@bgouthamb Hi, I want to implement a simple OpenCV code using the reVISION platform. Can you tell me how I can edit the Makefile so that I can implement my example also.

Thankyou

[bgouthamb]

In the Makefile, for the APPSOURCES variable, put all the files that are being used, as you do with any general compilation. Next, you need to specify the function name, which you want to be implemented on FPGA, after the -sds-hw command followed by the file name in which the function is being called. The -files is for specifying the file in which definition of the function resides.

[bgouthamb]

This is the syntax : -sds-pf "platform-name" -sds-hw "function-name" "file-from-which-the-function-is-being-called" -files "file-in-which-the-function-definition-resides" -clkid "value" -sds-end

hi, I did that but then also it was giving various errors. Also I didn't use any of the xfopencv functions. I just used the standard opencv libraries.

hi, these are the errors that I am getting.

Okay. I think you got the concept wrong here. You cannot implement any kind of code on the SDx. The code has to be written in accordance with HLS & SDx(see UG902, UG1027 docs). Go through any of HLS and SDx examples to get the idea.

Please post in the Xilinx forums for any further guidance.
