Hi team,
I am trying to excute mdma from L1 memory to SMC interface which is connected to FPGA. In my test code mdma works fine, but in the target program mdma stalls.
Registers right after mdma requested:
DMA8: CFG 04000201 STAT 00006000 AddrStart 282601e8 Cur_Addr 28260204 Cur_XCNT 0000000c
DMA9: CFG 04200203 STAT 00006200 AddrStart 44000100 Cur_XCNT 00000013
mdma configuration:
srcTrans.XModify = 4;
srcTrans.YCount = 1;
srcTrans.YModify = 4;
srcTrans.pStartAddress = (void*)input.GetPointer();
srcTrans.XCount = len;
dstTrans.XModify = 0;
dstTrans.YCount = 1;
dstTrans.YModify = 0;
dstTrans.pStartAddress = (void*)ULB0_DATA_S;
dstTrans.XCount = len;
ret = adi_mdma_Copy2D(hStream, ADI_DMA_MSIZE_4BYTES, &dstTrans, &srcTrans);
When I transfer the data like followin codes, there is no problem.
while (len>0){
*ULB0_DATA_S = *saddr;
saddr++;
len--;
}
Please let me know if you find any possible causes.
