Electrical – ILI9486 Display Init FSMC

I have ILI9486 based tft display to initiate via 16bit FSMC. I did gpio, fsmc, and lcd initialization.

Mem. regs:

CMD: 0x60020000
DATA: 0x60000000

Timings:

  Timing.AddressSetupTime = 2;
  Timing.AddressHoldTime = 0;
  Timing.DataSetupTime = 5;
  Timing.BusTurnAroundDuration = 0;
  Timing.CLKDivision = 0;
  Timing.DataLatency = 0;

Wiring is double checked. NE1 is CS, RS -> A16, Reset set high.

The problem is that the display seems to be ON after all (gray background), but it's not possible to draw anything on it.
Practically, doing DRAW_SOMETHING(…) the display just flashes and turns bright gray. I have checked every command and absolutely have no clue why this could happen.
Any help highly appreciated
thanks ~

correct memory addresses:
