• 更改boot

  scp jay@10.28.3.204:/home/jay/a64_jay/linux-3.10/output/boot.img ./
  dd if=boot.img of=/dev/mmcblk0p6 bs=1M

驱动

摄像头(ov5640.ko vfl2.ko )

需要修改vfe.c

//linux-3.10/drivers/media/platform/sunxi-vfe/vfe.c
static int vidioc_g_input(struct file *file, void *priv, unsigned int *i)  {
        struct vfe_dev *dev = video_drvdata(file);

        //*i = dev->input;
        *i = 0;
        return 0;
}

//linux-3.10/drivers/media/platform/sunxi-vfe/vfe.c
static int vidioc_enum_input(struct file *file, void *priv, struct v4l2_input *inp) {
         struct vfe_dev *dev = video_drvdata(file);
         if (inp->index > dev->dev_qty-1) {
                 vfe_err("input index(%d) > dev->dev_qty(%d)-1 invalid!\n", inp->index, dev->dev_qty);
                 return -EINVAL;
         }
         vidioc_s_input(file,priv,inp->index);
         if (0 == dev->device_valid_flag[inp->index]) {
                 vfe_err("input index(%d) > dev->dev_qty(%d)-1 invalid!, device_valid_flag[%d] = %d\n",
                         inp->index, dev->dev_qty,inp->index, dev->device_valid_flag[inp->index]);
                 return -EINVAL;
         }
         inp->type = V4L2_INPUT_TYPE_CAMERA;
         return 0;
 }

同时直接干掉无线网卡支持。

通过SID 生成mac地址。

//linux-3.10/drivers/net/usb/asix_devices.c
extern int sunxi_get_soc_chipid(u8 *chipid);
sunxi_get_soc_chipid(chipid);
        buf[0] = 0x02; /* Non OUI / registered MAC address */
        buf[1] = chipid[0];
        buf[2] = chipid[12];
        buf[3] = chipid[13];
        buf[4] = chipid[14];
        buf[5] = chipid[15];
        netdev_dbg(dev->net,"MDP MAC from SID: 02:%02x:%02x:%02x:%02x:%02x",
                buf[1], buf[2], buf[3],
                buf[4], buf[5]);

        asix_set_netdev_dev_addr(dev, buf);

//inux-3.10/drivers/char/sunxi_sys_info/chipid-sunxi.c        
pr_info("%s,%d: sun50i_sid_base  :%08x \n", __func__, __LINE__,(unsigned int)sun50i_sid_base );
        //sunxi_soc_chipid[1] = readl(sun50i_sid_base + 0x200 + 0x4);
        //sunxi_soc_chipid[2] = readl(sun50i_sid_base + 0x200 + 0x8);
        //sunxi_soc_chipid[3] = readl(sun50i_sid_base + 0x200 + 0xc);
        pr_info("%s,%d: sunxi_soc_chipid  :0x%04x-%04x-%04x-%04x \n", __func__, __LINE__,sunxi_soc_chipid[0],sunxi_soc_chipid[1],sunxi_soc_chipid[2],sunxi_soc_chipid[3]);
        sunxi_soc_chipid[0] = readl(sun50i_sid_base );
        sunxi_soc_chipid[1] = readl(sun50i_sid_base + 0x4);
        sunxi_soc_chipid[2] = readl(sun50i_sid_base + 0x8);
        sunxi_soc_chipid[3] = readl(sun50i_sid_base + 0xc);
        pr_info("%s,%d: sunxi_soc_chipid  :0x%04x-%04x-%04x-%04x \n", __func__, __LINE__,sunxi_soc_chipid[0],sunxi_soc_chipid[1],sunxi_soc_chipid[2],sunxi_soc_chipid[3]);

并且需要使能system info driver。
