hello, iirc tp-link mr3220 has only 4 megs of flash so your only option
is to try squeezing
stuff with openwrt buildroot kit, building your own customized image..
but thats risky if you
go for kernel and package customizing, might leave you locked out
without a serial console..
i managed to put ipv6, pppoe and luci on a 4 mb tp-link wr740 (same as
wr741), a small router
of around 20-30 usd, and i also adapted a serial output from its board
to an external phone CA-42 clone (from Arkmicro)..
so maybe if you can afford it and also link the serial to it you can go
play with the buildroot :)

The performance requirements are very modest. Just need to read from
the device every second (roughly), accumulate some data, and be able
to
send it to to a fixed ip address on the internet (probably using
SOAP).
Oh, and I prefer to use Python rather than C/C++ (but can compromise
if
that's the only option).
I need it to be really really cheap (sub $50), so a commodity device
is
probably the best way to go.
Are there any openwrt platforms that would be suitable ??
I do have a TP-Link MR3220. It works great and I'm sure I could use
a
USB-to-Serial cable (but it's and added expense that's not really
warranted).
Ideally I'd like one ethernet port (10Mb is ok), one external serial
port (and one internal would be cool too for root console). An
internal
SD slot would also be cool for larger custom filesystems.
Also, I tried doing an "opkg install curl" and "opkg install python"
but
they wouldn't fit on the device. Does it not really have enough
space
for these apps, or is using opkg the wrong way to go about things ??
Maybe creating a new filesystem and flashing it is the way to go ??
I
don't really know as I'm very new to openwrt :)
Thanks for any advice/pointers.
Brendan.
