如何确认nand.img分区里是否有splash.bmp  ?挂载后啥也看不到,不像SD卡镜像都能查看各个分区内容

genimage-nand.cfg文件:

flash nand-128M {
    pebsize = 128K
    numpebs = 1024
    minimum-io-unit-size = 2048
}

image sysimage-nand.img {
    flash {}
    flashtype = "nand-128M"

    partition u-boot {
        image = "u-boot-sunxi-with-nand-spl.bin"
        size = 512K
    }

    partition splash {
        offset = 0x80000
        image = "splash.bmp"
        size = 512K
    }

    partition kernel {
        offset = 0x100000
        image = "kernel.itb"
        size = 5M
    }

    partition rom {
        offset = 0x600000
        image = "rootfs.squashfs"
    }
}

这个问题是图片格式问题，修改为RGB888就行了，原来的是ARGB888，RGB565格式也会提示Error: compression type 3 not supported
