TI中文支持网我们使用EVMK2G开发板，
音频板是参考PCM1864-Based Circular Microphone Board (CMB) Reference Design资料自己设计的13通道，我们接EVMK2G使用了8个 通道
程序使用SDK开发包ti-processor-sdk-rtos-k2g-evm-04.01.00.06-Windows-x86-Install，使用demo程序为realtime_demo_bios
调试过程中，DSP可以正常启动，启动后电流大约0.56A，主程序运行到mcaspAudioConfig()会报错误；
/* Initialize McASP module */
status = mcaspAudioConfig();
if(status != Cmb_EOK)
{
cmb_write("McASP Configuration Failed!\n");
UART_printf("McASP Configuration Failed!\n");
testRet(1);
}
/* Start BIOS execution */
BIOS_start();
///////////////////////////////////////////////////////////////
进入status = mcaspAudioConfig();程序单步调试；发现程序进入
status = mcaspCreateChan(&hMcaspRxChan, hMcaspDevRx,MCASP_INPUT, &mcaspRxChanParam, mcaspAppCallback, &rxChanMode)中报错;
console 输出错误信息如下：

Audio Preprocessing Demo******************************************
This Demo Takes the Audio Input from 8 Mics from CMB
Runs the BF+ASNR+MSS+DRC Signal Processing Chain on Mic1 through Mic7
The Processed Audio Output will be Sent to Left Channels of K2G EVM On-Board Line-Out
The Mic8 will be Sent to Right Channels of K2G EVM On-Board Line-Out
Please Plug a Headphone to K2G EVM On-Board Line-Out

请哪位高手，分析指导一下，我们在调试过程中，那些操作不正确，导致realtime_demo_bios 演示程序 无法正常运行；谢谢！

请问是否有参考过下面的文档里的步骤来连接硬件?http://www.ti.com/lit/ug/tiducr7/tiducr7.pdf
