Hello, I hope you don't have any problem. Maybe me and my brother have defective or more unstable helios64 than you. Only thing I can say that Prahal share here the specifics files rk3399-kobol-helios64.dtb-6.XX.xx-L2-hs400-opp in this forum since two years ago my helios64 and my brother's helios64 work stable only with it. I back to 6.12.58 Kernel with rk3399-kobol-helios64.dtb-6.12.xx-L2-hs400-opp file and freeze firmware/kernel with armbian-config.

I am having issues with eMMC detection… The kernel does not detect the eMMC, but apparently U-Boot does. Attached are images.

Hi @Edmilson Santos, what about Ethernet?

While waiting for new info, first poke in the dark. rk3399-fix-pci-phy.patch disabled https://testing.armbian.de/r4s/ feel free to test

Perhaps a hardware defect? At least that would be my guess from what it sounds.
