Trouble building from source (mtk sdk)

Banana Pi Router design BPI-R4(MT7988)
1

I have successfully built an image from source. I only included Luci as an extra with the argon theme. I used the directions from here: https://git01.mediatek.com/plugins/gitiles/openwrt/feeds/mtk-openwrt-feeds/

I initially had errors complaining about: openwrt/build_dir/…/linux-6.6.86/arch/arm64/boot/dts/mediatek//mt7988a-rfb-eth0-gsw.dtso: No such file or directory.

I then found those files in my other git folders and copied them where the build process was looking for them and the build completed.

Now when I boot that image it seems to work and I get the openwrt prompt using a serial connection but I can not connect over any wired connections. Over serial the system seems to work fine.

where should I look next or did I mess up my build by manually coping the files?

it doesn’t look like the network drivers are loading. They dont even show up in the make menuconfig. I even started a fresh git pull of openwrt without the mtk feeds and the drivers dont show up under Kernel modules → Network Devices

Is there a step I am missing?

@frank-w can you post your openwrt build link. I am having trouble finding it. I thought I saw some beta openwrt builds you had sdcard images available for download.

you should research the mtk network driver, Maybe you need modify the special board’s device tree files.

I am also failing at that step

mt7988a-rfb-eth0-gsw.dtso: No such file or directory.

From where did you get the file? I can’t seem to compile it

I would search this file without extension using “grep -Rni mt7988a-rfb-eth0-gsw .” In the sourcedir and disable it in the Makefile. R4 is supported in mainline openwrt and you should select it in make menuconfig. So this file is not needed for final image.have not found it by searching in the git repos to identify the patch addding the entry in makefile.
