AM625: OSPI Nand flash读错误

Part Number:AM625

1,使用GIgoDevice 5G2GM OSPI nand flash 读错误,写入操作好像没有问题

2,设备树为:

&ospi0 {

    status = "okay";

    pinctrl-names = "default";

    pinctrl-0 = <&ospi0_pins_default>;

 

    flash@0{

        compatible = "spi-nand";

        reg = <0x0>;

        spi-tx-bus-width = <4>;

        spi-rx-bus-width = <4>;

        spi-max-frequency = <25000000>;

 

        //spi-max-frequency = <500000000>;

        cdns,tshsl-ns = <60>;

        cdns,tsd2d-ns = <60>;

        cdns,tchsh-ns = <60>;

        cdns,tslch-ns = <60>;

        cdns,read-delay = <2>;

 

        bits-per-word = <8>;

    };

};

3,mtd_speedtest测试会提示读失败,写入操作好像没有问题。

4,

我们把/dev/mtd0挂载到ubifs系统中,如果重启后,再读取里面的文件有一定概率出现下面的读取错误,

按照规律是写入没有出现过问题,读取操作的确很容易出错误
