Anyone using a BTT Pi TFT43 V2.0?

If you happen to be using the CM4 in an adapter board,  here are the instruction to install the dt-blob.bin driver.  Don't install it if your not using a CM4, as the dt-blob.bin driver disables your HDMI output.

 

Run each of these commands, in order, one at a time:

 

 

wget https://www.waveshare.com/w/upload/7/75/CM4_dt_blob_Source.zip

unzip -o CM4_dt_blob_Source.zip -d ./CM4_dt_blob_Source

sudo chmod 777 -R CM4_dt_blob_Source cd CM4_dt_blob_Source/

sudo dtc -I dts -O dtb -o /boot/dt-blob.bin dt-blob-disp1-double_cam.dts

So disabling the #start_x=1 service reverted the display back to showing only the console, no klipperscreen.  

I don't think I am using the CM4 adapter board.  Just a pi 3B and the BTT pi tft43 screen connected with the DSI ribbon.

If you havn't already,  re enable the start_x=1 service

Then go go into raspi-config, interface options and enable spi and i2c.  Then reboot.

if that doesn't work, im out of ideas.

 

On mine,  untill i have enabled spi and i2c,  i get the same as you.  basically, it displays but touch doesn't work.

I'll try enabling the spi and i2c tomorrow.  I've done so much today, I can't remember If I did that this time around or not.

Also, if enabling spi and i2c doesn't help,  read through Burmans post, here.  His Pi tft50 should be nearly identical.

Thanks for all the guidance!  I ended up using a pi 4 to get it to work.  There must be an issue with compatibility with the pi3's.
