I soldered my Circuit Sword Lite and have an issue. Display blinks and I can hear tick sound on every blink. Frequency of blinking is increasing with time. Touching BL_ON area stops blinking for some seconds, the area is very hot. Any suggestions? https://drive.google.com/file/d/1xmyilV99QW30bBFzqr5...

Oh so you couldn't get it to work on the breakout board but could on the bare screen?

yes

Thanks for posting this, Ive tried out your commands but with a screen on a breakout board like this one https://www.aliexpress.com/item/1-3-Inch-IPS-OLED-Display-Module-240-240-RGB-TFT-for-Arduino-DIY-LCD-Board/32880670572.html?spm=2114.search0104.3.16.693374747K6Ddc&ws_ab_test=searchweb0_0,search...

I have DC pin, I don't have CS pin Hey I know this is a old post but did anyone get the 1.3" st7789v screen working, I'm really struggling.

Ah ok, not the screen I thought it was.

Can you probe the ribbon and the pins to prove the PCB is correct?

yeah, already did this, seems to be ok. maybe smth wrong with a driver I'm using
but I saw this image on aliexpress

If it's the screen I think it is, the silkscreen is wrong! Try RPI Display 3,3V(Pin1) VCC Ground(Pin6) GND MOSI(12,Pin19) SDA n/a SCK CE0(10,Pin24) CS SCLK(14,Pin23) A0 25(Pin37) RESET Then your modprobe line should get you something. The built in driver has the colours flipped, but we can fix that...

Ah ok, maybe you need the v then. Have you checked dmesg to see if it's actually loading the driver first? yeah, driver is loading according to dmesg, but actually only black screen with backlight on display all the time, fb0 & fb1 are listed in /dev. con2fbmap does nothing. probably smth is missing
