NUCLEO-U5A5ZJ-Q README
|

|
|
======================
|
||
|
|
|
||
|
|
This README file discusses the port of NuttX to the STMicroelectronics
|
||
|
|
NUCLEO-U5A5ZJ-Q board. That board features the STM32U5A5ZJT6Q MCU with 4MiB
|
||
|
|
of Flash and 2500KiB of SRAM.

2023-07-16: Initial port - works all ram memory and i2c(not extensively tested)
|

The i2c driver is based on stm32l4 one

|
Only the low speed external (LSE) 32.768kHz crystal (X2) is installed in
|
||
|
|
default configurations.

Virtual COM Port on USART1
|

--------------------------
|
||
|
|
|
||
|
|
Default board is configured to use USART1 as console. USART1 is connected
|
||
|
|
to the ST-LINKV3E Virtual COM port as well as made available on connector
|
||
|
|
CN10 (need some rework on PCB).

Information Common to All Configurations
|
||
|
|
----------------------------------------
|
||
|
|
There is only one configuration which can be selected as follow:
|
||
|
|
|
||
|
|
tools/configure.sh nucleo-u5a5zj-q:nsh
|
||
|
|
|
||
|
|
Before building, make sure the PATH environment variable includes the
|
||
|
|
correct path to the directory than holds your toolchain binaries.
|
||
|
|
|
||
|
|
And then build NuttX by simply typing the following. At the conclusion of
|
||
|
|
the make, the nuttx binary will reside in an ELF file called, simply, nuttx.
|
||
|
|
|
||
|
|
make menuconfig
|
||
|
|
make
|
||
|
|
|
||
|
|
The <subdir> that is provided above as an argument to the tools/configure.sh
|
||
|
|
must be is one of the following.
|
||
|
|
|
||
|
|
NOTES:
|
||
|
|
|
||
|
|
1. These configurations use the mconf-based configuration tool. To
|
||
|
|
change any of these configurations using that tool, you should:
|
||
|
|
|
||
|
|
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
|
||
|
|
see additional README.txt files in the NuttX tools repository.
|
||
|
|
|
||
|
|
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||
|
|
reconfiguration process.
|
||
|
|
|
||
|
|
2. All of these configurations are set up to build under Linux using the
|
||
|
|
"GNU Tools for ARM Embedded Processors" that is maintained by ARM
|
||
|
|
(unless stated otherwise in the description of the configuration).
