TI中文支持网ti 专家：
GIO_create 这个接口编译报错，屏蔽就正常，配置和报错如下：
1 cfg file
var DEV = xdc.useModule('ti.sysbios.io.DEV');
DEV.tableSize = 2;
var dev0Params = new DEV.Params();
dev0Params.instance.name = "mcasp";
dev0Params.initFxn = "&audioUserMcaspInit";
dev0Params.deviceParams = "&audioMcaspParams";
dev0Params.devid = 0;
Program.global.generator = DEV.create("/mcasp0", "&Mcasp_IOMFXNS", dev0Params);
var dev1Params = new DEV.Params();
dev1Params.instance.name = "audio";
dev1Params.initFxn = "&audioUserAudioInit";
dev1Params.deviceParams = "&audioParams";
dev1Params.devid = 1;
Program.global.generator = DEV.create("/audio0", "&Audio_IOMFXNS", dev1Params);
2 code
Error_init(&eb);
GIO_Params_init(&ioParams);
ioParams.chanParams = &audioChanParamsIN;
ioParams.model = GIO_Model_ISSUERECLAIM;
Vps_rprintf("ldq enter %s %d\n", __FUNCTION__, __LINE__);
inStream = GIO_create("/audio0", GIO_INPUT, &ioParams, &eb); <————– err
if (inStream == NULL)
{
Vps_rprintf("\r\nCreate input stream FAILED.\n");
BIOS_exit(0);
}

请问是什么原因？ 折腾好久了
Jian Zhou：
这个是在RTOS下跑的么？
