Hello,

Above part of code is a part of my custom IP. I just want to write some data in SDRAM on click of a button as can be seen in the above code. I added this part to write some data in SDRAM. I am using Master Write Template in Qsys to do so. From my custom IP I am giving below signals to Master Write Template (IP in Qsys):

myBuffer_control_write_fixed_location

myBuffer_control_write_write_base

myBuffer_control_write_write_length

myBuffer_control_write_go

myBuffer_user_write_buffer_input_data

myBuffer_user_write_write_buffer

Attached is the Qsys snap.

Right now I am only considering the write operation. I have a top verilog file in which i connect the exported signal from my custom hardware to the exported signal from Master Write template. And Master Write template is directly connected to SDRAM.

Please let me know if can help with more details.
