Blank screen with Nucleo STM32F072RB #3164

I've been trying to run the UTFT_demo_fast on my Nucleo F072 with no luck. I'm using a 240 x 240 ST7789 with no Chip Select. It works perfectly well on an ESP32 up to 24MHz. The backlight is on but nothing is shown on the screen. I have tried both SPI ports 1 and 2 as well.

I've tried downgrading the STM32 board package version to 2.6 as #3125 but results are the same.

IDE: Arduino IDE 2.2.1 TFT_eSPI: Version 2.5.34 STM32 Board package version 2.7.1 Processor: STM32F072RBT6 (Nucleo F072) TFT Driver: ST7789 Interface: 4-Wire SPI

The following STM32 processors are supported with optimised drivers: STM32F1xx, STM32F2xx, STM32F4xx, STM32F767

Other STM32 variants should work with the slower ardiuno calls. To try that comment out this line on the setup file:

#define STM32

You will probably need to use the default Arduino SPI pins. Note this is not tested by me!
