mSGDMA and On-chip Memory

Hi BadOmen,

I am quite new with Quartus.

So basically, I used Qsys to generate my hps component ans my system. I created 2 slave component(read and write) ( avalon memory mapped slave) and i can through the lightweight HPS-to-FPGA bridge map the address of the first slave (write) and write data. Also with the second one i can read data from it by the hps.

The problem is that the lightweight HPS-to-FPGA bridge has a capacity of 32 bits. So now, I would like to use the HPS-to-FPGA bridge which has a capacity of 128 bits.

I did the same thing that i did for the lightweight. but it doesn't work. I don't know why??

What is the difference between those two bridges? is there something to add (configuration)?

Could you please help me out from it?? It will be your great help!!
