Permission denied

If you try to connect to a mote and receive a permission error, you may need to add yourself to the dialout group. The error may look something like the following:

/home/user/contiki/tools/sky/serialdump-linux -b115200 /dev/ttyUSB0
connecting to /dev/ttyUSB0 (115200)
/dev/ttyUSB0: Permission denied
make: *** [login] Error 255

To resolve the issue, simply use the following command:

sudo adduser <username> dialout

If you are getting an error /dev/ttyUSB0 Can't open port Error 1 followed by errors in the make file

Trying the following command which should give the desired output make TARGET=sky sky-motelist (sky can be replaced by the mote which is being used e.g z1)

The desired output ../../tools/sky/motelist-linux Reference Device Description

---

---------------- ---------------------------------------------

M4A7J5HF /dev/ttyUSB0 Moteiv tmote sky

This means it is a common serial port connection problem with Ubuntu 12.04 LTS.

sudo apt-get remove modemmanager

sudo adduser $USER dialout (or) sudo usermod -a -G dialout $USER // adds the user to the dialout // replace $USER by the username sudo reboot id -Gn And check now if the device is attached to the dialout user group.

ls -l /dev/ttyUSB0 crw-rw---- 1 root dialout 188, 0 Mar 5 19:58 /dev/ttyUSB0

There is no need to mess with dev rules or u permissions

Issue with make login

If you are trying to execute the serial-dump application (contiki/tools/sky/serialdump-linux) and see the message: "No such file or directory" or "Command not found", it means that you are running in a 64-bit operating system that does not have proper 32-bit libraries installed. Since serialdump-linux is a pre-compiled 32-bit tool you need to execute the following command to install the necessary libraries:

sudo apt-get install ia32-libs

If the above doesnot work

Then, try few commands like:

 ldd serialdump-linux

The output look similar to the following:

 ldd serialdump-linux
       linux-gate.so.1 =>  (0xf772d000)
       libc.so.6 => /lib32/libc.so.6 (0xf75b4000)
       /lib/ld-linux.so.2 (0xf772e000)

Then it means that you have to install 32-bit packages. Remember to add i386 architecture or you won't be able to install 32-bit packages:

 sudo dpkg --add-architecture i386
 sudo apt-get update
 sudo apt-get install ia32-libs
