Hello,

I'm using IAR and I configured stm32f429 discovery board by STCubeMX and its libraies.
It seems to work fine when I run my code with Download and Debug mode.
But when I exit debug mode the board stop running immediely even if I downloaded my code into flash memory.
I have no idea what I shoud fix in order to make the board run without debug mode. 
Please help if anyone know about this issue. 

Best regards,
