Manta E3EZ CB1 dual display BTT TFT35SPI and HDMI7 touch dont work at the same time #26

Hi!

I have a problem how to figure out that both screens work at the same time. I am moving from MARLIN to KLIPPER with my new Manta E3EZ CB1 and dual screens BTT TFT35SPI and HDMI 7 touch. I can run only one screen at the same time... Any help will be appreciated.

Same problem here. If i use the file "sun50i-h616-biqu.dtb" instead of the standard -sd version in the bootenv.txt, my HDMI display shows only a small red Klipper Icon but nothing else. Using the original file my 3.5 spi TFT works just fine. I want to use both.

I am using a non emmc CB1 with Manta4 board, BTT 2.4 SPI TFT with IO2CAN Extension and external standard HDMI device externally (USB single atm.) If you need logs or config i can provide them.
