DMA controller doesn't work properly

[Altera_Forum]

Hi everyone! 

I'm confused, because I really tried everything I could, but the DMA does not work. I use such functions:  /**  * Set transmit channel  */ static inline void moveTo(dhdlc_t *dhdlc, void *ptr, size_t blocksize){  IOWR_ALTERA_AVALON_DMA_STATUS(DMA_0_BASE,0);  IOWR_ALTERA_AVALON_DMA_RADDRESS(DMA_0_BASE,ptr);  IOWR_ALTERA_AVALON_DMA_CONTROL (DMA_0_BASE, TXDMA_CONTROL);  IOWR_ALTERA_AVALON_DMA_LENGTH(DMA_0_BASE, blocksize);   while ((IORD_ALTERA_AVALON_DMA_STATUS(DMA_0_BASE) & ALTERA_AVALON_DMA_STATUS_BUSY_MSK)); }  /**  * Set receive channel  */ static inline void moveFrom(dhdlc_t *dhdlc, void *ptr, size_t blocksize){  IOWR_ALTERA_AVALON_DMA_STATUS(DMA_0_BASE,0);  IOWR_ALTERA_AVALON_DMA_WADDRESS(DMA_0_BASE,ptr);  IOWR_ALTERA_AVALON_DMA_CONTROL (DMA_0_BASE, RXDMA_CONTROL);  IOWR_ALTERA_AVALON_DMA_LENGTH(DMA_0_BASE, blocksize);   while ((IORD_ALTERA_AVALON_DMA_STATUS(DMA_0_BASE) & ALTERA_AVALON_DMA_STATUS_BUSY_MSK)); }  where:  # define TXDMA_CONTROL (ALTERA_AVALON_DMA_CONTROL_WORD_MSK |   ALTERA_AVALON_DMA_CONTROL_BYTE_MSK |   ALTERA_AVALON_DMA_CONTROL_HW_MSK |   ALTERA_AVALON_DMA_CONTROL_QWORD_MSK |   ALTERA_AVALON_DMA_CONTROL_DWORD_MSK |   ALTERA_AVALON_DMA_CONTROL_GO_MSK |   ALTERA_AVALON_DMA_CONTROL_LEEN_MSK |   ALTERA_AVALON_DMA_CONTROL_WCON_MSK)  /**  * Receive control register setup macro  */# define RXDMA_CONTROL (ALTERA_AVALON_DMA_CONTROL_WORD_MSK |   ALTERA_AVALON_DMA_CONTROL_GO_MSK |   ALTERA_AVALON_DMA_CONTROL_LEEN_MSK |   ALTERA_AVALON_DMA_CONTROL_BYTE_MSK |   ALTERA_AVALON_DMA_CONTROL_HW_MSK |   ALTERA_AVALON_DMA_CONTROL_QWORD_MSK |   ALTERA_AVALON_DMA_CONTROL_DWORD_MSK |   ALTERA_AVALON_DMA_CONTROL_RCON_MSK)  The read/write addresses are set in my function before the usage of move_ functions.   Reading from memory to a peripheral does work well. But writing from a peripheral is partially done and than the BUSY reg is set and the whole transmission gets stuck :/  I have to admitt that the DMA controller in Quartus Prime 16.1 standard edition does work only for maximum of 64 bursts for txchannel...  Have anyone had the same bug/problem as I? I tried to use the Altera provided HAL functions, but register access works better.
