Hello!

Code generation by stm32cubemx 4.7 is very, very slow. About 30 minutes.

I use windows 8.1. Project file attached

I'm not seeing this on an XP virtual machine running under VMWare on a MacBook Pro using 4.7.0 under CubeMX 1.0 standalone.

For a reasonably complex project on a 32F407, with FatFS, CAN, ADC, DAC, RTC, SPI, SD, 8 timers, 3 UARTS, random number generator, etc. I'm getting about 80 seconds.

Using your project, the time is less than 30 seconds.

This bug reproduced on 2 PC's with Windows 8.1. This bug not exists in previous versions of cubemx.

I found possible root of this problem. After every code generation .project file size increases. After first code generation size=13k, after second size=23k, etc.

Fast hotfix - remove .project file before code generation

Here you can see difference in file creation time (and file size after some regenerations).

Hello!

How to reproduce:

1) Create new project

2) Select TrueStudio as IDE

3) Press Generate Code. Make backup copy .project file

4) Press Generate Code again. Compare size of .project file with backup copy

5) Repeat step 5. On every code generation file size increases.

This is lenovo t540p with preinstalled Windows 8.1 x64.
