STM32F103RB and Totem Pole drive problem

Hi

I am trying to drive the output from pin PA8 (needed because I use it for TIM1 PWM) from 3.3V to 5V using an external totem pole drive circuit. Problem is no matter what I do the voltage of the output signal after the drive stage stays 3.3V.

Is this possibly internal pull up or pull down resistors causing this issue?

Thank you
