About custom boot loaders

This sample uses custom bootloader revision 5, and you can drag & drop the "xxxx_application.bin" file to write the program. Please see here for the detail.

How to write program

For GR-MANGO

When using DAPLink, please use xxxx.bin as following.

1. Connect the micro USB type B terminal to the PC using a USB cable.
2. You can find the MBED directory.
3. Drag & drop xxxx.bin to the MBED directory.
4. When writing is completed, press the reset button.

When using custom bootloader, please use xxxx_application.bin as following.

1. Connect the USB type C terminal to the PC using a USB cable.
2. Hold down USB0 and press the reset button.
3. You can find the GR-MANG directory.
4. Drag & drop xxxx_application.bin to the GR-MANGO directory.
5. When writing is completed, press the reset button.

Attention!
For the first time only, you need to write a custom bootloader using DAPLink.

For other boards

1. Connect the USB cable to the PC.
2. Hold down SW3 (USB0) and press the reset button. (Or turn on the power.)
3. You can find the MBED directory.
4. Drag & drop xxxx_application.bin to the MBED directory.
5. When writing is completed, press the reset button.

Attention!
For the first time only, you need to write a custom bootloader as following.

Development environment

You can use Mbed CLI (CUI) or Mbed Studio (GUI). Choose your preferred development environment.

When using Mbed CLI (CUI)

You can use GCC, Arm Compiler 5, Arm Compiler 6 and IAR. A license is required to use a compiler other than the GCC compiler.
Information of Mbed CLI that includes install&quick start guide is as the following.
Installation

How to import and build this sample

$ cd <projects directory>
$ mbed import https://github.com/d-kato/RZ_A2M_Mbed_samples
$ cd RZ_A2M_Mbed_samples
$ mbed compile -m <TARGET> -t GCC_ARM --profile debug

Set the following to <TARGET>.

• GR-MANGO beta version : GR_MANGO
• RZ/A2M Evaluation Board Kit :
  Serial flash boot (CPU board SW1-3 ON) : RZ_A2M_EVB
  HyperFlash boot (CPU board SW1-3 OFF) : RZ_A2M_EVB_HF
• SBEV-RZ/A2M : RZ_A2M_SBEV
• SEMB1402 : SEMB1402

See About custom boot loaders for program writing.
See How to debug using e2studio for debugging.

When using Mbed Studio (GUI)

You can use Arm Compiler 6 included with Mbed Studio for free.
Information of Mbed Studio that includes install&quick start guide is as the following.
Installation

Attention! : When using the GR-MANGO, select "Target" box to GR_MANGO. When using the RZ/A2M Evaluation Board Kit with HyperFlash boot, select "Target" box to RZ_A2M_EVB_HF.

Attention!
You can not debug using Mbed Studio. Use only for build purposes. Debug the elf file created by Mbed Studio using e2studio.

See How to debug using e2studio for debugging.

Terminal setting

If you want to confirm the serial communication the terminal soft on your PC, please specify the below values.
You can change the baud rate by platform.stio-baud-rate of mbed_app.json.

Baud rate	115,200
Data	8bit
Parity	none
Stop	1bit
Flow control	none

Attention!
SBEV-RZ/A2M and SEMB1402 use the RZ/A2M's USB as the terminal. To use USB for other purposes, delete OVERRIDE_CONSOLE_USBSERIAL macro in mbed_app.json file.

How to debug using e2studio

Download e2studio 7.4.0 or lator, and install. (Debugger : J-Link Base)
Connect the J-Link to your board.
