Is there a free/lite Keil MDK for STM32F4?

According to this page 

http://www2.keil.com/mdk5/selector/

 the Lite Keil edition does support Cortex-M0/M0+/M3/M4/M7.

Does STM's F4 series belong to the category of ARM M4? If yes, why the Lite MDK license does not let me to target STM F4 boards such as Nucleo?

(If this is relevant, I've already requested a license for STM F0 on my machine successfully, because earlier I played with STM F0 device. But now I need to switch to F4)

Regards,

Pavel

You have installed the STMicro M0/M0+ license, this is going to limit your usage of that installation.

The Keil Eval can build up to 32KB images for the F4 designs, beyond that you're expected to buy your own license, and would need to if using the code commercially.

I would just add that you can use the Keil IDE and compile with the GCC compiler (not supplied by Keil) without the 32KB limitation, however the 32KB limit would still apply to debugging. I did this before eventually purchasing a Keil license.

Another way of working is to rely on SystemWorkBench for STM32 tool :

http://www.openstm32.org/Downloading%2Bthe%2BSystem%2BWorkbench%2Bfor%2BSTM32%2Binstaller

Such is :

1) Fully free

2) No code size limitation

3) No private / commercial usage limitation

4) Fully relying on ARM Gcc toolchain (same or even more recent release then Keil MDK ...)

5) Supporting full STM32 portfolio devices & related boards

Have a try !

And, of course, you can also use Eclipse with ARM GCC - so all of the above, plus no vendor lock-in (but you have to do all the setup yourself).
