HW rebuild for other plaform

Hi,

yes you can retarget the device in hls-syn.tcl, in the make-hw.sh script and the make-vivado-proj.tcl.
Nonetheless, you're going to need to adapt also the the run-time SW running on the ARM cores, since the implementation is based on the XLNK driver for contiguous memory allocation.

Thanks! I am trying to do the co-sim in HLS and run into the following error. Do you have any idea what's wrong with that?

Hi,

for performance reasons, the host code embeds features of C++11, which is not completely supported in gcc 4.6.3.
You can try to instrument the host code to avoid C++11 non supported features, like the one listed here.
Hope this helps.

[joyliu37]

Um, make sense. Thanks!

[joyliu37]

I fixed the previous compile problem and run the co-simulation. It seems another problem related to the axi interface pop up. Do you have any idea? Thanks!

Increase the depth of the m_axi to the size of the data moved into the accelerator. You have to increase the depth value in lines 149, 151 and 153 in the top.cpp file.
