The XINU shell is designed as an interface for interacting with the operating system. The majority of the commands provide information about the current state of the system including its processes, memory, and hardware.


The XINU shell is equipped with some basic commands:

  • exit: quits the XINU shell
  • gpiostat: displays the current status of the GPIO pins
  • help: displays a list of commands in the XINU shell
  • kill PID: kills a process number PID
  • memstat: displays the current memory usage and prints the free list
  • memdump: dumps a region of memory
  • led DESCRIPTOR STATUS: turns an led on or off
  • ps: displays a table of running processes
  • reset: soft powercycles the backend
  • sleep DELAY: sleep for DELAY seconds
  • uartstat UARTNUM: displays statistics for uart UARTNUM
  • test: can be used for building test programs, all builds should simply return OK
  • testsuite: run a series of tests to see if the system is functioning properly
