From b8803c3ab79a696bb192802b836ebe6fc3db9f64 Mon Sep 17 00:00:00 2001 From: godmial Date: Fri, 28 Nov 2025 15:41:58 +0800 Subject: [PATCH 1/2] =?UTF-8?q?feat(gd32):=20=E4=BC=98=E5=8C=96GD32F470=20?= =?UTF-8?q?SPI=20Flash=E5=88=9D=E5=A7=8B=E5=8C=96=E5=92=8CUART0=E9=85=8D?= =?UTF-8?q?=E7=BD=AE?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 主要修改： 1. SPI Flash初始化优化 - 添加可配置的SPI Flash自动初始化选项(BSP_USING_SPI_FLASH) - 支持按SPI总线独立配置Flash初始化(BSP_USING_SPIx_FLASH) - 避免SPI Flash初始化与其他SPI设备(如OLED、WIFI)冲突 - 添加SPI5 Flash支持 - 修改drv_spi_flash.c，仅在明确配置的SPI总线上初始化Flash 2. UART0配置修复 - 将UART0的AFIO默认值从AF1改为AF7 - 修复串口无响应问题 这些修改使得用户可以更灵活地配置SPI Flash初始化，避免自动初始化导致的设备冲突问题。 --- bsp/gd32/arm/gd32470z-lckfb/.config | 2 +- bsp/gd32/arm/gd32470z-lckfb/board/Kconfig | 56 ++++++++++++++++++- bsp/gd32/arm/gd32470z-lckfb/rtconfig.h | 2 +- .../libraries/gd32_drivers/drv_spi_flash.c | 28 ++++++++-- 4 files changed, 80 insertions(+), 8 deletions(-) diff --git a/bsp/gd32/arm/gd32470z-lckfb/.config b/bsp/gd32/arm/gd32470z-lckfb/.config index 62ab51945f6..0798ecfb021 100644 --- a/bsp/gd32/arm/gd32470z-lckfb/.config +++ b/bsp/gd32/arm/gd32470z-lckfb/.config @@ -1447,7 +1447,7 @@ CONFIG_BSP_USING_SERIAL_V1=y CONFIG_BSP_USING_UART0=y CONFIG_BSP_UART0_TX_PIN="PA9" CONFIG_BSP_UART0_RX_PIN="PA10" -CONFIG_BSP_UART0_AFIO="AF1" +CONFIG_BSP_UART0_AFIO="AF7" # CONFIG_BSP_USING_UART1 is not set # CONFIG_BSP_USING_UART2 is not set # CONFIG_BSP_USING_UART3 is not set diff --git a/bsp/gd32/arm/gd32470z-lckfb/board/Kconfig b/bsp/gd32/arm/gd32470z-lckfb/board/Kconfig index 2cf71f29b7c..c152c757198 100644 --- a/bsp/gd32/arm/gd32470z-lckfb/board/Kconfig +++ b/bsp/gd32/arm/gd32470z-lckfb/board/Kconfig @@ -53,7 +53,7 @@ menu "On-chip Peripheral Drivers" config BSP_UART0_AFIO string "UART0 alternate function, such as AF7" -
