NeoCon
From Openmoko
neocon is a handy serial console utility (not only) for U-Boot.
neocon has a few graving advantages over some other terminal apps:
- You don't have to be
root
to access/dev/ttyACM0
with neocon. Being a member of thedialout
group should give you sufficient privileges. - by specifying a delay on keyboard input(as shown below), neocon will allow you to paste commands directly from clipboard without making U-Boot choke on it.
- neocon can be started without
/dev/ttyACM0
being available. It will automatically connect as soon as you start U-Boot on the Neo:
The main feature of neocon is actually that you can give it a list of devices and it will pick one that works, e.g.,
# neocon /dev/ttyUSB{0,1,2}
If you don't like the one it picked, you can switch to the next with
~n
This is useful for dynamically allocated devices, such as ttyUSBn
or ttyACMn
. You can of course also use them with other communication
programs - there's certainly no shortage of them - but then you have
to handle reconnects manually.
Installation
Download the source from http://svn.openmoko.org/developers/werner/neocon/ to a directory of your choice and build neocon by issuing
make
Usage
To connect to the U-Boot use
./neocon -t 30 /dev/ttyACM0
To quit neocon type:
~.
An alternative to NeoCon is picocom.
