Hello,

I am very new to Cypress so sorry if this question may have an obvious solution.

I built a new project with a prepopulated schematic. When I started to add more components and my own code, I got an error message when attempting to build the API. "E1216: Routing of net __ZERO__ Failed. Source : :udb@[UDB=(1,0)]:pld0:mc0.q, Sink : :m0s8scbcell_0.rx ". I am not sure what this is coming from but I noticed that when I take out the I2C component, everything compiles. The problem is that I am intending on using an I2C for my project.

Another thing that I noticed was that the "source" part of the error message has "udb" in it. I was playing around with UDB in the project but deleted this part. Would this have anything to do with the error message?

Any help would be appreciated. Thank you in advance.

I am afraid that there are some remains from probing. Start over with a new project-

What do you mean by probing? Is there no way to remove the remnants?

Thank you for your fast reply.

I ended up rebuilding the project and found that this did not fix the problem. However, I found that, after building the new project, because the optimization, by default, is set to "extensive", it compiled fine. When I changed the optimization to "none", this was when the problem arose again. I tried changing the optimization to "normal" and now it is running fine.

I am glad the project is now working, but does anyone have any ideas as to why the optimization would do this? Just curious.

Thanks.

What is the Creator version you are using?

Latest version is Creator 4.0 I would suggest to upgrade and update the components. I admit, I never touched the fitter parameters, only the compiler optimization.

Will do.

Ah okay. I read some previous posts from you where you mentioned optimization but I was not sure which optimization you were talking about. Thanks.
