Dear all,
to get into programming the FX3 I tried to blink the LED on the FX3 Development Kit and tried to establish some debug messages via UART.
So I took the BootLedBlink Example Project and tried to build the UART function into it. I get a bit confused of what the library source ...FX3... and ...U3P... stands for. Seems to me that every function has a BOOT member and a U3P member. What is the difference between these two?
Nevertheless I now get a compiler error:
'Invoking: Cross ARM C Compiler'

I get this error even when I didn't use the cyu3dma.h header file.
