I'm developing an application where I have to use IAP.
I downloaded IAP example from this site and for F407VG it worked just great.

But then problems occured.
I need this on STM32F401RE. 

IAP file is uploaded to stm, everything configured.
But when I try to download file from computer (.bin) to STM via USART it says that "Verification failed". 
I'm trying this in hyperterminal v7 and Ymodem protocol.

USART is working on IAP, because I got answer from chip and I can successfully press "1", which mean "Download .bin to STM".

What are main differences between this two cips? What I need to modify in program?

Thanks for answers
