BPI R2 LEDE(openwrt) source code

I guess your device tree (mt7623.dtsi) was wrong. Please check https://patchwork.kernel.org/patch/9958277/

num-lanes = <1>;

I use your submitted patch. Kernel boots fine but hangs at the following point:

Same problem: does not match pci header type 01 and hangs on “bridge configuration invalid”.

If gary’s image cannot work on your board, i guess it should a board issue. That’s why it still hang at pcie part after apply many patches, thanks.

Garry’s 4.4.70 Kernel works fine and PCIe too. I am wondering that garry’s kernel uses mt2701 for PCIe obn BPI-R2 but the Devicetree for BPI-R2 include mt7623 in Kernel 4.9.44 and then PCIe initialization fails.

Can you explain this fact please?

@garywang: can you upload the mt2701 PCIe devicetree please?

@garywang Hi ,i got problem with latest lede i got error

I assume there is a problem wtih uboot-mtk-bpi-r2 package but i cannot get it built.

I have same problem. It just abort before build image of SD card. But the uImage-mt7623n-bananapi-bpi-r2 and root.squashfs has been build in ./build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32. So you can just use that two file and flush it into your R2 board follow this:

btw. Do you update the feeds after 2018/1/1? Another preblem is libuci-lua (>= 2018-01-01). You need download the Makefile and uci.sh in lesource/package/system/uci at master · lede-project/source · GitHub and replace same file in ./package/system/uci.

Or maybe update code please, garywang. :wink:

@BoringCat yes , i just changed by hand package version in Makefile of uci and it works :slight_smile:

I know method with TFTP but i seen that is option to buld SD card ready image so i tried it and it fail.

Sorry, I’m trying to bundle preloader/uboot/kernel/rootfs as an image, but this feature isn’t done yet, please use the code based on previous commit.

Sorry for this.


hi i did all the step at the first post but the systen hyng at boot, the last what i see is

on my build system i did:

git clone https://github.com/garywangcn/bpi-r2_lede.git cd bpi-r2_lede

./scripts/feeds update -a ./scripts/feeds install -a

cp …/config ( the attached config from the first post ) ./.config make menuconfig -> exit -> did the save

make after a while the the complie proccess is finished without error then cd build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32 scp root.squashfs uImage-mt7623n-bananapi-bpi-r2* [email protected]erver:/tftproot

then on the bpi-r2 the step with the uImage-mt7623n-bananapi-bpi-r2.initramfs ( see below at the quote )

please help


@mark05 did you change branch? you need to

git checkout bpi-r2-on-lede-v1

after you clone

@garywang i build the latest version flashed mtk-bpi-r2-SD.img to SD Card and i got error

even if i update uboot package to latest commit.

Hi Pkalemba

Please don’t use the mtk-bpi-r2-SD.img, we are trying to bundle preloader/uboot/kernel/root file system as an image, but it’s not ready. Sorry for this.


i did an fresh clone

but there ist no branch bpi-r2-on-lede-v1


strange online there is that branch…have you defined any options for git to get only the master branch?

Garys repo has newer code…

hi there are no options set at git , it is a fresh install debian ( devuan ) system just for bpi r2 source code compile

ithe is no .git at all.

in my browser i see the diffrent branch bt i i do the git clone with https i get only the master branch

so [update]

i did an

git branch -a ( got )

i start the make




make fails with

as gary said: do not use mtk-bpi-r2-preloader-sd.bin…

you can try to move back with

git checkout commit-id


e.g. using 51b0bac as commit-id

hi thanks for help

please be sorry for my missing knowledge about git .

i have to learn … about git and the bpi-r2



kernel build susccessful an bpi-r2 boots him but i miss the wifi interface.


Iassume you must start wifi driver with wmt-tools like in debian/ubuntu.

Please use the latest code, thanks.
