Hello everyone,I designed my own board which partly failed.I used 32768 Hz ceramic crystal for LSE and 8MHz ceramic resonator for HSE.I can upload my code successfully, but, it doesn't execute unless I disable both LSE and HSE.I'm not professional de...

Hi everyone,I'm designing my first STM32 design using STM32F103C8and wondering if I can use 2 Ceramic resonators instead of oscillators as shown in my schematic.thanks in advanced!Tommy

SOLVED!Great thanks to TDK and his advice. Replacing Y41 with 3.3 K solved the problem.It's sure any another value around 3.3 K should work also as long as the HSE current is around 1mA.

Thank you for taking your time reading my question!Maybe you're right because all the documentation which I read says nothing about the R ext resistor (which in my case is R41).The only thing which mentions it is the HSE current. With some calculatio...
