The ``usb-cdc`` configuration uses the internal HSI48 oscillator as +the 48 MHz USB clock. The clock recovery system synchronizes HSI48 from USB +start of frame packets, so no external 48 MHz crystal is required. + +Configurations +============== + +Each configuration is maintained in a sub-directory and selected with:: + + tools/configure.sh nucleo-l073rz:<subdir> + +nsh: +---- +Configures the NuttShell (NSH) on USART2. + +usb-cdc: +-------- +Configures NSH on USART2 and exposes a separate USB CDC/ACM serial device on +the USB FS connector.
