Hello,

I get this file in my board. What is the problem?

Updated all drivers, tried setting BOOT0 to high and then updated them but still nothing, any ideas?

P.S.

I tried to run one code was working fine. When tried to load other then this happend.

Hello

In STLink settings, change the reset options. Try "connect under reset" and / or use "hardware reset".

Just do what you tell me:

But get this error:

Hello,

No man still error. I think the problem is somewhere else. I tried under reset, pre-reset, normal. Still errors.

But I can connect to stm32 ST-LINK UTILITY 

But in KEIL program can't connect
