Sming - Open Source framework for high efficiency native ESP8266 development

#62010 I had a Sming based program that controlled a 1.8 TFT screen through SPI with no issues.

But I've upgraded to the latest Sming repository version (both master and develop show the same issue) and now the screen doesn't initialize.

Without changing any hardware, flashing again the old version makes the screen working again.

Also flashing the code ported to the ESP8266 Arduino, also works fine.

So the issue is definitely with the Sming SPI driver.

Even the provided ST7735 Sming example doesn't work.

Any ideas?
