OPi Zero spi tft problem

waylander

        Hello all,

        i've enabled spi and seems like it is working and even recognizing my tft, but it remains uninitialized (i see only white color).
        here is the log https://pastebin.com/iH1XuZB0
        can someone say why log seems fine, but nothing is happening?


i was following instructions from this topic:

Did you install corresponding driver of the tft? I am not sure whether it is the problem of driver.

do you mean name parameter of fbtft_device? yeah, i've tried several options, but none worked. in log, however, it is showing that tft is ok.

Hi, dear waylander. I haв some problem, in my case:
1. Install Armbian_5.35_Orangepizero_Ubuntu_xenial_default_3.4.113 (Very important Unbuntu, not Debian.)
    because Unbunta have driver for LCD from the box.
2. Now you must will know what chip used your LCD in my case ili9486. (My LCD)
    Very important knows what chip you use!!! If you will wrong then LCD do not worked.
3. type in consile :  sudo modprobe fbtft_device custom name=fb_ili9486 gpios=dc:18,reset:2 speed=16000000 busnum=1 rotate=90
4. and type : sudo con2fbmap 1 8
