Troubleshooting
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
Use the following command (replace <username> with your account):
sudo adduser <username> dialout
You will then have to re-login to or reboot your computer for the changes to take effect. You should now have read/write permissions to your USB serial devices. It is not necessary to remove any packages.
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 does not 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
