connecting onchip memory or SDRAM to the HPS using HPS to FPGA bridge

Hello,

Did you figure out a way around the problem?

I'm trying to do something similar... Maybe you can help.

I want to write data into SDRAM (or any memory for that matter) which is then read by FPGA. After processing, it writes back to a memory space from where the HPS reads these 'FPGA results'.

For now I have a SDRAM controller in my Qsys design (base address 0x0800_0000).

So to write from the HPS I use the lw bridge? For example:

alt_write_word(lw_bridge_map+ SDRAM_BASE_ADDRESS ,0x50);

Is this the right way to do it?

Then how do I access this newly written data from the FPGA?

Your thoughts would be appreciated.

Thanks.
