关于提供的EDMA demo edma_test.c中
/* Map the DMA Channel to PARAM Block 2. */
CSL_edma3MapDMAChannelToParamBlock (hModule, channelNum, 2);
/* Obtain a handle to parameter set 2 */
hParamPing = CSL_edma3GetParamHandle(hChannel, 2, &status);
if (hParamPing == NULL)
{
printf ("Error: EDMA Get Parameter Entry failed for 2.\n");
return -1;
}
按照注释是映射的PARAM Block 2中,可是阅读手册 edma 有64个通道,512个Param 参数集,没有发现块的概念,是先映射到block后,才能映射的参数集合?对这个概念不理解
