C5535 CSL.DMA 库函数问题

技术人员，你好。我是一名研究生，在用EZDSP5535做一个音频信号采集系统。需要用到DMA直接在AIC3204和内存间传输样本文件，但是目前的C5535 CSL.DMA 库函数（C55XCSL-LOWPOWER-3.03.00_Installation_Guide）里面没有写明支持5535这款芯片。请问有5535专用的库吗？

    你好，

    这个CSL库支持5535, 在installation guide里有说明在C5535 eZdsp板子上验证过。

    dear TI-professor

         I'm a college student from China,and nowdays I'm studying EZzdsp 5535 develop board, and i want to use it to record voice and play it back.BUT ,I just meet some problems .
          First , i have found that the latest CSL doesn't support CHIP 5535. and the file in general.h show that the CSL only support 5504,5514,&5517.but not include 5535.
          Second, 5515 use I2S0 to connect AIC32xx's DOUT AND DIN pin, and the CSL support it .but the 5535 use I2S2 connects AIC3204,so that I can't Use DMA to transfer data between SARAM and Peripheral(AIC3204).
           Third,the test project give in the tests file ,can't record voice ,I can only hear 1KHz noise from "aic3204_tone_headphone.c",but "aic3204_loop_linein" seems doesn't work , because i can't even hear any voice.
          All i want,is to record voice , then analyse it ,then play it back . could you please help me out ? I'd be very thankful  if i can get your reply  letter.
         my email is 1347840731@qq.com. wait for your reply .thank you very much !
