Hi,
I see that Jetpck5.0.1 DP uses kernel_tegra194-p3668-0000-p3509-0000.dtb.
Theoretically tegra194-p3668-all-p3509-0000.dtb also works, and I used it for previous Jetpack versions.
However, in Jetpck 5.0.1 DP, when I try to use tegra194-p3668-all-p3509-0000.dtb, it causes the system to fail to start.
