Peripheral NANDEdit

Device tree configurationEdit

 

If user use petalinux-config for configuration NAND partition this is not apply to device-tree correctly.

Here below an example of device tree configuration used on standard DAVE's kit for the BORA Lite NAND flash:

From bora.dtsi: 

...
...
&nand0{
    partition@nand-bootbin {
        label = "bootbin";
        reg = <0x00000000 0x01600000>;
    };

    partition@nand-ubootenv {
        label = "ubootenv";
        reg = <0x01600000 0x00040000>;
    };

    partition@nand-rootfs {
        label = "rootfs";
        reg = <0x01640000 0x0>;
    };
};
...
...
