你好。目前我的开发包位：dvsdk_3_10_00_19，设置/sys/class/davinci_display/ch0/output错误，源码如下：
#define OUTNAME "Component"
#define OUTPUTPATH "/sys/class/davinci_display/ch0/output"
strcpy(command, "echo ");
strcat(command, OUTNAME);
strcat(command, " > ");
strcat(command, OUTPUTPATH);
if(system(command)) {
printf("Cannot set the output\n");
return -1;
}
程序运行到system，总是报错，不知道为什么不能设置Output参数
