请教下为什么我在SDRAM里面定义了数组,但是想填数据就不行了

鲨鱼

u16 sdram_gImage_shuidi[2000] __attribute__((at(LCD_FRAME_BUF_ADDR+1536000)));        //定义最大屏分辨率时,LCD所需的帧缓存数组大小
        sdram_gImage_shuidi[0]=0xaa;
        sdram_gImage_shuidi[2]=0xbb;
        sdram_gImage_shuidi[4]=0xcc;
        sdram_gImage_shuidi[6]=0xee;
以上是我在SDRAM里面定义了一个数组,然后往数组里面填数据,但是这样就编译通不过,错误如下,请教下 这个是什么原因呢
