dittohead Posted December 3, 2019 Author Posted December 3, 2019 So I remove fbtft_device. But not underdsand how enable DT support for fbtft i add dtoverlay=waveshare35a to nano /boot/armbianEnv.txt and copied waveshare35a.dtbo to /boot/dtb and nothing changes
Igor Posted December 3, 2019 Posted December 3, 2019 On 12/3/2019 at 8:17 AM, dittohead said: armbianEnv.txt Expand Waveshare corporation does not support Armbian and vice versa. DT support for those display does not exists. Somebody has to make overlays. Then it becomes simple.
