# GAC-350 Kernel Compile

## 命令

* 单独编译Kernel

  ```shell
  ./build.sh -p sun50iw1p1_debian -m kernel -k linux-3.10
  ```

* 清除

  ```
  ./build.sh -p sun50iw1p1_debian -m distclean -k linux-3.10
  ```

* menuconfig

  ```
  sudo make ARCH=arm64 CROSS_COMPILE=../out/sun50iw1p1/debian/common/buildroot/external-toolchain/bin/aarch64-linux-gnu- menuconfig
  ```

* 拷贝

  ```
  scp jay@10.28.3.204:/home/jay/a64/linux-3.10/drivers/net/usb/* ./
  ```

* 完整测试命令

  ```shell
  t/usb/*.ko ./    ~/asix# scp jay@10.28.3.204:/home/jay/a64/linux-3.10/drivers/ne

* 更改boot

  ```powershell
  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

```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; } ```

```c 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; } ``` > Device Drivers > Multimedia support > V4L platform devices  ### GPIO libc（built in） > Device Drivers > GPIO Support  ### SMT32 I2C& 开机动画（stm_s103.ko） >Device Drivers > Staging drivers > Support for MXJ private driver  ### USB Net(usbnet.ko asix.ko) > Device Drivers > Network device support > USB Network Adapters  同时直接干掉无线网卡支持。 ### 通过SID 生成mac地址。 ```c 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);

```

```c 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`。

Device Drivers > Character devices


### 显示(built-in)

Device Drivers > Graphics support > Support for frame buffer devices > Video support for sunxi


### STM32&I2C更新

19:27 2018/7/31

更新为源码自带i2c通用驱动，并且更新速率为`100k`

Device Drivers > I2C support
