A dead loop Bug

There is an infinite loop which is called when a hardware error occurs. Bad address, writing to code, executing protected areas, oscillator start fails and a couple of other reasons, all depend on the project. Best would be, because you are obviously in prototype design phase, to use a kitprog or a miniprog3 to debug your board and check the call stack to see what the cause is.

Is your program designed for SWD Debugging? cydwr-file->System->Debug Select?

Assuming you have triple-checked your soldering and not forgotten the needed caps for the power lines...

Consider posting your schematics and project here, so that we all can have a look at all of your settings? To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.

or

Create a support case (top of this page-> Design Support) Cypress will keep those information confidential.

To keep this discussion shorter,  can you post your complete project, so that we all can have a look at all of your settings? To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file. Some info about clock generation (Xtal?) can help. Call stack looks like a required clock does not start.

Bob

You use a BLE chip, but as for now you do not use the radio. I would suggest that your problem might have to do with the 24MHz crystal. Since you do not use it, try to remove it from the high-speed clock definitions (only) and see if something changes.

Bob

Some additional info:

Is Pin P2[3] unconnected (floating) and not connected to GND or Vcc

You get an undefined "abs" because you did not #include stdlib.h which will reveal two other errors.

OpAmp property should be set to "Internal only"

Bob

Yep!
