Problem with conneting S64128K through SPI interface to STM32 MCU

Hi,
I'm trying to connect S64128K display through its SPI interface to a STM32 MCU and not getting anything on display.
I have the display connected per attached diagram based on what you provided on your web site and all the caps are 1uF ceramics.
The code for initializing and setting all points on is as below.
I set different CPOL and CPHA on SPI connecting and none of them worked
I was wondering how can I check if the internal voltage booster is working? (there is no 9V on Vout pin)
