 Find the tl_led_flash folder. The tl_led_flash folder x contains the bin folder and the src folder. The bin folder is the official compiled test routine, which can be used directly for testing. The src folder contains the source files, which can be re-modified and compiled to generate new executable files.

 Open the tl_led_flash.c file, and you can modify the code in the file to implement new functions. We provide the simplified source code. The function of this code is to realize the flashing of three green LED lights on the development board. The source code is as follows: ```c /* Copyright 2018 Tronlong Elec. Tech. Co. Ltd. All Rights Reserved. */ #include<stdio.h>

#include<stdlib.h>

#include<stdint.h>

#include<stdbool.h>

#include<string.h>

#include<getopt.h>

#include<signal.h>

#include<unistd.h>

#include<errno.h>

#include<libgen.h>

/* Get array size */ #define ARRAY_SIZE(array) sizeof(array) / sizeof(array[0]) /* User-operable LEDs */ static char *g_leds[] = { "/sys/class/leds/user -led0", "/sys/class/leds/user-led1", "/sys/class/leds/user-led2", "/sys/class/leds/user-led3" }; int main() { int i = 0; int c = 0; int num = 3; int flag = 0; char cmd[64] = {0}; printf("LED Test!!!/n"); while (1) { /* Turn on LEDs */ for (i = 0; i < num; i++) { /* Set the LED brightness value to 1 to turn on the led */ snprintf(cmd, 64, "echo 1 > %s/brightness", g_leds<i>); if (system(cmd) != 0) { fprintf(stderr, "Error: Failed to turn on %s\n", g_leds<i>); exit(EXIT_FAILURE); } } /* Keep the LEDs on for 500 ms */ usleep(500 * 1000); /* Turn off LEDs */ for (i = 0; i < num; i++) { /* Set the LED brightness value to 0 to turn off the LED * / snprintf(cmd, 64, "echo 0 > %s/brightness", g_leds<i>); if (system(cmd) != 0) { fprintf(stderr, "Error: Failed to turn off %s\n" , g_leds<i>); exit(EXIT_FAILURE); } } /* Keep the LEDs off for 500 ms */ usleep(500 * 1000); } printf("Exit\n"); return 0; } ``` Remember to save the program after writing. The source code writing is basically completed. Now start compiling the source code. ## 2. TL5708 development board program compilation Speaking of compilation, here are two compilation methods. Compilation method 1: The base-demos directory stores common Linux development cases, the bin directory of the case stores executable files, and the src directory of the case stores source code. python -demos directory stores Python development cases. Case script files do not need to be compiled and can be run directly. If you need to recompile Linux common development cases, please copy the src directory of the corresponding case to the Ubuntu working directory, enter the src directory and execute the following command to load the Linux Processor SDK environment variables, and execute the make command to compile the case. After the compilation is complete, an executable file will be generated in the current directory. Method 1: The compilation instructions are as follows: ```c source /home/libai/ti-processor-sdk-linux-rt-am57xx-evm-04.03.00.05/linux-devkit/environment-setup make ``` Compilation method 2: During development, you need to specify the Processor-SDK development kit cross compiler for the corresponding platform, and then compile the Linux common routines to generate the executable file for the corresponding platform. The Processor-SDK cross compiler path that needs to be specified for each platform can be referred to in the following table: [attach ]529272[/attach] Open Ubuntu and execute the following command in the path where the example source code is located. Use "CC=" to point to the specific cross-compiler of the current platform, and use the "make" command to compile the example source code. Method 2: The compilation instructions are as follows: ```c CC=/home/libai/ti-processor-sdk-linux-rt-am57xx-evm-04.03.00.05/linux-devkit/sysroots/x86_64-arago-linux/usr/bin /arm-linux-gnueabihf-gcc make ``` Both compilation methods can compile source files. In this tutorial, we will use compilation method 2. Next, open the Ubuntu system terminal and start compiling. First, you need to locate the source The directory where the file is located. ```c cd /home/libai/AM57xx/base-demos/tl_led_flash ls cd src ls ``` Implement the above code step by step, and the running results are as follows:

 Then enter the compilation command of method 2: ` ``c CC=/home/libai/ti-processor-sdk-linux-rt-am57xx-evm-04.03.00.05/linux-devkit/sysroots/x86_64-arago-linux/usr/bin/arm-linux-gnueabihf- gcc make ls ```

 No error message appears, which means the source code compilation has been completed. ##3. TL5708 development board program burning When burning the program, it is necessary to transfer files between the PC and the development board, so the IP address needs to be allocated to put the PC and the development board in the same network segment. For specific configuration, please refer to the above post: [When the TL5708 development board does not have a router, connect the PC and the development board with a network cable and place them in the same network segment to transfer files](https://en.eeworld.com/bbs/thread-1159503- 1-1.html "When the TL5708 development board does not have a router, connect the PC and the development board with a network cable and place them in the same network segment to transfer files to each other") We need to transfer the executable file generated in the box below to the development board:

 100% means the transmission is successful. Now open the development board system and enter the command to see if the executable file is received. ```c cd / ls ```

 After checking, it was found that the development board had successfully received the file. ##Fourth, TL5708 development board program running Enter the following command in the development board system to run the code: ```c ./tl_led_flash ``` The phenomenon is as follows:
