be compiled into OpenWRT Attitude Adjustment. Perhaps it is not loading because it only activates for AR2315 hardware? or perhaps some flag needs to be set at compile time?

== Where projects are the units going to? ==

* Dana wants to [https://www.noisebridge.net/pipermail/noisebridge-discuss/2013-November/040757.html take 20 units] for a community project ''(I'm in possession of 14 units as of 2013.11.27. If any go unused I will return them for other uses. ~ dana)''
* Sudoroom is interested in [https://www.noisebridge.net/pipermail/noisebridge-discuss/2013-November/040764.html all the units] for their open mesh networking project.
*Dan would like at least 1 outdoor version and 5-10 boards to provide wifi in the Mission around Noisebridge. https://openwireless.org nodes
* Adrian wants several to [https://www.noisebridge.net/pipermail/noisebridge-discuss/2013-November/040755.html improve Atheros support] in FreeBSD
* Jof wants boards for [https://www.noisebridge.net/pipermail/noisebridge-discuss/2013-November/040756.html mesh testing]
* [[User:Thex|J.C.]] has 2 boards for testing.
* Sudomesh has moved the majority of these to a slightly less public location as per [https://www.noisebridge.net/pipermail/noisebridge-discuss/2013-November/040764.html email suggestion] and no objections after three days. Need to count them.
