    Hi, all.

    I'm using STR755FR2 in my project(system 5vcc). For debug purpose, I loaded a simple program that toggles the LED using tim0 in 200ms. 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 STM1813 which ST reccomends, but nothing changed. The same behaviour also occurs at Watchdog reset.

    Do you have any information about STR755FR2 has a start-up problem or what can be the problem?
