BPI-R3 如何支持Nand下可以使用TF卡

〖香蕉派BPI-R4/BPI-R3 Mini/BPI-R3/BPI-R64/BPI-R2 路由器〗

使用目前的固件或者openwrt下载23.05固件，均无法在Nand启动的OpenWRT下使用TF卡，
如何配置和操作才能使用TF卡？

2

默认Nor和Nand启动后， 唯一的MMC控制器接到EMMC。需要改DTS。

&mmc0 {
        pinctrl-names = "default", "state_uhs";
        pinctrl-0 = <&mmc0_pins_default>;
        pinctrl-1 = <&mmc0_pins_uhs>;
        bus-width = <8>;
        max-frequency = <200000000>;
        cap-mmc-highspeed;
        mmc-hs200-1_8v;
        mmc-hs400-1_8v;
        hs400-ds-delay = <0x14014>;
        vmmc-supply = <&reg_3p3v>;
        vqmmc-supply = <&reg_1p8v>;
        non-removable;
        no-sd;
        no-sdio;
        status = "okay";
};

上面字段改成如下就可以了

&mmc0 {
        pinctrl-names = "default", "state_uhs";
        pinctrl-0 = <&mmc0_pins_default>;
        pinctrl-1 = <&mmc0_pins_uhs>;
        bus-width = <4>;
        max-frequency = <52000000>;
        cap-sd-highspeed;
	r_smpl = <1>;
        vmmc-supply = <&reg_3p3v>;
        vqmmc-supply = <&reg_3p3v>;
        status = "okay";
};

谢谢回复，但在V21.02.3 版本中，编译过程中会有依赖错误，修改之后生成的SD镜像，启动时也会报很多jffs的错误，无法使用

使用 OpenWRT V23.05: (git.openwrt.org Git - openwrt/openwrt.git/summary) 编译生成的SD镜像，
启动没有遇到错误，但是修改
./target/linux/mediatek/files-5.15/arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3.dts
中的 &mmc0字段无效，

请问在 OpenWRT V23.05下要如何修改dts？

SD卡启动会报jffs2错误，这个建议先将sd卡进行低格再烧录。

5

用SD Formatter格式化之后，启动有改善，大概需要3分钟

不过生成的固件里面没有这种文件 mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin，
要怎么配置才能生成NAND的bin文件？

你把SD.img、snand-bl31-uboot.fip和snand-preloader.bin都烧录到nand。

8

上面的内容复制错了，是这样的

只需要写入openwrt-mediatek-mt7986-BPI-R3-NAND-WAN1-SFP1-initramfs-kernel.bin 这个吗，直接写入会无法启动

9

不是这些文件， Image文件在build_dir/target-aarch64_cortex-a53_musl/linux-mediatek_mt7986/下的*.img文件

10

如果你们希望做nand的Image，还需要一个工具来做nand Image

11

确实需要做NAND image，因为要用SD卡，
需要用什么工具，怎么做image？

12

使用sysupgrade 方式升级当前系统：(mtk-bpi-r3-NAND-WAN1-SFP1-20220928-single-image.bin)。

  • 使用NAND文件升级失败

但是启动之后，SD卡仍然不能使用

13

目前sysupgrade 不支持， 需要客户自已做二次开发

14

那相对简单的还是做Nand single Image了，这个需要怎制作？

15

single_img_wrapper-spim-nand.tgz (434.9 KB)
single_img_wrapper-spim-nor.tgz (294.6 KB)

用附件的工具。

./mk_image.sh -p mt7986a -d spim-nand -b bl2.img -f fip.bin -k openwrt-mediatek-mt7986-BPI-R3-NAND-WAN1-SFP1-squashfs-factory.bin

./mk_image.sh -p mt7986a -d spim-nor -b bl2.img -f fip.bin -k openwrt-mediatek-mt7986-BPI-R3-NOR-WAN1-SFP1-initramfs-kernel.bin

16

SD卡可以在Nand下用了，显示为 /dev/mmcblk0

不过有新问题，这个SD卡比较特殊，挂载之后只显示一个uupd.bin，
厂家说可能需要重新上电，不过热插拔会出问题，
咱们这个emmc 用sd卡之后支持热插拔吗？

17

emmc不能用sd卡
