[Commotion-discuss] Some pre-experimentation mesh hardware inquiries

[Ben West]

I don't have any current versions of the 'minimal' ath5k-based Commotion
images, besides those listed below:

http://info.gowasabi.net/commotion-openwrt/openwrt/bin/atheros-ar2315-minimal/
Circa OpenWRT r31693, from Summer last year

http://info.gowasabi.net/commotion-openwrt-new/openwrt/bin/atheros-ar2315-minimal/
Like above, but with a newer kernel and compat-wireless library backported

All of these imageshould have the root pwd pre-set to r0ot56c0MM0t10N .

The only image I tested successfully were the older of the two version
listed above, on a FONera 2100.  Still, I have posted the config file I
used to build both versions, so that you can try building your own.

http://info.gowasabi.net/commotion-openwrt/openwrt/atheros-ar2315.minimal.config
http://info.gowasabi.net/commotion-openwrt-new/openwrt/atheros-ar2315.minimal.config

Please note the ath5k (aka atheros) images will not run on a WRT54G
(brcm47xx-based) or on the TP-Link (ath9k-based).

It should be straightforward (although tedious) to prune down the current
package set for DR1 Commotion to get a ~4MB sized image in squashfs.
Although, you would likely have to axe potentially useful features, e.g.
IPV6 support or Luci web UI.

Also, do be mindful of the RAM limitation for older devices like a WRT54G,
which has only 16MB of memory.  The recent incorporation of the zram
package into OpenWRT trunk may allow operation on such RAM-bound devices,
but to date I have *not* been able to run the v3.x kernel reliably on these
units.  And the OpenWRT dev team also doesn't expect it to, unfortunately.
