Troubleshoot Running Linux Commands on BeagleBone Black Hardware
You changed the root user password, and now the
system function does not work. The current bbb
object uses the old password. To regain control of the Command Window, press
Ctrl+C. Clear the bbb object and any other
object based on the old password. Create a new connection using
beaglebone with the arguments that specify the new password.
Use the system function again.
