Description Peter Robinson 2025-10-17 17:40:36 UTC

It may be that a recent update broke display output on rk3399 devices.

Not sure if this is all displays, all devices, or just HDMI on rockpro64

Reproducible: Always

Comment 1 Nikita Shvets 2026-06-10 18:02:20 UTC

On the NanoPC-T4, the display works (at least with the U-Boot 2026.04 build and Dell DP3017) but neither Fedora Everything 44 nor Fedora Workstation 44 boots.
On the ROC-PC-RK3399, there is only a black screen after GRUB2 (regardless of uboot version - Tow-Boot build, LibreTech build, Fedora build).

Do you happen to have either of these two SBCs? What is your observations with 44 iso and uboot 2026.04 on ROCKPro64?

Comment 2 Peter Robinson 2026-06-11 13:30:15 UTC

It boots for me on a rock960 and a pinebookpro, please file a new bug, don't hijack this one.

This ended up being a non problem.
