module 'zedbd' not found #2

Closed wsong83 closed 7 years ago

Hello Furkan,

I try to follow your instructions to run the Zedboard demo, after I trying make hello (the first time to synthesize the project), Vivdao complains about module 'zedbd' not found in Wrapper.v

It does not seems like a library component. Am I miss some steps or maybe there is indeed lack of source files?

Hello Wei,

Sorry for the problem. It is happened probably because we use different versions. I am using Vivado 2016.2, and which version do you use?

zedbd is the block design I created in Vivado and exported as a tcl file. You can find it in scripts folder. When sourced, it should create the block design named zedbd. You can check the block design by opening the GUI with make project and thenmake vivado.

I have access to old 2015.2 version as well, and created another zedbd.tcl for this old version. Then I replaced it with the existing zedbd.tcl file in a new branch named 2015. It should work now.

Now, I am worried about the programming with make program. As I explained in the tutorial, fpga design depends on ARM processing system. Therefore, the program.tcl script initialises ps7 by executing predefined ps7_init.tcl on xsdk in batch mode. This is the method I used first time in this project, and I don't know if there is a difference in xsdk functionality between the two versions, but I will try to check it soon.

I see. Currently I use 2015.4 and 2016.4 but I can install any version if needed. I hope the project should not be tied to a single version of Vivado. This feels a little bit odd for the error on my side. I will have a better look tomorrow. Thanks.

It is caused by an unnecessary version check which can be removed. PR #3 tries to fix this issue.
