Hello, I am doing AGL (Automotive Grade Linux) porting on Jetson-TX1.
However, the DRM module could not be found.
I tried to find DRM on Ubuntu pre-installed on Jetson-TX1, but DRM did not exist.
I am using Yocto Layer and Add Unofficial ( I don’t know exactly ) TX1 Layer ( GitHub - OE4T/meta-tegra: BSP layer for NVIDIA Jetson platforms, based on L4T )
and I enabled ‘drm’ through ‘make menuconfig’
But loading Failed.How can I enable DRM?
The Log said, “no drm device found”
This is My Log. ( Launch AGL , AGL use Wayland)
