Enable eMMC on NanoPi R2C Plus

[lucascgo]

Hello everyone,

 

I'm running the image from NanoPi R2S on a NanoPi R2C Plus (that has 8 GB eMMC). Is well working, but I would like to install the OS on the eMMC. Is it possible?

 

Thanks.

It's easy to enable

 

For example, in the r2s options, the “current” option means installing the 6.12 kernel. And according to the content of `config/boards/nanopi-r2s.csc` file, the dts file is `rk3328-nanopi-r2-rev00.dts`. 

 

Then go to `patch/kernel/archive/rockchip64-6.12/dt/` and modify the file `rk3328-nanopi-r2-rev00.dts`.

 

// If you want to enable eMMC, find the following

&emmc {
	status = "disabled";
};

// Modified to

&emmc {
	status = "okey";
};

 

 

By the way If you want to enable sdio wifi, follow these

 

// find the following

&sdmmc_ext {
	status = "disabled";
};

&sdio_pwrseq {
	status = "disabled";
};

// Modified to

&sdmmc_ext {
        vmmc-supply = <&vcc_io>;
        vqmmc-supply = <&vcc_18>;
        max-frequency = <150000000>;
        sd-uhs-sdr104;
        status = "okay";

        /delete-node/ bcrmf@1;
        rtl8822cs@1 {
                reg = <1>;
                compatible = "realtek,rtl8822cs";
        };
};

&sdmmc0ext_clk {
        rockchip,pins = <3 RK_PA2 3 &pcfg_pull_none_8ma>;
};

&sdmmc0ext_cmd {
        rockchip,pins = <3 RK_PA0 3 &pcfg_pull_up_8ma>;
};

&sdmmc0ext_bus4 {
        rockchip,pins =
                <3 RK_PA4 3 &pcfg_pull_up_8ma>,
                <3 RK_PA5 3 &pcfg_pull_up_8ma>,
                <3 RK_PA6 3 &pcfg_pull_up_8ma>,
                <3 RK_PA7 3 &pcfg_pull_up_8ma>;
};

&sdio_pwrseq {
        status = "okay";
};

 

Finally, just recompile.
