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
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", 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
