Zynq DDR Access

Hi all,

I have a ZCU111 board and I am trying to access the DDR though the Zynq but the bus never seems to be accepting any transfers.

Does the Zynq have to be running in a particular mode to allow access to the DDR through it?

Thanks,

Jas

I am using the ZCU111 and can access the PS SDRAM (XPAR_PSU_DDR_0_S_AXI_BASEADDR) through the a DMA engine connected to the S_AXI_HP0_FPD on the ZYNQ.I can use the XSCT consul to read SDRAM contents after the DMA.

You have to make sure the DDR is enabled in the Zynq setup and your interfaces are connected correctly.

Good luck.
