Is it possible to use DDR3 without configuring it from the QSYS hardprocessor? I want to use DDR3 for the boot up of the HPS. What should be the steps i need to follow. Thanks.

Hi,

As per my previous experience,

Although you are not using any logic in the FPGA, you have to use Quartus tool & Qsys. In the QSYS, configure the HPS with required IO muxing & boot source & HPS DDR3 configurations. Then just write a verilog/vhdl top module instantiatin the QSYS system.

Then compile the Quartus project & use the sopcinfo & FPGA binary for generating the HPS binaries like preloader, uboot etc. To generate HPS binaries, I think SOC EDS tool is used.

Hello HPB,

Thanks for your reply.

it helped me allot.

now i have our own development board with DDR3 (MT41J128M16JT-125:K) and SoC (5CSEBA5U23I7N) on it.

i am now able to run the baremetal on chip memory by following this tutorial.

https://www.intel.com/content/www/us/en/programmable/documentation/lro1424280108409.html

Now i get the following error if i want to use "Create a New Scatter File to Locate the Bare Metal Application in the SDRAM"

ERROR(CMD16-TAD274-NAL22):

! Failed to load "bare metal-hello-world-01.axf"

! Failed to write 4,896 bytes to address S:0x02000000 while writing block of 4,096 bytes to address S:0x02000000

! General error on memory or register access.

Is there any method to debug why i get this error?

in my memory view of DS-5 i cant see the DDR3 memroy (my program runs in the endless loop)

Is there any possibility to move forward.

thanks.

:)

i forgot to mention in my question that,

I am getting this failure with and without the scatter file.

which address of the DDR3 memory should i use in my scatter file.

the scatter file which i am using is mentioned below.

SDRAM 0x02000000 0x02000000 ; 32M SDRAM

{

APP_CODE + 0

{

* (+RO , +RW , +ZI )

}

ARM_LIB_STACKHEAP 0x03000000 EMPTY 0x01000000 ; Application heap and stack

{ }

}
