Nice work. The tree can enjoy more benefits from upstream effort from mediatek. MediaTek have already posted VLAN support on MT7530 on the internet. You can try it. https://lkml.org/lkml/2017/12/7/39
mmc is fixed in my repo too 
i’ll take a look on vlan-support, maybe make a separate branch for testing it

vlan.diff (16,0 KB)
merged master into vlan_support-branch…compiles fine
uploaded compiled kernel from main and wifi-branch here: https://drive.google.com/drive/folders/1EGN1TvqCpDHdOAS-mjRg9ipi0kahnOUV for testing
for wifi, same steps as with 4.4.70 have to be done: https://github.com/BPI-SINOVOIP/BPI-R2-bsp/tree/master/vendor/mediatek/connectivity
for vlan…have any kernel-option to be set for testing? enabled some vlan-option, i think which are needed/meaningful…
IPVLAN=m
MACVLAN=m
NETFILTER=y
NET_L3_MASTER_DEV=y
BRIDGE_VLAN_FILTERING=y
IP_NF_IPTABLES=m
IP6_NF_IPTABLES=many idea how to get uart1 working? did the same steps as for uart0 (status=okay in bananapi.dts), but it is not recognized by system
root@bpi-r2:/sys/devices/platform/11003000.serial# ls of_node
clock-names compatible name pinctrl-names status
clocks interrupts pinctrl-0 reg
root@bpi-r2:/sys/devices/platform/11003000.serial# cat of_node/status
okay
to compare with uart0 (here a folder “driver” and “tty” exists):
root@bpi-r2:/sys/devices/platform/11003000.serial# ls
driver_override modalias of_node power subsystem uevent
root@bpi-r2:/sys/devices/platform/11003000.serial# ls ../11002000.serial/
driver driver_override modalias of_node power subsystem tty uevent
send does also not work ;(
Wifi-branch is merged to main,uart is working Cryptodev is also included (must be compiled separately).
There are 2 minor issues with wifi,see that thread: R2 internal Wifi/BT (MT6625L) - Kernel 4.14.x/4.16
Hnat compiles fine in separate branch, vlan is only compiling with 4.15 base,i try with 4.14 but stuck in modified function Vlan-support backporting to 4.14

any idea which options are missing to get HDMI working? comparing currently with 4.4…
tried to add DRM drivers and dts-nodes from 4.4, but still not working, instead kernel does not load 
We will add HDMI support in the future.
Is there any timeplan? Please make it compatible for 4.14 if including in mainline
opened an issue on my github-repo (hdmi-branch):
We will send patches during v4.16
anything new?
is there a chance to get a stable wifi-driver for internal wifi (mt6625l) without the wmt-tools?

is anybody working on a wifi-driver for mt6625l? currently i try to port existing driver to 4.16, but it’s not easy (for me) and this will not fix the problems of this driver
Hi folks. I try to build kernel for my Banana Pi R2, because I need specific WiFi NIC. So I CrossCompiled kernel uBoot, install uBoot image on microSD card. Finally no boot. No display. So I am searching for instructions, I try what I found on that thread, same issue. Do you have some references or docs?
Thanks everyone.
Which kernel do you use?
Here are instructions for manually install OS:

Thanks answer, I try to build 4.4.70, same as I found on Image from Google Drive. The propos is I need to add module for another WiFi NIC because the build-in one is not enough to made an AP.
So I tryed that : http://wiki.lemaker.org/BananaPro/Pi:Building_u-boot,_script.bin_and_linux-kernel, without success on building u-boot and BSP.
I think this uBoot is my issue.
I’ll try instruction.
I success
Do you use an existing image and replace uboot/kernel or do you start with empty sd-card? Have you pressed power-button at least 10 seconds? You look on debug-uart?
I use this image 2018-03-29-ubuntu-16.04-mate-desktop-bpi-r2-sd-emmc.img I whiped first parttion (sdb1) and rewrite U-Boot and first partition ot boot my new kernel.
Following this instructions: http://www.rvq.fr/linux/bananapi.php
and also instructions I found on current thread. No success.
this instruction uses uboot from git.denx.de…this does not have drivers for chipset included. The defconfig is for bananapi (m1).
You have to add drivers at least for mt7623 to thus uboot source or compile it from official bananapi-r2 repo.
I also wanted a newer uboot,but have not figured out how to add the drivers
why do you want to replace uboot? You can replace kernel without changing uboot…uboot needs only to be replaced if itself is changed
Regarding kernel itself your instructions is also not usable because of the wrong device. Here you can use my repo and building with build.sh
hdmi on mt7623 seems already in upstream one moment ago

I assume this patchset is for 4.17 and needs additional to these 7 patches
There is a patchset with 10 patches and an incomplete one with 24parts
