Hello,

I'm using STR752FR0T6 in my project. For debug purpose, I loaded a simple program that toggles the LED using RTC in one second. When I power on, it sometimes runs and sometimes not. Firstly I thought the problem was about Reset Supervisor and I tried several Reset Supervisors including STM1818 which ST reccomends, but nothing changed. The same behaviour also occurs at Watchdog reset.

Do you have any information about STR752FR0T6 has a start-up problem or what can be the problem?

Text on the uC is:

Thanks.
