Hello there! I'm using STM32F407VGTx and Keil U5. Everything went well but when I run the simple code of blinking led on board it doesn't blink at all and the screen says zero errors. Anyone knows how to solve it?
Having no syntax errors is not a guarantee of functional code.
You're going to have to review what you're doing, making sure the correct clocks are enabled, and you've configured the pins properly.
Use a debugger, single step the code, confirm peripheral registers contain appropriate values. Review the reference manual, surely this contains much detail related to the part.
Do I need to run the code again in a debugger?
I don't know, do you want to understand what's happening? The alternative is to use static-analysis where you review the code thoroughly by inspection.
You describing things as "not working" doesn't really constrain the problem very tightly.
Remember that we know nothing about you, or your code, or what setup you have other than what you give in your posts.
We cannot see you, or your bench, or your computer screen.
That's why you need to provide a full description of what, exactly, you have and what, exactly, you have done, and what steps you have taken to resolve the problem.

I put my code in c:\my documents and code\code\project\code\source\arm\STM32F407VGTx\arm\source
can u look and help fix the problem
Think about it: we also cannot access your computer's hard drive - can we?!
Do you not have teachers / co-workers / supervisors who can help you with this?
i now make it sharable. it is got the name KEILHELP and i give write premissions
