Peter Till answers the original question. The additional below adds to this answer by showing how to automate the build and load process. I use Debian. The original question states that Ubuntu is used, which is built on Debian.
A script to find and mount the micro:bit
When code is loaded to the micro:bit, the board is dismounted from the system. So each time you have new code to load, you have to remount the board.
I modified a script to find and mount the micro:bit.
#!/bin/bash
BASEPATH="/media/$(whoami)/"
MICRO="MICROBIT"
if [ $# -eq 0 ]
then
echo "no argument supplied, use 'mount' or 'unmount'"
exit 1
fi
if [ $1 == "--help" ]
then
echo "mounts or unmounts a BBC micro:bit"
echo "args: mount - mount the microbit, unmout - unmount the microbit"
fi
# how many MICRO found in udiksctl dump
RESULTS=$(udisksctl dump | grep IdLabel | grep -c -i $MICRO)
case "$RESULTS" in
0 ) echo "no $MICRO found in 'udkisksctl dump'"
exit 0
;;
1 ) DEVICELABEL=$(udisksctl dump | grep IdLabel | grep -i $MICRO | cut -d ":" -f 2 | sed 's/^[ \t]*//')
DEVICE=$(udisksctl dump | grep -i "IdLabel: \+$DEVICELABEL" -B 12 | grep " Device:" | cut -d ":" -f 2 | sed 's/^[ \t]*//')
DEVICEPATH="$BASEPATH""$DEVICELABEL"
echo "found one $MICRO, device: $DEVICE"
if [[ -z $(mount | grep "$DEVICE") ]]
then
echo "$DEVICELABEL was unmounted"
if [ $1 == "mount" ]
then
udisksctl mount -b "$DEVICE"
exit 0
fi
else
echo "$DEVICELABEL was mounted"
if [ $1 == "unmount" ]
then
udisksctl unmount -b "$DEVICE"
exit 0
fi
fi
;;
* ) echo "more than one $MICRO found"
;;
esac
echo "exiting without doing anything"
I alias this script to mm in my .bashrc file.
Automate mounting the micro:bit and flashing the python file
I use the inotifywait command to run mm and to then run uflash to load the .py file I am working on. Each time that the python file is saved, the aliased command mm is run followed by the uflash command.
while inotifywait -e modify <your_file>.py ; do mm && uflash <your_file>.py ; done
