器件型号：TMS570LC4357 主题中讨论的其他器件：LAUNCHXL2-570LC43
您好！
我希望 您在这段困难的19岁大的时期内保持健康。
我已经下载了一个从 QJ Wang 构建的关于电路板 LAUNCHXL2-570LC43的项目
当我尝试 将代码加载到主板时 ，我收到了以下消息：
CortexR5：加载程序：程序的一个或多个部分落在一个不可写的存储器区域中。 这些区域实际上不会写入目标。 检查链接器配置和/或存储器映射。
CortexR5：文件加载程序：验证失败：地址0xF0407FF0处的值不匹配请验证目标存储器和存储器映射。
CortexR5：GEL：文件：C：\Users\PC_1742_admin\Desktop\Hercules_Ethernet_Bootloader_deleted\build-LAUNCHXL2-TMS570LC43x-tftpboot\Debug\build-LAUNCHXL2-TMS570LC43x-tftpboot.out：发生数据验证错误、文件加载失败。
当我关闭 DE 验证时，会显示如下消息：
CortexR5：加载程序：程序的一个或多个部分落在一个不可写的存储器区域中。 这些区域实际上不会写入目标。 检查链接器配置和/或存储器映射。
我在 main.c 中更改了 GJ Wang 代码，如下所示；
