|
|
STMicro NUCLEO-H743ZI2 development board featuring the STM32H743ZI
|
|
|
|
|
|
MCU. The STM32H743ZI is a 400MHz Cortex-M7 operation with 2MBytes Flash

Serial Console
|
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
|
|
Many options are available for a serial console via the Morpho connector.
|
|
|
|
|
|
Here two common serial console options are suggested:
|
|
|
|
|
|
|
|
|
|
|
|
1. Arduino Serial Shield.
|
|
|
|
|
|
|
|
|
|
|
|
If you are using a standard Arduino RS-232 shield with the serial
|
|
|
|
|
|
interface with RX on pin D0 and TX on pin D1 from USART6:

|
|
|
|
|
|
|
|
2. Nucleo Virtual Console.
|
|
|
|
|
|
|
|
|
|
|
|
The virtual console uses Serial Port 3 (USART3) with TX on PD8 and RX on
|
|
|
|
|
|
PD9.
|
|
|
|
|

|

|
|
|
SERIAL_TX PD8
|
|
|
|
|
|
----------------- ---
|
|
|
|
|
|
|
|
|
|
|
|
These signals are internally connected to the on board ST-Link.
|
|
|
|
|
|
|
|
|
|
|
|
The Nucleo virtual console is the default serial console in all
|
|
|
|
|
|
configurations unless otherwise stated in the description of the
|
|
|
|
|
|
configuration.

This configuration provides a basic NuttShell configuration (NSH)
|
|
|
|
|
|
for the Nucleo-H743ZI. The default console is the VCOM on USART3.

This configuration enables many Apache NuttX features. This is
|
2021-03-27 22:19:10 +01:00
|
|
|
|
mostly to help provide additional code coverage in CI, but also
|
|
|
|
|
|
allows for a users to see a wide range of features that are
|
|
|
|
|
|
supported by the OS.
|
|
|
|
|
|
Some highlights:
|
|
|
|
|
|
NSH:
|
|
|
|
|
|
