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 the dialout 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 bootloader use

./neocon -t 30 /dev/ttyACM0

To quit neocon type:

~.

An alternative to NeoCon is picocom.
