Hi everybody. I have a problem that's driving me nuts.
I need to write some datas from pc to DDR memory of my Zedboard. Once writing is complete, I need to read all the datas with a custom vhdl ip-core.
I made something similar using BRAM port and AXI_BRAM_Controller and it worked just fine, but the BRAM memory isn't big enough (about 2 MB max). I need to be able to set my memory size to, I would say, 20,30,50 MB or more.
I red about CDMA and others but I don't understand how to read datas with custom vhdl (with BRAM port was quite easy since it has a simple interface).
Thank you for your answers (will be very helpful!).
