I reordered a new pcb with a reset control. It now works 100% of the time!
Thank you for your help!
from lovyangfx.
Bus type: SPI (shared with SD card)
is that behaviour consistent whether there is a sdcard inserted or not?
from lovyangfx.
It is the same even without SD card unfortunately
from lovyangfx.
I also add that the screen is connected via 3-wire spi, so no miso

Sorry to disturb you, but i still have the same problem, i can't figure how to fix it
from lovyangfx.
had another look at the schema, but I can only theorize since I don't have the device:
apparently the display reset pin isn't routed to the esp32, does it rely on power to operate the reset?
what's pin 12 on the display socket?
speculation: if the lcd reset isn't controled by LovyanGFX at init, then the probablility that this problem is caused by something else is higher
it could be worth testing something like this at boot just to see if it changes anything, but with that reset pin attached to 3v3 on the lcd socket I'n not sure it'll have an effect:
hardware::setScreenPower(false);
delay(200);
hardware::setScreenPower(true);

Yes, i thing that's the issue; i ordered a new pcb with a fix. The behavior of the pcb shows that is may be the problem.
Thank you! I will tell you in a week
