UT-S3C6410 RAM11 Linux下LED灯驱动
UT-S3C6410 ARM11 Linux 下的LED驱动在李人东老师的要求下，让我把基于Linux下ARM的初级驱动开发流程在这里演示一遍，为了不枉费李人东老师的一片心血，和对ARM还没有入门苦苦探索的亲们，给你们开启一扇窗户，少走一些弯路，废话少说，现在开始：一、实验环境操作系统：ubuntu 9.0 或以上交叉编译环境：arm-Linux-gcc 4.2.2或以上，安装在/usr/local/arm/4.2.2/6410板子内核源码路径在：/s3c6410/linux-2.6.28-v1.0/硬件平台：UT-S3C6410开发板（其他类型的开发板也可以注意配置GPIO）注：交叉编译环境一定要装好，一般的开发板给的配套资料中都会有，安装过程也都有详细的过程，如果没有，亲，你只有自己解决了。
也可以联系我（476695721@），泪奔支持你们。
二、实验原理控制LED是最简单的一件事情，就像学C语言时候写的“hello world”程序一样，是一个入门的程序。
首先来了解一下相关的硬件知识：UT-S3C6410LED原理图UT-S3C6410LED外部引脚图从上面的原理图可以得知，LED与CPU引脚的连接方法如下，高电平点亮。
LED1 -GPM0LED2 -GPM1LED3 -GPM2LED4 -GPM3从数据手册可以找到相应的控制方法。
这里我们以LED1为例，介绍一下LED1的操作方法，其他的类似，请大家自行分析。
通过上面可以得知，需要先将GPM0设置为输出方式。
将寄存器GPMCON低四位配置成0001。
然后将GPMDAT寄存器的第0位置1灯亮，置LED0灯亮，开发板上有四个LED所以要对GPMDAT的低四位进行操作，就可以实现对灯的亮灭操作了。
三、实验步骤1、编写驱动程序driver_led.c#include <linux/module.h>#include <linux/kernel.h>#include <linux/fs.h>#include <asm/uaccess.h> /* copy_to_user,copy_from_user */#include <linux/miscdevice.h>#include <linux/pci.h>#include <mach/map.h>#include <plat/regs-gpio.h>#include <plat/gpio-bank-m.h>#include <plat/gpio-cfg.h>#define LED_MAJOR 240int led_open (struct inode *inode,struct file *filp){unsigned tmp;tmp = readl(S3C64XX_GPMCON);tmp = (tmp & ~(0xffffU))|(0x1111U);writel(tmp, S3C64XX_GPMCON);printk("#########open GPMCON######\n");return 0;}ssize_t led_read (struct file *filp, char __user *buf, size_t count,loff_t *f_pos){printk("#########read######\n");return count;}ssize_t led_write (struct file *filp, const char __user *buf, size_t count,loff_t *f_pos) {char wbuf[10];unsigned tmp;copy_from_user(wbuf,buf,count);switch(wbuf[0]){case 0: //ontmp = readl(S3C64XX_GPMDAT);tmp |= (0xfU);writel(tmp, S3C64XX_GPMDAT);break;case 1: //offtmp = readl(S3C64XX_GPMDAT);tmp &= ~(0xfU);writel(tmp, S3C64XX_GPMDAT);break;default :break;}return count;}int led_release (struct inode *inode, struct file *filp){return 0;}struct file_operations led_fops ={.owner = THIS_MODULE,.open = led_open,.read = led_read,.write = led_write,.release = led_release,};int __init led_init (void){ int rc;printk ("Test led dev\n");rc = register_chrdev(LED_MAJOR,"led",&led_fops);if (rc <0){printk ("register %s char dev error\n","led");return -1;}printk ("ok!\n");return 0;}void __exit led_exit (void){unregister_chrdev(LED_MAJOR,"led");printk ("module exit\n");return ;}module_init(led_init);module_exit(led_exit);Makefile文件Makefileobj-m:=driver_led.oKDIR:=/s3c6410/urbetter-linux2.6.28-v1.0all:make -C $(KDIR) M=$(shell pwd) modules cp driver_led.ko /home/fusq/nfs_share clean:make -C $(KDIR) M=$(shell pwd) clean2、编写测试程序test.c#include <stdio.h>#include <sys/types.h>#include <sys/stat.h>#include <fcntl.h>int main (void){int fd;char buf[10]={0,1};fd = open("/dev/my_led",O_RDWR);if (fd < 0){printf ("Open /dev/my_led file error\n");return -1;}while(1){write(fd,&buf[0],1);sleep(1);write(fd,&buf[1],1);sleep(1);}close (fd);return 0;}3、编译驱动程序与测试程序3.1编译驱动程序#make编译成驱动文件driver_led.ko并自动拷贝到了/home/fusq/nfs_share注：要注意Makefile要符合Linux下的文本格式，如果出现不执行，请在Linux下vi或vim 重新编辑一下。

The projector uses a challenge response type authentication with an MD5 (Message Digest 5) algorithm.When the projector is connected to a LAN, a random 8 bytes will be returned if authentication is enabled. Bind this received 8 bytes and the authentication password, and digest the data with the MD5 algorithm, and add it in front of the commands to send.Following is a sample of authentication process. Authentication password: password (example) Random 8 bytes: a572f60c (example)1) S elect a projector and receive the random 8 bytes from the projector. → a572f60c2)B ind the random 8 bytes and the authentication password. → a572f60cpassword3)D igest this bound with MD5 algorithm. → e3d97429adffa11bce1f7275813d4bde4)A dd this code in front of the commands and send the data. → e3d97429adffa11bce1f7275813d4bde + [command].5)W hen the sent data is correct, the command will be performed and the reply data will be returned. Otherwise, an authentication error will be returned.This projector is equipped with NETWORK BRIDGE function.When the projector connects to the computer by wired or wireless LAN communication, an external device that is connected with this projector by RS-232C communication can be controlled from the computer as a network terminal.

Linux Device DriverThis user guide explains Linux Device Driver concepts, especially the RTC drivers.1.1 What is a Device Driver?Device drivers are part of the Linux kernel. They make user space commands independent from system hardware designs so that there is no need for knowledge on hardware. There are generally two groups of users: board manufacturers and end customers.1.2 Ways to Implement a Driver as Kernel ModuleThe Maxim RTC driver is implemented in two different ways:1. Driver is released to that is the main distribution point of source code for theLinux kernel.The driver is included in the kernel that comes with the future Linux distribution. Tocompile the driver, KConfig (which is a Linux compilation feature extraction interface)must be configured to include the driver. See the Kernel Compilation Proceduresection for more information.2. Download driver from the Maxim website.Add the driver into the downloaded kernel. Then, compile with the whole kernel. Formore details, see the Kernel Compilation Procedure section.Figure 1. Kernel image w/out modules.Linux has a proper way to inject a driver into the running Linux distribution or Linuxkernel module (LKM). The LKMs are not part of the main kernel. They are injected byusers into the running kernel. The user can determine which LKM driver to include forkernel compilation. This helps to reduce the size of the kernel. For example, theethernet LKM can be eliminated in a kernel compilation if an ethernet interface is notneeded in a system. So, the bootloader and kernel module loader do not try to loadthe LKM into the RAM.The LKM files are usually kept in the /lib/modules folder. They are loaded according to thedistribution configuration such as device tree, scripts, etc.1.3 Device Driver StructureFigure 2. Linux device management [1].Kernel developers generate Linux’s generic device driver. The device driver must support all the required features and functions. The driver code should report it in the device driver structures if optional features are not implemented.2. Device Tree ParametersDevice drivers must learn hardware parameters due to the nature of the hardware environment. For example, the CPU’s model, active core number, clock frequency, board’s memory inputs, memory over bus drivers, which device is connected to which bus, almost everything is described in the device tree of the system. This feature supports Arm after Linux Kernel Version 3.7. The device tree is the hardware description for the kernel usually provided by the board manufacturer/provider.2.1 RTC Device TreesThe RTC device trees usually contain information on the bus and signals connected to the RTC. Rest of the settings are device-specific parameters dependent on the RTC IC model and on-board design.The bus number, interrupt lines, and device addresses are interpreted within the kernel. So, the driver only gets necessary bus structures from high-level application program interfaces (APIs). However, the device driver must have parser and default values for custom parameters like trickle charger settings or power management mode.Figure 3. Device tree workflow [2].2.2 Device Tree CompilationThe device tree has its own compiler to generate output. More information can be found here:device-tree-compiler/manual.txt at master · vagrantc/device-tree-compiler · GitHub.3. Linux Generic RTC Device DriversThe RTC device driver is a generic device driver for RTC ICs from manufacturers. System calls must be used in user space programs to access driver features from the user space. The IOCTL call is used to access the RTC features for the RTC driver.Figure 4. System calls to device drivers [1].3.1 RTC-Specific Default FeaturesM: Must have, O: Optional, N: Nice to have.An invalid argument system code is returned to the user space if the must-have and optional features are not implemented. The user space programs can read the return code and respond to it if needed when the optional features are not implemented. Everything must be implemented for the must-have options.Nice-to-have features may not be implemented in the kernel space.An RTC driver is ready to release on and work in a Linux system with the features mentioned in Table 1.3.2 Device-Specific Custom FeaturesThe RTC ICs may have more features than Linux requires. These features can be utilized through the IOCTL system calls and/or SysFs file interface.Using the file APIs can change the device attribute or configuration using sysfs. A single sysfs file usually maps to a single attribute and is usually readable (and/or writable) using a simple text string. For example, the use of cat to read the state of the power management configuration and the echo shell command to change it.Sysfs is a pseudo file system that can be used by the end/mid user. Those files are usually read-only files. But, some can take parameters through the command line. For example, •$ echo out >/sys/class/gpio/gpio24/direction•$ cat /sys/class/gpio/gpio24/directionout•$ echo 1 >/sys/class/gpio/gpio24/valueThe cat program reads data from a file in the Linux environment. Likewise, the echo program writes data to a file.Every IOCTL option has its own function-specific code. The user and kernel spaces must have the same code numbers. So, the user space programs can use IOCTL functions through system calls.Again, the user can use the command line or Linux’s file API to access the sysfs as files.The end/mid user must know the parameters to give and read in both the options. Figure 5 shows an example.Figure 5. IOCTL parameters for MAX31343.4. MAX31343 Device Driver Package 4.1 Supported FeaturesHere is the driver for Linux Kernel 4.x.x.The driver must be compiled from the source code for portability. The Raspberry Pi kernel must be updated to the latest version before the compilation as shown in Figure 6.• sudo apt-get update && sudo apt-get install --reinstall raspberrypi-bootloaderraspberrypi-kernelThe RPi must then reboot with the reboot command.Figure 6. Commands to prepare the Raspberry Pi for device driver compilation.Kernel headers must be installed to compile the MAX31343 LKM. • sudo apt-get install raspberrypi-kernel-headersThe command installs the necessary kernel headers for development.RPi 3 B+ does not use i 2c automatically. So, enable the i 2c bus and RTC in /boot/config.txt.• sudo nano /boot/config.txtUse the command to open the file and add the following lines:o dtparam=i2c_arm=on odtoverlay=i2c-rtc,MAX31343A Makefile is required to create the LKM from the driver file. A Makefile is provided to work with Raspberry Pi 3B+. The Makefile can be used to compile the driver, device tree, and install the LKM to run the Linux system. • Go to the folder with the Makefile.• The make clean command clears all outputs of the driver.• The make all command compiles the driver and generates the LKM (.ko) file as shownin Figure 7.Figure 7. Command for compiling the device driver.• The sudo make install command installs the driver into the LKM folder as shown inFigure 8. Most system folders are not accessible to users. Use thesudocommand to allow make command to make changes to system directories. This step is required for installing the driver to the system.Figure 8. Command for installing the device driver to the system.• The make dtbs command compiles the device tree overlay (i 2c-rtc-overlay.dts) asshown in Figure 9 and generates the i 2c-rtc.dtbo output. It copies the output to RPi’s /boot/overlays folder if the compilation is successful.Figure 9. Command for compiling and installing the device tree overlay. Restart the Raspberry Pi after these steps. The driver is ready for testing.4.1.1 Basic TestsThe timedatectl and hwclock commands can be used for basic tests such as setting/reading time. These commands are provided by the Raspberry Pi OS. So, they do not require any installation.Manually disable the Network Time Protocol (NTP) before any test. The NTP updates the system time periodically if not disabled.• sudo timedatectl set-ntp noThe command disables the NTP as shown in Figure 10.Figure 10. Commands for disabling NTP.The hwclock command can be used to set the time in the RTC.• Set RTC time: “sudo hwclock -- set --date “1/27/2020 14:50:00”Figure 11. Command for changing the RTC time.• Read RTC time: “timedatectl” or “sudo hwclock -r”Figure 12. Reading RTC time using systemctl.Figure 13. Reading RTC time using hwclock.• Synchronizing system clock with RTC: “sudo hwclock --hctosys”Figure 14. Sycnhronizing system clock with RTC. 4.1.2 SysFs Entry Test of the Maxim Version DriverThere is only one writable sysfs entry (userram) on this version of the driver. This interface is a nice-to-have feature from the Linux kernel, which is defined as the sysfs. Other sysfs entries are there to read some of the importantconfigurations.Sysfsentries can be found in the “/sys/class/rtc/rtc<device_no>/device” folder.The cat power_mgmt command reads the current power-management mode and backup battery threshold from the RTC as shown in Figure 15. Change these settings using the IOCTL or device tree.Figure 15. Reading power management mode.The cat trickle_charger command reads the trickle charger settings as shown in Figure 16. Change the settings in the device tree.Figure 16. Reading the trickle charger settings.A sysfs entry allows only a root user to write data. • sudo -sEnter the command mentioned above to change the user mode.Figure 17. Command for changing the user mode.The userram (nvmem) is a binary interface unlike other sysfs entries. So, the cat command does not show meaningful data.• hexdump -C userramUse this command to read as shown in Figure 18.Figure 18. Reading RTC userram with hexdump.The root user access is a must to write data to userram. • echo “<data>” >> userramThe command works after getting access. • echo -n -e “<data in binary format>” >> userramThe command works to write data in binary.Figure 19. Writing data to RTC userram.Use the cat additional_interrupt command to see the status of the remaining interrupts not used by the kernel. These are analog power fail, D1 input, loss of external clock, and oscillator failed interrupts. If no interrupt is asserted:Figure 20. Reading the additional interrupt status.If interrupts are asserted:Figure 21. Command output when the interrupts are asserted.A test program, rtc_ctest, is provided to test the IOCTL options including the userram,update interrupt, alarm interrupt, and sysfs read values. Call the program with securityprivilege.•sudo chmod 777 rtc_ctestRun the command mentioned above to ensure the file is readable, writable, andexecutable.•sudo ./rtc_ctestThe command calls the program.Figure 22. Command output of RTC test script.Install the necessary packages first to use the test program in Python. Install them withthe following commands:•sudo pip3 install ioctl-opt•sudo pip3 install pytzFigure 24. Installing dependencies.After installing the necessary packages, run the program with the following command:•sudo python3 rtc_python3Test.py “/dev/rtc0”Figure 25. Command output of RTC Python test script.4.2 Kernel Compilation ProcedureAnother way to compile and run the driver is to compile it with the whole kernel. Follow these instructions to build the kernel in the computer: (Ubuntu is used here to build the kernel. Use this link for another system.)First, download and install toolchain with the following commands:• git clone https:///raspberrypi/tools ~/tools• echo PATH=\$PATH:~/tools/arm-bcm2708/arm-linux-gnueabihf/bin >> ~/.bashrc• source ~/.bashrcInstall an additional set of libraries for a 32-bit operating system (for example, Raspberry Pi Desktop for the PC):• sudo apt install zlib1g-dev:amd64Download the kernel source after these steps:• git clone --depth=1 https:///raspberrypi/linuxEnsure the needed dependencies are there on the machine to build the sources for cross-compilation. Execute the following command:• sudo apt install git bc bison flex libssl-dev make libc6-dev libncurses5-devFigure 26. Downloading the required tools for compiling the Raspberry Pi kernel.Figure 27. Downloading the Linux kernel for Raspberry Pi.Copy rtc-MAX31343.c in ./linux/drivers/rtc after these steps.Figure 28. Installing the system dependencies for kernel compiling.Figure 29.
