How to write/read data to DDR in NIOS II eclipse tool ?

[Yogesh]

suppose I have an array of data as below

array[10000] = {1,2,3,4,5...................10000};

How to write this data in 10000 address locations of DDR?

Please reply with a sample code

Hi Yogesh!

The way for doing this depends on what you're using :

• For HPS DDR please take a look to this Data mover sample design
• For FPGA DDR use this design as reference

Do not hesitate to let me know any questions you may have .

Hi Eliath,
I am interested in the 2nd design (FPGA DDR)which you mentioned.
I went through the design provided by you . But I didn't find the c code( NIOS eclipse code) which is used to store data in DDR .Am I seeing something wrong?
I just want to understand (code wise) how data is written to FPGA DDR using Eclipse c code.
Please guide me.

Thankyou
Regards
Yogesh

Hi Yogesh,

Hoping you're doing well, I wonder if I can close this thread,

I found another post of you with almost the same question and I've seen

my colleague gave you a solution.

Is there anything else I can do for you?

Best regards,
