Hi Sir/Mam,
                  Basically we are using the stm32f303VCT6 mcu as our main controller. It takes the gps co-ordinates of the moving vehicle from the on board gps module and then computes some algorithm on co-ordinate as well as some of our internal data and let us know about the position and vicinity of the silence zones nearby our car. Now my issue is whenever i try to run my whole unit during daytime it gets hangs very fast, whereas during the evening time especially when there is no sunlight it performs perfectly as it should.
                      Just for you information i am in india and keeping my unit on the dash board of the car which gerally get somewhat heated, i suspect is the reason for my mcu to get hang?. If yes then can anyone suggest me how can i resolve the issue. Also going by the datasheet of the mcu it says the temperature range of about -40 to 85 degree Celsius.
Any help would be highly appreciated, thanks
