Robin TFT35 V1.0 screen orientation during the boot

[ostapoff]

I am running the Robin Nano V1.2 + Robin TFT35 V1.0 screen shipped with the Sapphire Plus 3D printer. The screen orientation is upside down which is configured by setting the following option: #define TFT_ROTATION TFT_ROTATE_180

The screen works fine when booted but during the boot I can see the "Booting..." or "TFT Updating..." phrases up side down. On native Sapphire Plus firmware it is corrected with this robin_nano35_cfg.txt option:

cfg_screen_overturn_180 0xEE

How can this be configured in Marlin 2.0 with defines?

In marlin you only need to define: #define TFT_ROTATION TFT_ROTATE_180 Then after updating the firmware for the first time, reboot, so that the interface of boot and homepage will be flipped 180 degrees

That's the problem. The interface of the homepage and the booted Marlin is displayed OK but the boot interface is not.

You may see how it works here: https://youtu.be/DY2-9FK_Ue4 On 3rd second the Booting… message appears for a fraction of a second upside down
