Hi, I have made some changes to the dts, can you have a look? Maybe they can be added in the next version. https://github.com/openwrt/openwrt/pull/15936 Best regards, Shengyu 在 2024/6/2 18:40, Chukun Pan 写道: > The Bananapi BPI-R3 mini is a development board with the > MediaTek MT7986A (Filogic 830) SoC. > > Key Features: > 2GB DDR4 RAM > 8GB eMMC flash > 128MB Nand flash > MT7976C DBDC WiFi > 1x FAN connector > 1x NANO SIM slot > 1x USB2.0 Type-A > 1x M.2 Key B USB > 1x M.2 Key M PCIe > 2x 2.5GbE EN8811H Ethernet > Type-C PD 12V Power supply > > Signed-off-by: Chukun Pan <amadeus@jmu.edu.cn> > --- > arch/arm64/boot/dts/mediatek/Makefile | 1 + > .../mediatek/mt7986a-bananapi-bpi-r3-mini.dts | 480 ++++++++++++++++++ > 2 files changed, 481 insertions(+) > create mode 100644 arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3-mini.dts > > diff --git a/arch/arm64/boot/dts/mediatek/Makefile b/arch/arm64/boot/dts/mediatek/Makefile > index 37b4ca3a87c9..14af5681d0ee 100644 > --- a/arch/arm64/boot/dts/mediatek/Makefile > +++ b/arch/arm64/boot/dts/mediatek/Makefile > @@ -12,6 +12,7 @@ dtb-$(CONFIG_ARCH_MEDIATEK) += mt7981b-xiaomi-ax3000t.dtb > dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-acelink-ew-7886cax.dtb > dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3.dtb > dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-emmc.dtbo > +dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-mini.dtb > dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-nand.dtbo > dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-nor.dtbo > dtb-$(CONFIG_ARCH_MEDIATEK) += mt7986a-bananapi-bpi-r3-sd.dtbo > diff --git a/arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3-mini.dts b/arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3-mini.dts > new file mode 100644 > index 000000000000..683b7394ff79 > --- /dev/null > +++ b/arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3-mini.dts > @@ -0,0 +1,480 @@ > +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT > + > +/dts-v1/;
