Problem with converting files

Hi! I need to create double buffer in my NIOS II project. I did it as follow: static const uint32_t image_width = 768; static const uint32_t image_height = 576; typedef uint32_t gui_frame_t[image...

Hello RSher11,

I'm looking into your issue.

You can try these next steps and tell me what's happen?

1) add a new region called .video_buffer and assign it to the emif linker region / memory device name (they have already done this)

​

2) in the lower section of the window: Linker Memory Regions, click Add and give the name of the new region video_buffer with a memory device name set to emif

​

3) adjust the size of the original emif (I reduced it in half) and set the video buffer depth to half of what I had available

​

4) after building the bsp, and writing a simple hello_world program to intialize the video buffer and print it out, my elf size is approx 6KB

Best regards.

Hello, Isaac_V_Intel,

Sorry for the late response. I tried to create small test project on your recommendation. It worked. But when I tried to use your solution in my working project I got that issue again.

I attached some additional information about program size for my test and working project respectively.

Info: (my_project.elf) 3548 KBytes program size (code + initialized data).
Info:                  65436 KBytes free for stack + heap.
Info: (my_project.elf) 13386 KBytes program size (code + initialized data).
Info:                  63801 KBytes free for stack + heap.
