Hi!

 

When I try to run overlays on Armbian 21.08.2 Focal, they do not seem to load, see attached screenshot below for the output during boot. It looks to me that fdt is not properly run or sth.

 

root@rockpro64:/boot# cat /etc/os-release 
NAME="Ubuntu"
VERSION="20.04.3 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Armbian 21.08.2 Focal"
VERSION_ID="20.04"

 

root@rockpro64:/boot# cat armbianEnv.txt
verbosity=1
bootlogo=false
overlay_prefix=rockchip
rootdev=UUID=73fac48d-4f73-4ac1-b899-e67dc98b5794

extraargs=net.ifnames=0 isolcpus=4,5
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u
 

Anyone seen this before and knows what the issue can be/how it can be solved?

 

Thanks in advance!

 

I found the same issue on my RockPro64 running on Noble, kernel 6.6.63-current-rockchip64. I tried different kernels and gave armbian-config a chance to recreate the line in armbianEnv.txt related to overlays, but it did not improve. As a result of this problem, my board cannot go over 1800Mhz.

But 2 different boards, Asus Tinkerboard-2S, with the same SoC, one Debian second Ubuntu runs on 2GHz fine.

I will try to edit dts file to get what I want I think.

Merged content of overlay file into main dtb file; rebooted and whoa... I rockpro64 jumped to 2GHz.

 

Overlay:

/dts-v1/;

/ {
        compatible = "rockchip,rk3399";

        fragment@0 {
                target-path = "/opp-table-0";

                __overlay__ {

                        opp06 {
                                opp-hz = <0x00 0x5a1f4a00>;
                                opp-microvolt = <0x124f80>;
                        };
                };
        };

        fragment@1 {
                target-path = "/opp-table-1";

                __overlay__ {

                        opp08 {
                                opp-hz = <0x00 0x7829b800>;
                                opp-microvolt = <0x13d620>;
                        };
                };
        };
};

 

Commands required to edit the main dts file:

sudo apt install -y device-tree-compiler
mv rk3399-rockpro64.dtb rk3399-rockpro64.dtb.orig -v
dtc -I dtb -O dts rk3399-rockpro64.dtb.orig -o rk3399-rockpro64.dts
nano rk3399-rockpro64.dts
dtc -I dts -O dtb rk3399-rockpro64.dts -o rk3399-rockpro64.dtb
reboot

I am suspicious that the SBC was overheating and that it was refusing to stay on 2GHz and rather dropped to a lower frequency of 1.8GHz.
