bsp/fm33lg026: 新增 FM33LG0xx BSP（基于官方 fm33lc026 移植） by WChengLei · Pull Request #11729 · RT-Thread/rt-thread

WChengLei · 2026-08-21T07:02:40Z

概述

新增 FM33LG0xx BSP（bsp/fm33lg026），并将厂商库改为通过 RT-Thread 软件包引入，不再内嵌于 BSP 仓库。

配套软件包：fm33lg0xx_fl_library（复旦微官方 FL_Library v2.3.5 原样封装，Mulan PSL v2）

包主体：https://github.com/WChengLei/fm33lg0xx_fl_library
索引 PR：[add] fm33lg0xx_fl_library: FM33LG0xx FL Library package packages#2030 （本 PR 依赖该索引先合并，否则 pkgs --update 无法拉取）

变更内容

BSP 本体（基于官方 fm33lc026 移植）

底层驱动替换为官方 FM33LG0XX_FL_Library v2.3.5（CMU 时钟、rtca/rtcb 拆分）
板级适配：64MHz PLL、32K RAM、uart0 console、LED PC1
修复官方 BSP 存量 bug：drv_gpio.c 补 INIT_BOARD_EXPORT；GET_PIN 宏步长 0x400→0x40
MDK5 工程（scons 生成），已验证 msh + GPIO 全链路跑通

软件包化（本次新增）

删除 BSP 内嵌厂商库（libraries/FM/ + libraries/FM33LG0xx_FL_Driver/），改由 fm33lg0xx_fl_library 软件包提供
SConstruct/board/SConscript 路径指向包内 CMSIS 布局；rtconfig.h 启用 PKG_USING_FM33LG0XX_FL_LIBRARY
启动文件、驱动库与包同源，避免 BSP 与厂商库版本不一致

review 反馈修复

drv_usart.c：移除 STM32 遗留的 stm32_dma_config 调用（FM33 未实现 DMA），RT_DEVICE_CTRL_CONFIG 返回 -RT_ENOSYS；RT_ASSERT(0) 补分号
board/Kconfig：UART0 默认开启、UART1/UART5 默认关闭（匹配板载调试串口）
uart_config.h：修正 UART5 配置字段（.InitTypeDef + .clockSrc）

为什么提交这份 PR

新增 FM33LG0xx BSP，并遵循维护者建议将厂商库独立为软件包，减小主仓库体积、便于厂商库独立升级。

请提供验证的 bsp 和 config

BSP: bsp/fm33lg026
编译验证：scons（gcc）与 MDK5 均编译通过
索引 PR：[add] fm33lg0xx_fl_library: FM33LG0xx FL Library package packages#2030 （本 PR 依赖该索引先合并，否则 pkgs --update 无法拉取）

后续维护

包主体仓库（WChengLei/fm33lg0xx_fl_library）为独立仓库
如需将软件包仓库迁移至 RT-Thread-packages 组织统一维护，愿意配合完成迁移
同步规划：FM33LC0xx 系列对应软件包（fm33lc0xx_fl_library）后续提交

- 底层驱动替换为官方 FM33LG0XX_FL_Library v2.3.5（CMU 时钟、rtca/rtcb 拆分） - 板级适配：64MHz PLL、32K RAM、uart0 console、LED PC1 - 修复官方 BSP 存量 bug：drv_gpio.c 补 INIT_BOARD_EXPORT；GET_PIN 宏步长 0x400→0x40 - MDK5 工程（scons 生成），已验证 msh + GPIO 全链路跑通"

可以的，我看现在bsp里面fm33系列的mcu只有一个lc0和lg0，其他的还需要我做什么吗？

Pull request overview

This PR adds a new bsp/fm33lg026 BSP for the Fudan Microelectronics FM33LG0xx series, ported from the existing FM33LC0xx BSP and switching the low-level driver library to the official FM33LG0XX_FL_Library v2.3.5.

本 PR 新增 bsp/fm33lg026 BSP，用于复旦微 FM33LG0xx 系列 MCU，基于现有 FM33LC0xx BSP 移植，并替换底层驱动为官方 FM33LG0XX_FL_Library v2.3.5。

Changes / 变更点：

Add FM33LG026 BSP build scaffolding (SCons/Kconfig/linker scripts) and basic board init (clock/heap/console).
新增 FM33LG026 BSP 的构建骨架（SCons/Kconfig/链接脚本）与基础板级初始化（时钟/堆/console）。
Add HAL driver layer stubs for RT-Thread devices (GPIO/UART/etc.) and configuration headers.
新增 RT-Thread 设备驱动适配层（GPIO/UART 等）及配置头文件。
Vendor in FM33LG0xx FL driver sources/headers and templates needed by the BSP.
引入 FM33LG0xx FL 驱动源码/头文件与 BSP 相关模板文件。

Review blockers found / 发现的阻塞问题：

uart_config.h uses non-existent struct fields (.Instance) and has preprocessor block mismatches → build break when enabling related UARTs.
uart_config.h 使用不存在的结构体字段（.Instance）且预处理块收尾不匹配 → 相关 UART 使能会直接编译失败。
drv_usart.c has a missing semicolon and references an undefined stm32_dma_config() under DMA → build break in current form.
drv_usart.c 存在缺少分号以及 DMA 分支引用未定义的 stm32_dma_config() → 当前形态会编译失败。
Kconfig UART defaults conflict with the BSP README’s documented default console (uart0).
Kconfig 的 UART 默认选项与 README 描述的默认 console（uart0）不一致。
PR process items: .github/ALL_BSP_COMPILE.json has no fm33lg026 entry, and the PR description template fields (config/action link) are not filled.
PR 流程项：.github/ALL_BSP_COMPILE.json 未加入 fm33lg026，且 PR 描述模板中的 config/action 链接未补全。

Replace embedded vendor library (FM/ + FM33LG0xx_FL_Driver) with the fm33lg0xx_fl_library software package (requires pkgs --update): - SConstruct: SDK_LIB points to packages/fm33lg0xx_fl_library - board/SConscript: startup file from package CMSIS layout - rtconfig.h: enable PKG_USING_FM33LG0XX_FL_LIBRARY - project.uvprojx: update MDK paths

- board/Kconfig: default UART0 on, UART1/UART5 off (match board debug port) - uart_config.h: fix UART5 config fields (.InitTypeDef + clockSrc) - drv_usart.c: remove STM32 legacy stm32_dma_config call, return -RT_ENOSYS
