Hello, some time ago I started to play with CortexM4,
I bought a Discovery Board with a STM32F407VG in order to be programmed with uVision from Keil.
I am developing a project where the money is very restricted, that's why I was using a free licence from Keil.
Everything was working fine until I exceed the program size of 32KB(now I need to pay the license if I want to continue for this way).
I started to look for other option, and gnu-arm-none-eabi with Eclipse seems to be the answer.
The big problem are the peripherals: I need to use UART(to output message on debugging time using the famous "printf()") and SDIO to log some variables from different sensors that require I2C.
In general terms: what are the aspects that I need to consider when I switch those IDEs: from uVision to "System Workbench for STM32" known as SW4STM32.
