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.

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 · Friday at 7:19 AM

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 · Friday at 7:52 AM

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

sakuya06 · 2025-10-19T03:40:05+0100

After updating the dts file, FreeBSD turned into panic mode. patched-v1 contains syscon and grf problem, and patched v2 constains kernel panel after changing compatible = "rockchip,rk3328-grf";

Actually I just need to replace incorrect grf to 0x22 (this address refer to syscon@ff110), and Voila!
The last thing that I need to fix is uboot and speed test ofc. How to prevent this sdcard detected as mmc1 (this will lead to undetectable rootfs) and supposed to be mmc2?

EDIT: the port's led is turned on, but the information remained no carrier. There is some warning about ure0: ure0: timeout waiting for phy to stabilize. A few second later, FreeBSD give up the phy.

why to you load the dtb as an overlay ?
just use the method
mydtb_name="/boot/dtb/rockchip/rk3328-nanopi-r2s-new.dtb"
mydtb_load="YES"
mydtb_type="dtb"
and get rid of the overlays
assuming this rk3328-nanopi-r2s-new.dtb is what i posted
probably the overlay causes phandle mismatches (they should not happen normaly) like grf pointing to the wrong stuff

covacat · 2025-10-19T10:54:18+0100

also does ure0 work in a normal pc ?

adding overlay to loader.conf did not change anything since u-boot already handle it.

these ports work normally in original firmware. my current guess is incorrect dts somewhere nearby ethernet@ff550
