ld修改如上

定义变量

1. static uint8_t Read_Buff[480*272*2] __attribute__(( section(".SDRAM"), aligned(4) ));
   
2. static uint8_t Write_Buff[480*272*2] __attribute__(( section(".SDRAM"), aligned(4) ));

复制代码

    for(int i= 0; i<4;i++)
    {
    Read_Buff = str;
    }

编译是通过了

下载出问题

这个能编译，不能下载进去能解决不。  SWMPROGAM 下载一直在写flash  停不下来

如果 SWD 下载有问题，，可以试下 ISP 下载，，ISP 下载是解救芯片的终极手段。。

左上角“资料下载”链接中有 ISP 上位机软件。。

关键是写不进去，程序不能运行
LD 文件还是有问题
