Need help running FreeBSD aarch64 on Nanopi R2S-Plus

status = "disabled";
you need to edit it and change it to okay / or remove the status prop

covacat · Wednesday at 8:25 AM

do
dtc -I dtb file.dtb >file.dts
edit it with your fav text editor
dtc -I dts file.dts >file.dtb
copy it over the original and you are done

aaah, the one I have compiled from friendlyelec source only has ethernet@ff540000. definitely missing ethernet@ff550000

sakuya06 · Wednesday at 10:26 AM

tbh, I do not what to copy. The only working dts is from friendlyelec source code. The generated dtb is different from the most recent uboot.

covacat · Wednesday at 10:39 AM

here is a dts file pulled from u-boot (2025-04)
compile it to dtb and put it in /boot/dtb/rockchip/test.dtb
then in loader.conf put this

mydtb_name="/boot/dtb/rockchip/test.dtb"
mydtb_load="YES"
mydtb_type="dtb"

reboot
see what you get

LE. enable the second gmac first cause it's disabled now

This place has good stuff including a u-boot.

thank you for helping me modifying the dts file. I will report back once I tested the dtb

This is how I do a temp fix too.

Use DTC compiler to decompile active dtb file to a dts file (backup original first). Then use editor to fixup dts file and save out. Then recompile to dtb. Reboot.

Little primer on another platform.

Modifying the device tree for the Beaglebone Black

I have used Yocto to create a small linux image for the Beaglebone Black. I think I have most everything working like I want it, except I need access to UARTs 2 and 4. When I was using the standard

After verifying my temp fix works I build a desktop overlay for the fix.
That way you can upgrade without worrying about original dtb being overwrote during upgrade.

this file behave similar with official u-boot. it is stuck at clock problem.

Good news! I am almost there, just need correcting syscon and grf driver handle. Bad news, I do not posses full knowledge about this. I just copying what make sense in armbian.dts.

covacat · 2025-10-17T07:19:56+0100

can you attach the whole dmesg / kernel boot messages ?
both gmacs use the same grf node so its weird the first gets it an 2nd doesnt

covacat · 2025-10-17T07:52:33+0100

i think i have an idea
somehow the simple-mfd driver loads instead the rk-grf driver
edit the dts and at syscon@ff100000
change compatible = "rockchip,rk3328-grf\0syscon\0simple-mfd";
to compatible = "rockchip,rk3328-grf";
rebuild the dtb and reboot

I forgot to bring it with me this weekend.

I will try this solution tomorrow, and report back with complete dmesg
