Posted on August 06, 2012 at 21:25You seem to have attached a number of standard library files, and not some of the include files unique to your project, along with a subset of your files. Please always ZIP up and attach a stand-alone, complete, buildable example if you want someone to dig through it.
The BMP is badly cropped, I'm not sure what information is being conveyed. HyperTerminal is a pretty awful application, Tera-Term or Real-Term.
I'll note that when writing to the TX register you should front test whether the register is empty, not back test it to see it has been consumed.
Do some debugging, perhaps output some strings, or make a simple monitor program so you can interact with your boards and devices.
Be cognizant that the STM32F4-Discovery board has an 8 MHz external crystal, and a lot of the example code assumes a different board with a 25 MHz crystal, and will thus get the PLL and baud rate settings fouled up.
