RT-Thread Studio ART-Pi无法烧写外部Flash的问题的分析与解决

环境

• Win10 64位
• RT-Thread Studio 2.2.1
• ART-Pi 开发板：STM32H750XBH6开发板
• 工程：sdk-bsp-stm32h750-realthread-artpiprojectsart_pi_net_player

问题描述

• 使用RT-Thread Studio 进行下载，发现有的工程可以正常的下载，有的工程，怎么下载都是失败
• 对比了下成功与失败的原因，确认与硬件开发板没有关系
• 下载成功的信息：

问题分析

• 怀疑是下载算法引起的，查看工程的下载配置

• 正常工程的下载配置：sdk-bsp-stm32h750-realthread-artpiprojectsart_pi_blink_led

• 无法下载的工程配置：sdk-bsp-stm32h750-realthread-artpiprojectsart_pi_net_player
  
• 已经确定是没有【外部Flash烧写算法】引起的

解决方法

• 手动配置上烧写算法

• 配置完，可以正常的下载了
• 小问题：这个路径，与正常工程的路径，不太一样，后面研究如何配置和这个路径

正常的路径

${workspace_loc:/${ProjName}/board/stldr/ART-Pi_W25Q64.stldr}

手动配置的路径

D:/Gitee/sdk-bsp-stm32h750-realthread-artpi/debug/stldr/ART-Pi_W25Q64.stldr

• 手动配置的，是个绝对地址

小结

• 继续研究

最后
