+ **================= IAR WARNING =================**
+ 
+ after use `scons --target=iar -s` cmd to product IAR project, you have to add iar link file by hand
+ 
+ IAR steps:
+ 1. Project-->Options-->Linker
+ 2. Config-->Linker Configuration file
+ 3. select `Override Default`, then select `bsp/stm32f40x/stm32f40x_flash.icf`
+ 4. rebuild project
+ 
+ 
+ **TODO**
+ auto add *.icf by scons script
