Thank you for your first answer. But I would like to copy data from Buffer on HPS to another/other buffer on HPS and the HPS has an DMA Controller - why should I use the FPGA DMA (speed is not so interesting)?

I have bind in the libs alt_dma.h and alt_dma_common into my main.c file. So every time when I uses fuktion from that libs (fokused alt_dma.h) I get linker error. Why doesn't work?

Thanks for your answer.
