custom kernel - rockpro64

[rocksa]

Hello.

I start this thread here because in not start it in 3399 forum section.

I wanted preempt-rt kernel for my armbian rockpro64 so i have compiled and generated preempt-rt 4.4.167 deb kernel package.

I have installed my custom kernel deb package but after reboot the system boot in old kernel not the custom kernel.

How i can set the system to boot from custom installed kernel ?(4.4.167-rt176 is my custom kernel)

s# ls -a /boot
.                               boot.cmd                   dtb-4.4.174-rockchip64         System.map-4.4.174-rockchip64
