Thank you! I can already test using @sinovoip 's image then, It hopefully tells me whether my key m → minipcie adapter has the pcie pins actually connected, or only the usb pins. Let me know whether there’s something else I should test!
I’m using openwrt master with dangowrt’s bpi-r4 branch mergef
So I tested using the img file on the wiki, the link is not coming up, I think the adapter is not forwarding the pcie link, I’ll order myself another one
@dangowrt: congrats on getting the BPI-R4 upstreamed! I re-built the upstreamed openwrt, but right now I get this error during startup:
[ 1.724181] mtk-xsphy usb-phy@11e10000: incompatible phy type
[ 1.730017] mtk-pcie 11280000.pcie: failed to get max link width
[ 1.943471] mtk-pcie 11280000.pcie: PCIe link down, ltssm reg val: 0x1
[ 1.950120] mtk-pcie: probe of 11280000.pcie failed with error -110
Are you sure the issue isn’t at the driver? It looks like the mtk-xsphy isn’t accepting the phy, no?
EDIT: forget about this, I wasn’t booting the correct image and ended up with prebuilt image on sdcard, sorry
How did you compile the @sinovoip github openwrt image? The image on the wiki doesn’t work, and defconfig → build sdcard of the github branch for bpi-r4 results in a compile error while building the kernel
Here is written that compile works with ubuntu 20.4
Which os do you use for building?
I guess newer gcc does not work because of additional checks. You can try using oldest gcc you have on your current system…ubuntu has different versions you can install
I’m building using gentoo. Here’s something about the build system:

Is your crosscompiler (aarch64-linux-gnu-gcc) also v12? Maybe you can try lower version (i guess around 9 should work).
How does the system cross-compiler get involved when the openwrt is using musl? EDIT: and yes, using 13, actually
ah, you’re right, openwrt first compiles his own crosscompiler, forgot this.

Exactly. I also took a look at the failing makefile, It looks like this:
# The filename Kbuild has precedence over Makefile
kbuild-dir := $(if $(filter /%,$(src)),$(src),$(srctree)/$(src))
kbuild-file := $(if $(wildcard $(kbuild-dir)/Kbuild),$(kbuild-dir)/Kbuild,$(kbuild-dir)/Makefile)
So it looks like the variable kbuild-dir isn’t initialized properly, leading to a
/scripts/basic/Makefile
call, whereas
./scripts/basic/Makefile
would actually work. Nonetherless, when compiling the kernel, it should already use the openwrt compiler @sinovoip1 @sinovoip : any suggestions?
The pcie2 does not yet work with mainline openwrt,so it is a bit different case in this thread.
Also, as far as the issue with the makefile you’re running into. As soon as I switched to ubuntu 20.04 AND was using 5.4 kernel, that error went away. Even if you correct the Makefile you run into more errors later. The system you’re building on is too new.
Yes, by default, I’m using openwrt master branch, But I’d like to check whether my key b → key e adapter works for pcie. No doubt it will work after some time on openwrt/master, but I’d like to check first. I’ll create a ubuntu vm and build it on that one
so I created a ubuntu 20.04 server vm, installed necessary packages, ran make defconfig, menuconfig → select BPI-R4 SD, enable target specific packages, but I still do not succeed at building a minimal openwrt distro Has anyone a (minimal) binary SD card image which I could use? the only thing it really needs is lspci and dmesg (or busybox for all I care)
I can build you an image. Do you want me to use the bpi github or the master branch? What packages do you need?
This one:
I need an sdcard image for bpi R4, with target defaults, pci-utils and pciids, that’s all, actually (but usb-utils and usbids would also be nice)
Thx. I sent you access request
Maybe you can make this file/folder public? This lets others use the image too and help getting this pcie working?
