Opened this issue · 4 comments
Hello! I have a question!
When i start the C simulation, error is occur at line number 94 in fpga_top.cpp
Error message is below.
CPU: Offload CONV Layer c10/p1: 8x8 x 736 > 512, CONV (1x1)/1 , IN @mem(13295616-13484032B), OUT @mem(13484032B), WEIGHTS @mem( 7096448- 8605824B) (split1) GLOBAL POOL

How can i solve it?
I don't know how can i go to next step.
when i run the csim.exe in my project path which is below.
C:\Users\ksg\Documents\GitHub\zynqnet_HLS_CODE\zynqnet_ksg\solution1\csim\build\csim.exe
the error is occur again like below

How can i solve it?
I look forward to your comment.
Thank you!
Thank you for your response.
i fixed SHARED_DRAM size in cpu_top.cpp file at line number 207.
SHARED_DRAM = (char *)malloc(total_size);
=>
SHARED_DRAM = (char *)malloc(total_size ** *2 ** );
and it's working!
Thank you so much!
hello, guys!
I met the same problem and I tried to change SHARED_DRAM to twice as it was, but it doesn't work as I expected and there is still sigsegv error.
is there any other possible reason or solution?
Thanks a lot!

you can try to delete “blobs/” in fpga_top.cpp
