.. _cherry_shell_barebone_uart: Cherry Shell Barebone UART ==================================================== Overview -------- The Cherry Shell Barebone example project demonstrates the basic usage of shell in bare-metal mode. In this project, you need to connect via serial port, and the shell requires a login. The default password is 12345678. After entering the password and pressing Enter, you will enter the shell. You can use the "help" command to view the available commands and variables. Please refrain from using serial port assistants and consider downloading and using `MobaXterm `_ Board Setting ------------- No special settings Running the example ------------------- - After the project runs successfully, the serial terminal will output the following information: .. code-block:: console login as: cherry cherry@hpm5301evklite's password: other task interval 5S other task interval 5S other task interval 5S other task interval 5S other task interval 5S - If you manually enter the correct password "12345678" and press Enter, the terminal will output the following information: .. code-block:: console login as: cherry cherry@hpm5301evklite's password: other task interval 5S other task interval 5S other task interval 5S other task interval 5S other task interval 5S welcome to cherry shell cherry@hpm5301evklite:/$ - If you manually enter the command "help" and press Enter, the terminal will output the following information: .. code-block:: console cherry@hpm5301evklite:/$ help total function 6 test -> /bin toggle_led -> /bin write_led -> /bin exit -> /sbin help -> /sbin shsize -> /sbin total variable 2 $PATH r- 11 $ZERO r- 1 cherry@hpm5301evklite:/$ - If you manually enter the command "toggle_led" and press Enter, the LED will toggle. - If you manually enter the command "write_led 1" and press Enter, the LED will turn on. - If you manually enter the command "write_led 0" and press Enter, the LED will turn off.
