硬件环境：dm6446
软件环境：dvsdk2.0.0.22
问题描述：
在dsp算法中，我想使用dma来进行算法优化，但是好像是在分配dma资源的时候出错了。
算法中关于dma部分的配置如下：
在server/*.cfg中：

DMAN3.heapInternal = "L1DHEAP"; /* L1DHEAP is an internal segment */ // DMAN3.heapInternal = "DDRALGHEAP"; /* DDRALGHEAP is an external segment */ DMAN3.heapExternal = "DDRALGHEAP"; DMAN3.idma3Internal = false; DMAN3.scratchAllocFxn = "DSKT2_allocScratch"; DMAN3.scratchFreeFxn = "DSKT2_freeScratch"; DMAN3.paRamBaseIndex = 80; // 1st EDMA3 PaRAM set available for DMAN3 DMAN3.numQdmaChannels = 8; // number of device's QDMA channels to use DMAN3.qdmaChannels = [0,1,2,3,4,5,6,7]; // choice of QDMA channels to use DMAN3.numPaRamEntries = 48; // number of PaRAM sets exclusively used by DMAN DMAN3.numPaRamGroup[0] = 48; // number of PaRAM sets for scratch group 0 DMAN3.numTccGroup[0] = 32; // number of TCCs assigned to scratch group 0 DMAN3.tccAllocationMaskL = 0; // bit mask indicating which TCCs 0..31 to use DMAN3.tccAllocationMaskH = 0xffffffff; // assign all TCCs 32..63 for DMAN |
在算法中也参照demo实现了IDMA3_Fxns接口函数，编译通过，运行时出现的错误截图如下：
对应的log信息如下：
