The network works only in debug mode, I have no ping at all in non-debug mode.

Hello,

I did all the settings exactly like ST's examples, but I can only get a ping when I'm in debug mode, when I exit debug or power up the microcontroller I get no ping!

Please guide me if you know where the problem is.

Hello,

sorry for later reply, I missed the notification.
This might be caused by not initializing RAM properly in startup code. The debugger might initialize the RAM before starting the program.
Does this happen with the examples provided in repository?
