| Overview |
| ======== |
| The Hello World demo application provides a sanity check for the new SDK build environments and board bring up. The Hello |
| World demo prints the "Hello World" string to the terminal using the SDK UART drivers. The purpose of this demo is to |
| show how to use the UART, and to provide a simple project for debugging and further development. |
| |
| Toolchain supported |
| =================== |
| - GCC RISC-V Embedded 7.1.1 |
| - RISC-V Eclipse IDE 4.7.2 |
| |
| Hardware requirements |
| ===================== |
| - Mini/micro USB cable |
| - RV32M1-VEGA board |
| - Personal Computer |
| |
| Board settings |
| ============== |
| No special settings are required. |
| If download M0+ core project, need to let MCU boot from M0+ core, please follow below steps: |
| 1. Download blhost.exe from www.nxp.com/kboot. |
| 2. Connect J8 on board to PC using USB cable. |
| 3. After PC recognize the USB HID device, go to blhost.exe folder, open command line. |
| 4. Run command "blhost.exe -u -- flash-erase-all-unsecure", it will erase the flash on chip. |
| 5. Run command "blhost.exe -u -- flash-program-once 0x84 4 ffffffbf", set FOPT3 to boot from M0+ core. |
| |
| Prepare the Demo |
| ================ |
| 1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board. |
| 2. Open a serial terminal with the following settings: |
| - 115200 baud rate |
| - 8 data bits |
| - No parity |
| - One stop bit |
| - No flow control |
| 3. Download the program to the target board. |
| 4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo. |
| |
| Running the demo |
| ================ |
| The log below shows the output of the hello world demo in the terminal window: |
