Hi,

I'm writing a code that works fine when I program directly via Keil with this settings

However if I compile the project and write hex file with stm32 st-link it doesn't work fine. It is good to mention that I active ''read out protection'' bit.

my means is that I my Ethernet protocol didn't work when I program with st-link however it works fine when I program it directly via keil with the same programmer.

Try not enabling read-out protection and do a byte level verify. Heck have your own code checksum the image it is trying to execute, and make a determination if they are actually writing different things to flash.
