Writing data to EPCQ user memory

I want to write some Application specific data to the user memory in EPCQ128. How do I do that and what are the addresses available for me to write data?

Hi, 

 

Basically you are free to organize the entire flash memory based on your needs. One of a way to store file in flash memory would be using the Read-Only Zip File System. Please refer to https://www.altera.com/en_us/pdfs/literature/hb/nios2/n2sw_nii5v2gen2.pdf section 12 for details.

Hi, 

 

I'm not sure whether that was what I was looking for. I'll post my requirement clearly. See if you can help. 

 

I want to write some application specific user data on the EPCQ128 in a Cyclone5 board and then read the same. For reading data from the EPCQ I use the Altera ASMI Parallel IP. How do I initially store the data in the EPCQ using the Active serial interface?

Hi, 

 

Please take a look into AN736 (https://www.altera.com/en_us/pdfs/literature/an/an736.pdf). You will need to create a hex file (your user data) and convert it to JIC file before program into EPCQ using Quartus Programmer.
