I'm new to uVision for a University project and since trying to get my code to build on my PC at home I get this error with any code I try to compile. Anyone know any way to fix this? I've been racking my brain for hours trying to find a solution as I can't work on my project if the code won't even build. Thank you.
Make sure you have, or add, system_stm32f4xx.c to your project. Should be in your project directory for any STM32F4 HAL project.
I do have that file in my project (system_stm32f4xx.c (startup)). Is there something missing that I need to add to it or could the cause be something else?

is the file being built successfully?
and does it contain a definition of the missing symbol?
and that definition isn't being disabled by some #if condition ... ?

So have you talked to your tutor / lecturer / supervisor ?
WillJackman said:since trying to get my code to build on my PC at home
does it work on a PC elsewhere?
It doesn't build successfully, no. It says target not created with the aforementioned error message.By 'definition of the missing symbol' what do you mean exactly? I'm very new to this kind of stuff.
I have asked my lecturer and they don't know either. It worked before on University PCs but the software has been updated and it no longer works.

Hi I'm still having issues with this. Even with an example project downloaded directly from Keil, it still gives me this error: Undefined Symbol APBPrescTable, is there anything I can add to my code that would fix this?
Build one of the example or template projects. From *ST* https://www.st.com/en/embedded-software/stm32cubef4.html
Seems like your project is missing some meta-data, either in the command line defines for compiler, or paths for include files. Or the source is just not built/included in your project. Check for #ifdef block code inclusion.
Or you are mixing things from inconsistent sources.
