工程师你好，
我将pa_18xx_dss的EDMA初始化以及配置程序复制到高精度液位测量的程序下，代替原来的EDMA程序；
但是程序运行到EDMA_startDmaTransfer(obj->edmaHandle[EDMA_INSTANCE_A],
MMW_EDMA_CH_1D_IN_PING);出现错误；
错误提示如下：
[Cortex_R4_0] xdc.runtime.Main: "../APP/mss_main.c", line 795: assertion failure
xdc.runtime.Error.raise: terminating execution
[C674X_0] {module#38}: line 99: error {id:0x10000, args:[0x20034afd, 0x20034afc]}
xdc.runtime.Error.raise: terminating execution
为了说明我程序的正确性，我将附EDMA的相关程序；
