Getting started with MicroPython on the Renesas RA
|
|
==================================================
|
|
|
|
This tutorial will guide you through setting up MicroPython,
|
|
getting a prompt, using the hardware peripherals, using internal
|
|
flash file system, reset and boot modes, and Factory reset the
|
|
internal file system.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
You need a board. For the information of available boards,
|
|
please refer to the general information about Renesas RA port: :ref:`renesas-ra_general`.
|
|
|
|
You need a USB-Serial conversion cable to connect the board and your PC.
|
|
Please get a type with separate signal pins so that you can connect to
|
|
the UART TX and RX pins on the board.
|
|
|
|
Flashing the MicroPython image with J-Link OB
|
|
---------------------------------------------
|
|
|
|
The board has a builtin programmer interface called J-Link OB.
|
|
Using the J-Link Software, you can flash the binary image "firmware.hex"
|
|
of MicroPython on the board via J-Link OB.
|
|
|
|
You can download the J-Link Software and Documentation pack from https://www.segger.com/downloads/jlink/.
|
|
|
|
After installing J-Link Software, start J-Flash-Lite program. Then specify following device in Device select menu in J-Flash-Lite.

Access the MicroPython REPL (the Python prompt) via USB serial or UART with 115200 baud rate, 1 stop bit and no parity bit using your favorite terminal software, picocom on Linux or Tera Term on Windows. You can try on Linux::
|
|
|
|
$ picocom /dev/ttyACM0
|
|
|
|
You can see the MicroPython REPL prompt like below::
