os
– basic “operating system” services¶
The os
module contains functions for filesystem access and urandom
function.
Port specifics¶
The filesystem has /
as the root directory and the
available physical drives are accessible from here. They are currently:
/flash
– the internal flash filesystem
/sd
– the SD card (if it exists)
On boot up, the current directory is /flash
.
