Hi, I am starting to use the new SOM-RK3399v2 Dev Kit with a buildroot distribution (this is Ubuntu group, i know, but there is no buildroot group yet) I observe latency issues (> 2ms) with its default kernel (4.4.179, branch remotes/origin/nanopi4-linux-v4.4.y) Furthermore I observe spinlock lockup...

Hi,

I would like to use a mipi dsi panel for my SOM-RK339 board as default (or secondary) screen.
Can anybody advise me what I need to do in device-tree, u-boot and kernel ?

Best regards,
mb

Hi,
I would like to use a kernel with a CONFIG_PREEMPT_RT patch on RK3399.
Is it possible ?
Anyone made experience with it ?
Best regards,
Markus
