| # ESP32 Hello World | ||
|
|
||
| When JTAG doesn't work, often for infinite-loop failing app, | ||
| this simple "Hello World" app, programmed via serial port can help. | ||
|
|
||
| The file size for the enclosed `esptool.exe` 3,491,344 bytes and the SHA-256 value is: | ||
|
|
||
| `1B-EB-B7-CA-09-F0-4F-98-A7-93-DC-EE-F6-19-C4-78-78-7F-08-9E-DA-14-E4-74-76-B6-5A-B6-13-4D-25-9D` | ||
|
|
||
|
|
||
|
|
||
| Here's a sample SHA-256 file calculation in C# | ||
|
|
||
| ``` | ||
| using System.Security.Cryptography; | ||
| using System.Text; | ||
| using System.IO; | ||
| namespace TestdriveSHA256 | ||
| { | ||
| class Program | ||
| { | ||
| static void Main(string[] args) | ||
| { | ||
| using (SHA256 mySHA256 = SHA256.Create()) | ||
| { | ||
| byte[] stringBytes = Encoding.ASCII.GetBytes("Hello World"); | ||
| stringBytes = File.ReadAllBytes(@"C:\workspace\wolfssl-examples\ESP32\ESP32-hello-world\esptool.exe"); | ||
| byte[] hashValue = mySHA256.ComputeHash(stringBytes); | ||
| string resultValue = System.BitConverter.ToString(hashValue); | ||
| System.Console.WriteLine(resultValue); | ||
| } | ||
| } | ||
| } | ||
| } | ||
| ``` | ||

||
| ## ESP-IDF | ||
|
|
||
| Although the examples were created using VisualGDB extension for Visual Studio, the | ||
| examples can be compiled using the ESP-IDF. | ||
|
|
||
| Once the EDP-IDF is installed, use the [setp_win.bat]() to copy wolfSSL files to | ||
| the `esp-idf\components` directory, typically in | ||
| `C:\Users\%username%\esp\esp-idf\components` or `C:\Users\%username%\Desktop\esp-idf\components`. | ||
| Be sure to run the `ESP-IDY X.Y CMD` command prompt that has `%IDF_PATH%` defined. | ||
|
|
||
|
|
||
| ``` | ||
| cd \workspace\ | ||
| git clone https://github.com/wolfSSL/wolfssl.git | ||
| cd wolfssl\IDE\Espressif\ESP-IDF\ | ||
| .\setup_win.bat | ||
| ``` | ||
|
|
||
| # Tips | ||
|
|
||
| If JTAG gets into a mode where it is simply always returning an error (app continually resetting) | ||
| try using serial port to program a basic, operational ["hello world"](./ESP32-hello-world/README.md). | ||
| The Arduino IDE or command-line ESP-IDF can be handy here. | ||
