Honored ContributorHi there,
The descriptor_slave should connect to the .data and .instruction Master of your NIOS processor. To my understanding, this is where the descriptors are written to when you call construct_standard_mm_to_mm_descriptor(). The Data_read_master connects to your memory where the source data resides, and the write data master should connect to the memory where you want the source data to be written. The error you are having seems to be caused by the BSP having the wrong settings. In my case, it didn't recognize a timestamp function, eventhough it sees the required header file in the project tree. I still managed to generate the BSP, just not the project containing my DMA controller code. Hope this helps.
