* [components][clock_time] Refactor time subsystem around clock_time Introduce the clock_time core with clock source/event separation, high-resolution scheduling, and boot-time helpers, plus clock_timer adapters for timer peripherals. Remove legacy ktime/cputime/hwtimer implementations and migrate arch and BSP time paths to the new subsystem while keeping POSIX time integration functional. Update drivers, Kconfig/SConscript wiring, documentation, and tests; add clock_time overview docs and align naming to clock_boottime/clock_hrtimer/clock_timer. * [components][clock_time] Use BSP-provided clock timer frequency on riscv64 * [risc-v] Use runtime clock timer frequency for tick and delays * [bsp] Add clock timer frequency hooks for riscv64 boards * [bsp] Update Renesas RA driver doc clock_timer link * [bsp] Sync zynqmp-r5-axu4ev rtconfig after config refresh * [bsp][rk3500] Update rk3500 clock configuration * [bsp][hpmicro] Add rt_hw_us_delay hook and update board delays * [bsp][stm32l496-st-nucleo] enable clock_time for hwtimer sample in ci * [bsp][hpmicro] Fix rtconfig include scope for hpm6750evk Move rtconfig.h include outside the ENET_MULTIPLE_PORT guard for hpm6750evk and hpm6750evk2 so configuration macros are available regardless of ENET settings. * [bsp][raspi3] select clock time for systimer * [bsp][hpm5300evk] Trim trailing blank line * [bsp][hpm5301evklite] Trim trailing blank line * [bsp][hpm5e00evk] Trim trailing blank line * [bsp][hpm6200evk] Trim trailing blank line * [bsp][hpm6300evk] Trim trailing blank line * [bsp][hpm6750evk] Trim trailing blank line * [bsp][hpm6750evk2] Trim trailing blank line * [bsp][hpm6750evkmini] Trim trailing blank line * [bsp][hpm6800evk] Trim trailing blank line * [bsp][hpm6e00evk] Trim trailing blank line * [bsp][nxp] switch lpc178x to gcc and remove mcx timer source * [bsp][stm32] fix the CONFIG_RT_USING_CLOCK_TIME issue. * [docs][clock_time] add clock time documentation * [docs][clock_time] Update clock time subsystem documentation - Update device driver index to use correct page reference - Clarify upper layer responsibilities in architecture overview - Update README to describe POSIX/libc, Soft RTC, and device driver usage - Refine architecture diagram with improved layout and color scheme - Remove obsolete clock_timer.md file * [kernel][utest] Trim trailing space * [clock_time] Fix hrtimer wrap handling * [clock_time] fix the static rt_inline issue * [clock_time] fix the rt_clock_hrtimer_control result issue
OPENMV4-H7-PLUS 开发板的 BSP 说明
简介
本文档为 OPENMV官方H7-PLUS开发板的 BSP (板级支持包) 说明。
主要内容如下：
- 开发板资源介绍
- BSP 快速上手
- 进阶使用方法
通过阅读快速上手章节开发者可以快速地上手该 BSP，将 RT-Thread 运行在开发板上。在进阶使用指南章节，将会介绍更多高级功能，帮助开发者利用 RT-Thread 驱动更多板载资源。
开发板介绍
OPENMV4-H7-PLUS 是 OPENMV公司推出的一款针对 STM32H7系列设计的 Cortex-M7 开发板。
开发板外观如下图所示：
该开发板常用 板载资源 如下：
- MCU：STM32H743IIK6，主频 480MHz，2MB FLASH ，1M RAM , Core Mark Score: 2400
- 常用外设
- RGB：3个，LED_R （红色，PC0）, LED_G(绿色，PC1), LED_B（蓝色，PC2），
- SRAM: 32MB
- QSPI FLASH: 32MB
- 调试接口，标准 SWD
开发板更多详细信息请参考 OpenMV4 H7 Plus开发板介绍。
外设支持
本 BSP 目前对外设的支持情况如下：
| 片上外设 | 支持情况 | 备注 |
|---|---|---|
| GPIO | 支持 | |
| USART | 支持 | USART1(PB14 TX)(PB15 RX) |
| SDRAM | 支持 | IS42S32800 BANK1 |
| QSPI FLASH | 支持 | W25Q256JV |
| SDIO | 支持 | USD-1040310811 |
| USBCDC | 支持 | |
| RTC | 支持 | |
| CAMERA | 支持 | OV5640 |
| DCMI | 支持 | |
| I2C | 支持 | I2C1(PB8 SCL)(PB9 SDA); I2C2 (PB10 SCL)(PB11 SDA) |
使用说明
使用说明分为如下两个章节：
-
快速上手
本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
-
进阶使用
本章节是为需要在 RT-Thread 操作系统上使用更多开发板资源的开发者准备的。通过使用 ENV 工具对 BSP 进行配置，可以开启更多板载资源，实现更多高级功能。
快速上手
本 BSP 为开发者提供 MDK4、MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
请注意！！！
在执行编译工作前请先打开ENV执行以下指令（该指令用于拉取必要的HAL库及CMSIS库，否则无法通过编译）：
pkgs --update
硬件连接
使用数据线连接开发板到 PC，打开电源开关。
编译下载
双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
工程默认配置使用 ST-LINK 仿真器下载程序，在通过 ST-LINK 连接开发板的基础上，点击下载按钮即可下载程序到开发板
运行结果
下载程序成功之后，系统会自动运行，红色的 LED_R 以 500MS 周期闪烁。
串口通信需要使用USB转TTL连接USART1。在终端工具里打开相应的串口（115200-8-1-N）, 复位设备后，可以看到 RT-Thread 的输出信息:

- RT - Thread Operating System
/ | \ 4.0.2 build Oct 2 2019

msh >
注意：由于BSP默认开启USBCDC，与shell的交互需通过虚拟串口。
进阶使用
此 BSP 默认开启了 GPIO 、 USART1、QSPI FLASH、USBCDC和CAMERA的功能，如果需使用更多高级功能，需要利用 ENV 工具对BSP 进行配置，步骤如下：
- 在 bsp 下打开 env 工具。
- 输入
menuconfig命令配置工程，配置好之后保存退出。 - 输入
pkgs --update命令更新软件包。 - 输入
scons --target=mdk4/mdk5/iar命令重新生成工程。
本章节更多详细的介绍请参考 STM32 系列 BSP 外设驱动使用教程。
注意事项
- 开机时如果不能打印 RT-Thread 版本信息，请重新选择 PC 端串口调试软件的串口号或将 BSP 中串口的 GPIO 速率调低
