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
