Hi everyone

i just got myself a TPLINK WR720N

This one :
http://www.tp-link.com/en/products/deta … =TL-WR720N

Looking up on openwrt wiki i found out that WR720N that is supported is completely different from that one :
http://wiki.openwrt.org/toh/tp-link/tl-wr720n 

I opened the case and plug in TTL RX/TX to check a bit what is on the inside :
Here is a photo :
WR720N Opened

Also check the boot log i got with on TTL : 

picocom -b 115200 /dev/ttyUSB0 
picocom v1.7

port is        : /dev/ttyUSB0
flowcontrol    : none
baudrate is    : 115200
parity is      : none
databits are   : 8
escape is      : C-a
local echo is  : no
noinit is      : no
noreset is     : no
nolock is      : no

receive_cmd is : rz -vv
imap is        : 
omap is        : 
emap is        : crcrlf,delbs,

Terminal ready

I've documented myself a bit and i found out that this router seems to look a lot like the WR740N V4.23 :
Check at the bottom of this page for pictures :
http://wiki.openwrt.org/toh/tp-link/tl-wr740n

Only it has 2 lan instead of 4 lan (and maybe some other stuff i'm sure).

This router is quite cheap and seems interesting to work on.

Any of you know if any firmware in the lot already work for it ? i wanted to try the WR720 provided in trunk but as i have only one unit i wanted to make sure. Any help will be much appreciated.

Thanks

According datasheet A3S28D40FTP - 128 Mbit RAM, 16 Mbytes. Unable to read label from spi flash smile

And yes, you CAN run OpenWrt on 16 Mbytes, with custom images,

Thanks for the feedback smile

I'll try a custom build but i'm quite sure for wifi captive portal (with coova-chilli) i'll get past the 2 mb flash.

Even with minimal custom build 2mb is too low..

Check spi flash part number, 2 mb too low for vxworks too.

The discussion might have continued from here.
