1.git clone GitHub - BPI-SINOVOIP/BPI-R4-MT76-OPENWRT-V21.02
-
./scripts/feeds update -a
-
./scripts/feeds install -a
-
make -j1 V=s
then display
In fact, the file is there
This is reported multiple times…
No feeds update / install as it breaks things and the you need old buildchain (ubuntu 18.4). Tried with ubuntu 22 and was not able to compile,u18 was working so far.
R4 is supported by mainline openwrt except rss+lro and the wifi7 card.
1.git clone GitHub - BPI-SINOVOIP/BPI-R4-MT76-OPENWRT-V21.02
- make -j1 V=s
compile environment is on ubuntu -18.04 x64.
you can refer to this file to build the image. https://git01.mediatek.com/plugins/gitiles/openwrt/feeds/mtk-openwrt-feeds/+/refs/heads/master/autobuild_mac80211_release/Release.md
I’ve written some steps and uploaded my build-environment (chroot) here:
Had not got fit images loaded via my uboot because of the size,but was able to build and flash in an ubuntu 18 chroot inside my ubuntu 22 
thanks,default .config can build.
when i enable .config CONFIG_PACKAGE_kmod-mediatek_hnat=y
build error
the error infomation:

Moderated…please use code formatting for better readability
Please don’t enable this compiler flag because it is the proptirtary hnat module to work with mtk proprietary wifi driver.
For open source mt76 wifi driver, it uses flowblock-based hnat instead and is enabled by default.
開源BSP並沒有使用到傳統的nf_hnat module, 而是使用upstream的flowblock hnat架構 預設都已經打開了,不用額外再去開啟nf_hnat, 那是搭配logan driver使用的…
上面是MTK原厂的回复
Do you mean that you do not choose to compile this, but also have the official HNAT ?
Please write in english
Translation by Google:
The open source BSP does not use the traditional nf_hnat module, but uses the upstream flowblock hnat architecture. The default is already turned on, so there is no need to turn on nf_hnat additionally. It is used with the logan driver…
The above is the reply from MTK original factory
Hello, please tell me that the firmware is turned on by default, please tell me: R4 Did he turn on 3 PPE by default? Is the number of connections 32K?
你好, 请问新驱动编译后的固件默認打開了硬件加速,那請問一下: R4 他是默認開了3 個PPE了嗎? 每个PPE的連接數有32K嗎?
Default setting is 3 x PPE with 4K table size.
with 4K table size is too small which file can i modify it?
try to trace mtk_ppe.h, then you can find the answer.
Follow instructions，finally, can only compile *.bin，no img，did i miss something？
It is an openwrt image that can be upgraded by webui.
Hello i am new user to openwrt and bpi-r4. I have a bpi-r4 board. I cloned the source code at
i am following the instructions
./scripts/feeds update -a
but got error
fatal: repository ‘https://git01.mediatek.com/openwrt/feeds/mtkopenwrt-feeds/’ not found
Can someone give me advice. I also created an image from openwrt official site with the same steps and got no error. my ubuntu: 22.04
Do not do this in bpi version this will break things. Only do this on mainline openwrt base.
You will not able to compile this repo with ubuntu22…i only got u18 working…but why using the outdated repo?
kaka, I saw the recommendation to use v.18 above. but I don’t have a computer running that version so I just assumed that the other repository had been removed.
but why using the outdated repo
I don’t understand what you mean which repo is outdated? Should I continue with the official openwrt repository and why? I have a question, why is it only a snapshot?
You refer to GitHub - BPI-SINOVOIP/BPI-R4-OPENWRT-V21.02
To receive updates and have less trouble installing packages.
Openwrt only got 1 stable per year and on last stable r4 support was not ready yet. Between this stable releases new functions are only available in snapshots
If you need support for the wifi and/or rss/lro you are needing the bpi-repo as these are not yet upported to recent versions. If you do not really need these you better use mainline
