System Clock
|
|
------------
|
|
|
|
Nucleo L4R5ZI System Clock could be driven by internal or external
|
|
oscillator, as well as main PLL clock. By default, the System clock is
|
|
driven by the PLL clock at 80MHz, driven by a 16MHz high speed
|
|
internal oscillator. The clock can be boosted to 120MHz if boost mode
|
|
is selected.
|
|
|
|
Serial Port
|
|
-----------
|
|
|
|
Nucleo L4R5ZI board has 5 U(S)ARTs. The Zephyr console output is
|
|
assigned to UART2. Default settings are 115200 8N1.
|
|
|
|
Network interface
|
|
-----------------
|
|
|
|
Ethernet over USB is configured as the default network interface (EEM)
|
|
|
|
Programming and Debugging
|
|
*************************
|
|
|
|
Currently, the usual way of programming and debugging does not
|
|
exist. This will hopefully be added to a future version of the SDK. In
|
|
the meantime, the `STM32 ST-LINK utility`_ program can be used by
|
|
connecting CN1 to your PC and selecting the zephyr.bin file to flash.
