Problem:
When I try to flash my brick it gets stuck in SAMBA (soft continuous beeps) mode. At first it freaked me out and I thought my brick was really now a 'brick' but Eclipse on my Windows 7 Pro workstation is able to detect the brick and flash it.

Any ideas why I am unable to flash in Ubuntu

Please try to execute nxjflash (the command line version of our flashing tool) on the command line. It might uncover additional error messages.
The device is connected via USB? The udev rules are in place?

Some additional comments about your setup:

My Enviroment Setup:
In /etc/bash.bashrc

JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk
export JAVA_HOME

PATH=$PATH:$JAVA_HOME/bin
export PATH

LEJOS_NXT_JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk
export LEJOS_NXT_JAVA_HOME

NXJ_HOME=/home/lejos_user/lejos_nxj
export NXJ_HOME

PATH=$NXJ_HOME/bin:$PATH
export PATH

CLASSPATH=/home/lejos_user/Documents/lejos_projects
export CLASSPATH

I believe JAVA_HOME is already set by ubuntu - you don't need to set it manually. You also don't need to add the JDK's bin directory to the path. AFAIK, that is default on ubuntu as well.
But what you certainly shouldn't do is setting the CLASSPATH variable.

Use this:

Code: Select all

export LEJOS_NXT_JAVA_HOME=/usr/lib/jvm/java-1.6.0-openjdk
export NXJ_HOME=/home/lejos_user/lejos_nxj
export PATH=$NXJ_HOME/bin:$PATH

my ~.profile
export NXJ_HOME=/home/lejos_user/lejos_nxj
export LEJOS_HOME=$NXJ_HOME
export PATH=$PATH:$NXJ_HOME/bin
export CLASSPATH=$CLASSPATH:.:$NXJ_HOME/lib/classes.jar:$NXJ_HOME/lib/pccomm.jar:$NXJ_HOME/lib/jtools.jar:$NXJ_HOME/lib/pctools.jar

Some of those settings are redundant, since they are already set in /etc/bash.bashrc.
Also, don't set the CLASSPATH variable. The paths in the variable are wrong (in recent versions of leJOS, the classes.jar has moved to lib/nxt and the other JAR files have moved to lib/pc) and you're mixing NXT-side and PC-side JAR files and putting them all into one classpath. BAD idea!

Just remove those lines from ~/.profile
