manage emmc mount path during boot

Question

Hello,

I am using a PicoZed with PetaLinux 2016.2 , the emmc appear as /run/media/mmcblk0 or /run/media/mmcblk1 depending of the detection of the SD card during kernel boot.

How can I always find the emmc at /run/media/mmcblk0 and the SD card at /run/media/mmcblk1?

Thanks you

I found my solution,

You need to change the device tree

in system-top.dts:

You need to add a new declaration of the sd controller and to disable the old sd controller:

add:
&sdhci0 {
    status = "disabled";
};

and add in amba: amba:
sdhci2: sdhcibis@e0100000 {
   compatible = "arasan,sdhci-8.9a";
   status = "okay";
   clock-names = "clk_xin", "clk_ahb"; clocks = <&clkc 21>, <&clkc 32>;
   interrupt-parent = <&intc>; interrupts = <0 24 4>;
   reg = <0xe0100000 0x1000>;
xlnx,has-cd = <0x1>;
xlnx,has-power = <0x1>;
xlnx,has-wp = <0x1>;
};
