AD9467FMC + ZEDBOARD :Modify max buffer dimension on  AXI_DMAC IP

I'm using  a AD9467FMC-250EBZ + ZEDBOARD, with SDK project.

I use the reference design : hdl/projects/ad9467_fmc/zed at master · analogdevicesinc/hdl · GitHub

I'm using an 80MHz clock ADC.

I must read a buffer of adc sample with a dimension of  64 MByte ( 32 M sample), but the

max dimension of "lenght X" is 16MByte ( only 24 bit is used) in axi_DMAC IP.


How can i expand the dimension of data captured without loss sample ?


I opened the design firmware and  i saw the possibility of programming the Lenght X and Lenght Y,

Can i use this mode for  my acquisition ? In this case which is the software interface ?


Best regards
