After the OS writes to the SD card, there is a FAT32 partition named BOOT, open "BoardEnv.txt" file with Notpad, Notpad++ or VSCode.

Uncomment overlays=tft35_spi to enable TFT35 SPI screen (Delete '#' at the beginning of the line).

NOTE: If the OS image of v2.2.1 version is used. Set to overlays=tft35_spi25 instead of overlays=tft35_spi Use the SPI speed of 25Mhz instead of the default 50Mhz to avoid display confusion. If the OS image after V2.2.1 is used, The OS will use a lower and more stable speed by default.
