Carambola1 (32MByte) the smallest possible webserver. (lighttpd + php5 working)

So here is how you connect to carambola / OpenWRT.

TO CLARIFY: THIS CARAMBOLA-WIKI-ENTRY SAYS:

„From factory Carambola is shipped with ttyS0 disabled. Or to be more precise it is in GPIO mode. Which is sometimes not what we want. It is very easy to change this.“

COM PORT SHOULD BE ENABLED PER DEFAULT! MY PROBLEM WAS I USED THE WRONG SERIAL CABLE!

DO NOT(!NOT! NOT NOT!) USE A NULLMODEM-CABLE + GENDER CHANGER IT WILL NOT WORK! JUST USE AN „EXTENSION“ CABLE WITH ALL WIRES STRAIGHT THROUGH. (NO CROSS OR TWIST)

(d.h. alle pole müssen einfach durchgeschliffen sein, NICHT GEKREUZT (KEIN NULLMODEM)!!)

„COM-KABEL-VERLÄNGERUNG MALE-FEMALE“ (NICHT NULLMODEM!!! NICHT GENDER CHANGER!)

and you can get it as cheap as 5€ / 5USD e.g. from here http://www.pololu.com/catalog/product/129

6 foot long serial extension cable with a DB9 male connector on one end and a DB9 female connector on the other end.

IF YOU USE A USB2SERIAL BE SHURE TO GET ONE WITH PL2303 CHIPSET (WORKS ALSO FOR LINUX+OSX).

e.g. the LogiLink AU0002b

now that you are wired lets start the software

Linux Debian Minicom settings:

you can also try picocom which might work even better…

apt-get update;
apt-get install minicom; # install minicom
sudo bash; # become root
minicom; # start minicom

# now hit Ctrl/Strg+A then O -> settings

if you press A or B it cycles through the possible baud rates available… for Carambola1 select 115200 (not one zero more or less)

if you get gobbeling / scrambled output it is probably because you did not set the baudrate correctly.

Also switch off Hardware and Software Flow Control (Press F -> No Press G -> No)

Hit Enter to save those settings.

Then select „Save setup as dfl“ and then exit.

Restart minicom via Ctrl/Strg+A -> X -> Leave Minicom? -> Yes

then start it again, it will now use the previously set settings.

and you should restart your caramobla and see it „boot up“ on your minicom screen 🙂 SUCCESS! 🙂

WINDOWS-PUTTY SETTINGS:

what you should get looks like this: (htop on carambola1… works! :-D)

 

if you hate bloatet-windows installations (it works well under parallels)

try this: http://pbxbook.com/other/mac-tty.html

and that
