Unfunctional DMA transfer @ Zynq-7000 (Z-turn Board)
I am trying to do a DMA transfer from DDR3-SDRAM to PL on a Z-turn board, but it doesn't work as expected. Please advise.
・The source address specified for DMA transfer is ".bss Section" in DDR, but it cannot be transferred even if it is changed to ".data section". (Try setting the source address to ".txt section in DDR" and the transfer works as expected.) ・Unexpected behavior means that data at the address specified by the master cannot be read. (Unknown data or 0x00000000 is read.) ・The operation is the same whether AXI-DMA-IP or AXI-CDMA-IP is used. ・The connection between PL and PS uses the AXI-HP port.
