We are using this ic STM32F103VET6 and Oscillation of 8 MHz Crystal with through capacitor of 22pf i am not getting the Oscillation from the microcontroller ?

We have two same design Board, one is fabricated in last year, another one is this year fabricated boards and i loaded same code for both boards.

Achivally this year what i fabricated with little changes on the Connector side and we are used buffer ic for UART communication issue for TX and RX side.

Same microcontroller, Same code,same all components.

May i know what is the Problem ?

Maybe the crystal is not exactly the same after all. Try different (smaller) capacitors.

look into crystal oscillator datasheet. Look for load capacitance value !
