seems no big issue, and u may run sw_emu first.

[justinjiaxinghu]

what do you mean no big issue? Are you saying that I should make with sw_emu first and then do hw_emu?

[lloo099]

Yes. I run sw_eni successfully but failed in he

Yes. I run sw_eni successfully but failed in he

I'm confused. are you saying you're having the same issue? I am also failing on make hw_emu after running sw_emu

Yes, u May check #165

update on this issue:

I actually think it has something to do with the ifdef statements. I switched to VGG and for some reason had to manually comment out the stream variables corresponding to the resnet model for things to compile properly. additionally, the config file needs to be modified when you switch networks as well. I hope this can be helpful to others, but I also hope these issues will be worked out in a future commit

Thanks much. Could you provide modified codes to help us?

For xilinx platform, only VGG is supported now.

Hi, I encounter a problem about Memwr. When I run this .exe, the system is no response at Kernel MemWr for long time. Do u know how to solve it? It seems no feedback from device

I didn't encounter this error so I'm unsure. I also used the u50 board. It seems you have jumped over all the other compilation hurdles, though.

Anyways, I'll outline the changes I had to make to make VGG compile and run (at least for hardware emulation).

If you are using the default makefile provided, you shouldn't need to make any changes other than the following for the makefile (also just change the flag from sw_emu to your desired setting as specified in the user instructions).

HOST_SRCS = ./host/main_aoc.cpp ../../common/ocl_util.cpp ../../common/timer.cpp
#use Xilinx OpenCL C++ host binding
#HOST_SRCS = ./host/main.cpp ../../common/xcl2.cpp ../../common/timer.cpp
HOST_OBJS = $(HOST_SRCS:%.cpp=%.o)
HOST_INCS = ../../common

change to

HOST_SRCS = ./host/main_aoc.cpp ../common/ocl_util.cpp ../common/timer.cpp
#use Xilinx OpenCL C++ host binding
#HOST_SRCS = ./host/main.cpp ../../common/xcl2.cpp ../../common/timer.cpp
HOST_OBJS = $(HOST_SRCS:%.cpp=%.o)
HOST_INCS = ../common

The config file:
Make sure to uncomment out the lines under VGG connection and comment out the ones for Resnet

The code:
Under project_xilinx/devices

In memWrite.cpp

#ifdef RESNET
				uchar  bypass,
				uchar  pool_pad,	  //RESNET need pad,set to 1,other CNN set 0
#endif
...
...
...
#ifdef RESNET
				hls::stream<k2k_data_xlane>     &bn_in,
				hls::stream<k2k_data_xlane>     &bypass_in
#else
				hls::stream<k2k_data_xlane>     &conv_in
				//hls::stream<k2k_sync>           &pool_sync_out
#endif

Change to

/*#ifdef RESNET
				uchar  bypass,
				uchar  pool_pad,	  //RESNET need pad,set to 1,other CNN set 0
#endif*/
...
...
...
/*#ifdef RESNET
				hls::stream<k2k_data_xlane>     &bn_in,
				hls::stream<k2k_data_xlane>     &bypass_in
#else*/
				hls::stream<k2k_data_xlane>     &conv_in
				//hls::stream<k2k_sync>           &pool_sync_out
//#endif

I am unsure why these have to specifically be commented out. If I didn't, I got some invalid port errors.

Under project_xilinx/host

In main_aoc.cpp

The user defined library paths are incorrect

// user defined library
#include "ocl_util.h"
#include "timer.h"

change to

// user defined library
#include "../../common/ocl_util.h"
#include "../../common/timer.h"

hope this helps some people, hopefully i didnt miss anything

How did you solve this problem? I also encountered this problem
