Posted on December 12, 2015 at 18:42Hi there,I am using a STM32F030C6 behind a buck stepping down a voltage to 5,5V, then a LDO regulating to 5V and finaly a LDO to regulate a 3,3V for the STM.At the scope, the 3,3V is almost clean. Still having som...

Posted on December 13, 2015 at 17:34I have all the bulk capacitances recommended on the STM32, and I tripled the value of capacitances of LDO. These capa can't be closer to their components.I actually measure on the VDD and VDDA pin and I only have ...

Posted on December 13, 2015 at 12:27I manage to scope the NRST signal. I effectively have very short falling edges (<5Âµs). These falling edges are sync with spikes (80mV) on the 3,3V. My scope is very simple, I may not see that the spike are higher...

Posted on December 13, 2015 at 12:05Hi,It would make sense that it comes from a Flash problem (it would at least explain why a Hardfault is trigger). Could you detail how to set the flash latency correctly?Thank you

Posted on December 13, 2015 at 10:44Hi,Thank you for quick reply.I know it because I have a UART connected to it with a trace on exception that says that the program stops on a hardfault.The program is only a blink led. The led turns on and is toggl...
