Display initialization does not work in this configuration. The problem is only in this HW configuration and in the TFT_eSPI library. Everything works when I using the Adafruit_ST7735 library. If I replace the STM32F103 with the RB2040, the display with the TFT_eSPI library also works.
Combination STM32 MCU based board 2.7.1 + TFT_eSPI 2.5.43 nor a combination STM32 MCU based board 2.6.0 + TFT_eSPI 2.5.43 doesn't work. The result is the same. :-(
