我用移远的EC800G模块，f1c100s+linux 4.15， USB识别ttyUSBx，不断探测->断开->探测

f1c100s跑rtos, 配置DMA为NDMA模式，0通道。

源DRQ为0x0C : Audio Codec， IO Mode，目的DRQ为0x11，Linear Mode : SDRAM Memory，Data Width：16-bit， Burst Length：4，音频采样8kHz， mono单通道。按采样20ms计算：8000*16*0.02=320字节，结果采样只有160字节。DMA方式20ms，codec只有160字节。DMA完成后，只采集到160字节

NDMA_BYTE_CNT_REG设置为160

NDMA采样 Full Transfer Interrupt模式触发

采集流程：开始DMA音频采集->DMA FULL中断触发->中断函数重设DMA音频采集->如此循环。 DMA的目的地址映射到一个循环缓冲区。

用的是f1c100s芯片，@ntmusic的《基于RTThread的F1C100s开发(带boot启动+硬件多图层+硬件游标+LVGL+SDIO)》的allwinner_tina_prj_v1.rar文件，增加了speex库，编译通过，链接就出问题了

djslion · 全志 SOC

大家好，我在rtt的allwinner_tina包中加入了speex编译，编译器为gcc，链接时候出现以下问题，不知道是不是链接脚本的问题。麻烦大家帮忙看一下。谢谢

@卓林
感谢兄台

卓林说：

真的是非常抱歉，问题解决了。我也不知道怎么回事，我把整个内核重新编译一遍之后就可以了。
非常感谢您的回复@司徒

卓林兄，能把内核分享出来吗？谢谢
