## 使用GPIO操作I2C设备_IMX6ULL

|
||||
|
||||
### 1. 硬件连接
|
||||
|
||||
* IMX6ULL：把I2C模块接到GPIO
|
||||
|
||||
|
||||
|
||||
|
||||
### 2. 根据原理图编写设备树
|
||||
|
||||
#### 2.1 原理图
|
||||
|
||||
|
||||
|
||||
#### 2.2 编写设备树
|
||||
|
||||
```shell
|
||||
i2c_gpio_100ask {
|
||||
compatible = "i2c-gpio";
|
||||
gpios = <&gpio4 20 0 /* sda */
|
||||
&gpio4 21 0 /* scl */
|
||||
>;
|
||||
i2c-gpio,delay-us = <5>; /* ~100 kHz */
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
};
|
||||
```
|
||||
|
||||
把上述代码，放入`arch/arm/boot/dts/100ask_imx6ull-14x14.dts`的根节点下面。
|
||||
|
||||
### 3. 确认内核已经配置了I2C-GPIO
|
||||
|
||||
查看内核目录下的`.config`，如果未设置`CONFIG_I2C_GPIO`，上机实验时需要配置内核、编译I2C-GPIO驱动。
|
||||
|
||||
|
||||
|
||||
### 4. 上机实验
|
||||
|
||||
#### 4.1 设置工具链
|
||||
|
||||
* IMX6ULL
|
||||
|
||||
```shell
|
||||
export ARCH=arm
|
||||
export CROSS_COMPILE=arm-linux-gnueabihf-
|
||||
export PATH=$PATH:/home/book/100ask_imx6ull-sdk/ToolChain/gcc-linaro-6.2.1-2016.11-x86_64_arm-linux-gnueabihf/bin
|
||||
```
|
||||
|
||||
|
||||
#### 4.2 编译、替换设备树
|
||||
|
||||
* 编译设备树：
|
||||
在Ubuntu的IMX6ULL内核目录下执行如下命令,
|
||||
得到设备树文件：`arch/arm/boot/dts/100ask_imx6ull-14x14.dtb`
|
||||
|
||||
```shell
|
||||
make dtbs
|
||||
```
|
||||
|
||||
* 复制到NFS目录：
|
||||
|
||||
```shell
|
||||
$ cp arch/arm/boot/dts/100ask_imx6ull-14x14.dtb ~/nfs_rootfs/
|
||||
```
|
||||
|
||||
* 开发板上挂载NFS文件系统
|
||||
|
||||
* vmware使用NAT(假设windowsIP为192.168.1.100)
|
||||
|
||||
```shell
|
||||
[root@100ask:~]# mount -t nfs -o nolock,vers=3,port=2049,mountport=9999
|
||||
192.168.1.100:/home/book/nfs_rootfs /mnt
|
||||
```
|
||||
|
||||
* vmware使用桥接，或者不使用vmware而是直接使用服务器：假设Ubuntu IP为192.168.1.137
|
||||
|
||||
```shell
|
||||
[root@100ask:~]# mount -t nfs -o nolock,vers=3 192.168.1.137:/home/book/nfs_rootfs /mnt
|
||||
```
|
||||
|
||||
* 更新设备树
|
||||
|
||||
```shell
|
||||
[root@100ask:~]# cp /mnt/100ask_imx6ull-14x14.dtb /boot
|
||||
[root@100ask:~]# sync
|
||||
```
|
||||
|
||||
* 重启开发板
|
||||
|
||||
#### 4.3 编译I2C-GPIO驱动
|
||||
|
||||
##### 1. 配置内核
|
||||
|
||||
在IMX6ULL内核源码目录下执行`make menuconfig`命令，如下配置内核：
|
||||
|
||||
```shell
|
||||
Device Drivers --->
|
||||
I2C support --->
|
||||
I2C Hardware Bus support --->
|
||||
<M> GPIO-based bitbanging I2C // 输入M，编译为模块
|
||||
```
|
||||
|
||||
|
||||
|
||||
##### 2. 编译模块
|
||||
|
||||
设置工具链后，在内核目录下执行：
|
||||
|
||||
```shell
|
||||
make modules // 得到 drivers/i2c/busses/i2c-gpio.ko
|
||||
```
|
||||
|
||||
|
||||
|
||||
#### 5. 测试
|
||||
|
||||
在开发板上执行：
|
||||
|
||||
```shell
|
||||
[root@100ask:~]# i2cdetect -l // 加载i2c-gpio.ko前只看到2条I2C BUS
|
||||
i2c-1 i2c 21a4000.i2c I2C adapter
|
||||
i2c-0 i2c 21a0000.i2c I2C adapter
|
||||
[root@100ask:~]#
|
||||
[root@100ask:~]# insmod /mnt/i2c-gpio.ko
|
||||

|
||||
[root@100ask:~]# i2cdetect -l // 加载i2c-gpio.ko后看到3条I2C BUS
|
||||
i2c-1 i2c 21a4000.i2c I2C adapter
|
||||
i2c-4 i2c i2c_gpio_100ask I2C adapter
|
||||
i2c-0 i2c 21a0000.i2c I2C adapter
|
||||
[root@100ask:~]#
|
||||
[root@100ask:~]# i2cdetect -y 4 // 检测到0x50的设备

||||

|
||||
|
||||
### 1. 硬件连接
|
||||
|
||||
* STM32MP157：把I2C模块接到GPIO
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### 2. 根据原理图编写设备树
|
||||
|
||||
#### 2.1 原理图
|
||||
|
||||
|
||||
|
||||
#### 2.2 编写设备树
|
||||
|
||||
```SHELL
|
||||
i2c_gpio_100ask {
|
||||
compatible = "i2c-gpio";
|
||||
gpios = <&gpioa 13 0 /* sda */
|
||||
&gpiod 8 0 /* scl */
|
||||
>;
|
||||
i2c-gpio,delay-us = <5>; /* ~100 kHz */
|
||||
#address-cells = <1>;
|
||||
#size-cells = <0>;
|
||||
};
|
||||
```
|
||||
|
||||
修改`arch/arm/boot/dts/stm32mp157c-100ask-512d-lcd-v1.dts`，在根节点下添加上述代码。
|
||||
|
||||
### 3. 确认内核已经配置了I2C-GPIO
|
||||
|
||||
查看内核目录下的`.config`，如果未设置`CONFIG_I2C_GPIO`，上机实验时需要配置内核、编译I2C-GPIO驱动。
|
||||
|
||||
### 4. 上机实验
|
||||
|
||||
#### 4.1 设置工具链
|
||||
|
||||
* STM32MP157
|
||||
|
||||
```shell
|
||||
export ARCH=arm
|
||||
export CROSS_COMPILE=arm-buildroot-linux-gnueabihf-
|
||||
export PATH=$PATH:/home/book/100ask_stm32mp157_pro-sdk/ToolChain/arm-buildroot-linux-gnueabihf_sdk-buildroot/bin
|
||||
```
|
||||
|
||||
|
||||
#### 4.2 编译、替换设备树
|
||||
|
||||
* 编译设备树：
|
||||
在Ubuntu的STM32MP157内核目录下执行如下命令,
|
||||
得到设备树文件：`arch/arm/boot/dts/stm32mp157c-100ask-512d-lcd-v1.dtb`
|
||||
|
||||
```shell
|
||||
make dtbs
|
||||
```
|
||||
|
||||
* 复制到NFS目录：
|
||||
|
||||
```shell
|
||||
$ cp arch/arm/boot/dts/stm32mp157c-100ask-512d-lcd-v1.dtb ~/nfs_rootfs/
|
||||
```
|
||||
|
||||
* 开发板上挂载NFS文件系统
|
||||
|
||||
* vmware使用NAT(假设windowsIP为192.168.1.100)
|
||||
|
||||
```shell
|
||||
[root@100ask:~]# mount -t nfs -o nolock,vers=3,port=2049,mountport=9999
|
||||
192.168.1.100:/home/book/nfs_rootfs /mnt
|
||||
```
|
||||
|
||||
* vmware使用桥接，或者不使用vmware而是直接使用服务器：假设Ubuntu IP为192.168.1.137
|
||||
|
||||
```shell
|
||||
[root@100ask:~]# mount -t nfs -o nolock,vers=3 192.168.1.137:/home/book/nfs_rootfs /mnt
|
||||
```
|
||||
|
||||
* 确定设备树分区挂载在哪里
|
||||
|
||||
由于版本变化，STM32MP157单板上烧录的系统可能有细微差别。
|
||||
在开发板上执行`cat /proc/mounts`后，可以得到两种结果(见下图)：
|
||||
|
||||
* mmcblk2p2分区挂载在/boot目录下(下图左边)：无需特殊操作，下面把文件复制到/boot目录即可
|
||||
|
||||
* mmcblk2p2挂载在/mnt目录下(下图右边)
|
||||
|
||||
* 在视频里、后面文档里，都是更新/boot目录下的文件，所以要先执行以下命令重新挂载：
|
||||
* `mount /dev/mmcblk2p2 /boot`
|
||||
|
||||
|
||||
|
||||
* 更新设备树
|
||||
|
||||
```shell
|
||||
[root@100ask:~]# cp /mnt/stm32mp157c-100ask-512d-lcd-v1.dtb /boot/
|
||||
[root@100ask:~]# sync
|
||||
```
|
||||
|
||||
* 重启开发板
|
||||
|
||||
#### 4.3 编译I2C-GPIO驱动
|
||||
|
||||
##### 1. 配置内核
|
||||
|
||||
在STM32MP157内核源码目录下执行`make menuconfig`命令，如下配置内核：
|
||||
|
||||
```shell
|
||||
Device Drivers --->
|
||||
I2C support --->
|
||||
I2C Hardware Bus support --->
|
||||
<M> GPIO-based bitbanging I2C // 输入M，编译为模块
|
||||
```
|
||||
|
||||
|
||||
|
||||
##### 2. 编译模块
|
||||
|
||||
设置工具链后，在内核目录下执行：
|
||||
|
||||
```shell
|
||||
make modules // 得到 drivers/i2c/busses/i2c-gpio.ko
|
||||
```
|
||||
|
||||
|
||||
|
||||
#### 5. 测试
|
||||
|
||||
在开发板上执行：
|
||||
|
||||
```shell
|
||||
[root@100ask:~]# i2cdetect -l // 加载i2c-gpio.ko前只看到3条I2C BUS

Pins_Tool_for_i.MX_Processors_v6_x64.exe 文件太大了,
|
||||
无法上传到GIT。
|
||||
|
||||
可以去百度网盘下载,
|
||||
方法如下:
|
||||
1. 打开 download.100ask.net
|
||||
2. 找到"100ASK_IMX6ULL_PRO开发板", 它里面开发板配套资料的百度网盘的下载链接
|
||||
3. 下载网盘资料后，点击进入目录: "01_Tools (工具)/IMX_pinsTools"
|
||||
4. 里面有2个文件:
|
||||
Pins_Tool_for_i.MX_Processors_v6_x64.exe
|
||||
MCIMX6Y2xxx08.mex
|
||||
5. 把它们转存到你自己的网盘, 再用百度网盘软件下载。
|
||||
建议不要用浏览器直接下载, 容易出错。
