Arduino for STM32

Hello,
I am trying to develop bootloader by using this https://github.com/darkspr1te/stm32f107vc_sd_bootloader it works fine but I am using roger clark's library for arduino ide i.e. https://github.com/rogerclarkmelbourne/Arduino_STM32 .
Now the problem is this library works for vector table address ...

yeah its came by keeping
SPI.setMISO(PB14);
SPI.setMOSI(PB15);
SPI.setSCLK(PB13);
SPI.setSSEL(PB12);
in setup()
but printing is very slow when compare with my old core.
see graphics test code run resultswith this core

hello .rpv
blink ok, Serial ok but SPI not working.
i am trying to run graphics test code from adafruit its compiling but not able to get anything on display.
I kept like this.

#define TFT_MISO PB14
#define TFT_MOSI PB15
#define TFT_CLK PB13
#define TFT_CS PB12
#define TFT_DC PD9
#define TFT_RST ...

Thank you @.rpv

Hello,
At present Im working STM32f103vet6 on roger's core https://github.com/rogerclarkmelbourne/Arduino_STM32
now I want to use https://github.com/stm32duino/Arduino_Core_STM32 this core.
In this core I can not find VET6 controller. Is that controller core is developing

as we already discussed in github, you can refer that topic for more details
