I have had similar problems.

I find by unplugging the USB and reconnecting will make the interface led go to a RED state, normally green after a download. Then it should load and work. Otherwise try a 'Compile All'.

Sometimes I have to compile/download the code image a second time if the DISCO-F746NG doesn't automatically start up after a download. The second time always seems to work.

Sometimes it had happened to me too. Anyway it came back to working after an unplug and plug again and/or a new compile and download code operation. I hope it will be as well for you.

Hello guys, i tried all the above but im still experiencing the same problem

Try downloading the compiled file to your PC, then copy to your 746 from the PC
