ContributorYour command sequence seems good to initiate a DMA transfer. Can you confirm whether streaming data is written correctly into the SGDMA? You may use SignalTap or simulation to check it.
New ContributorHi GNg,
Thanks for your response!
I also doubt that my streaming interface is a problem because I work fine with MM-MM. I did check it my streaming interface with Modelsim and also implemented it with Avalon FIFO, it works fine.
Maybe I will test it with SignalTap but I need to learn how to use because I have never used it before 😅 .
One thing also got my attention. At first, my counter's data width is 32 bits and data bits per symbol = 32. I got a warning that the mSGDMA data bits per symbol is only 8, if I want to transfer 32 bits data, I have to configure it to 8 bits data per symbol and 4 symbol per beat. I do not know how to change it to 4 symbol per beat. Whenever I change to 8 data bits per symbol ( with data width is 32 ) in "New Component" configuration window, it only transfer my 8 LSB data[7:0].
Once again, thanks for your answer. I will check on SignalTap when I have time.
