STM32F103 resetting

Hi,

I have an STM32F103RC8 controller board. I have two LEDs connected to two port bits. When I load a using flash loader demo program to toggle the LEDs the program works for a few seconds and the controller resets. If I put the boot 0 pin to boot from application the controller resets much faster. The program is very simple. Initialize GPIO port bits (only those connected to LEDs) and a while loop with a delay routine. What could be wrong? I am sure there is nothing in the program. Thanks for your time and help.

Hi nayani.partha,

Please give more details :Which board you are using ? is there any external connections ?

Which version of flash loader you are using ? you file you load is a .hex ?

As first root , try to check your power supply if it is under specification.

As primary check , check if you hardware environment is ok :I recommend to run any ready-to-use example in STM32CubeF1.
