Hi Team,

We’re using the MCU Boot for the RA4M2 Evaluation board from the suggested Photo –EK_RA4M2_MCUBoot_BL.

The project gets stuck at the stage- Verify the boot image and get its position.

Below is the error observed while executing the design.

Below is the storage allocation for different sectors-

Kindly, suggest a resolution for the same.

Thanks and Regards,

    Hello,

    When the RA4M2 MCU boot process stops at the “Verify boot image” stage, it indicates that the microcontroller is unable to successfully verify the integrity of the boot image being loaded.

    Here are a few possible reasons and troubleshooting steps to resolve the issue:

    • Incorrect boot image
    • Corrupted boot image
    • Memory or address configuration
    • Security settings
    • Debugging and logging
    • Consult documentation and support

    It’s important to note that the exact steps and solutions may vary depending on the specific development environment, tools, and firmware used. Therefore, consulting the relevant documentation and seeking manufacturer support is highly recommended to resolve the “Verify boot image” issue with the RA4M2 MCU.

    Thank You

    Ashish

Hi,

I have a RA4M2 eval kit and am working on a product for that MCU. From what I can see the USB example code provided for this MCU uses FreeRTOS, with the USB send and admit running in its own thread.

I believe my product doesn’t need an RTOS. Would it be possible to use the RA4M2 USB drivers without any RTOS, with the send and receive running in a circle in the main thread? Would there be any example code for this?

Thanks,

Vikas

    Hello,

    The Renesas RA4M2 microcontroller has built-in USB functionality and comes with a USB driver library that can be used to develop USB applications without an RTOS. Here are the general steps to use the RA4M2 USB drivers without an RTOS:

    • Download and install the Renesas e2 studio IDE and the RA4M2 USB driver library.
    • Create a new project in e2 studio for your RA4M2 microcontroller.
    • Include the necessary USB driver library headers in your project.
    • Configure the USB module on your RA4M2 microcontroller by setting the appropriate registers.
    • Call the USB driver initialization function to initialize the USB module.
    • Implement your USB application code, such as handling USB requests and transferring data to and from the USB device.
    • Build your project and download the firmware to your RA4M2 microcontroller.
    • Connect your RA4M2 microcontroller to a USB host device and test your application.

    Thank You

Dear Volt Team,

We’ve some questions related to the product/ manufacturing of custom boards using RA4M2 MCU.

1. Is multiple boards flashing at a time supported? If yes, please share the documents for the tools and configuration.

2. How do we handle the MD pin in case of multiple board flashing, without manual intervention?

Regards & Thanks,

AG

    Hello Ashish,

    Thanks for sharing your question with Volt.Tech Engineering Community!
    Yes, you can program multiple devices with Renesas Flash Programmer. For Renesas Flash Programmer’s latest performances from V3.05.00 or later you can create a single design and specify the serial number of each emulator( E1 emulator/ E2/ E2 Lite) in the tool option when starting RFP via command.

    You can find all the necessary tools, manuals, and documents.
    https//www.renesas.com/us/en/software-tool/renesas-flash-programmer-programming-gui#overview

    As far as it concerns the MD pin then’s the suggested connection from the RA4M2 hardware manual for JTAG, SWD, and Serial Programming


    Generally, this pin should be high in debug mode and low when programming the device( flashing).
    Then there’s a different manual for e2 programmers.

    https//www.renesas.com/document/man/e2-emulator-e2-emulator-lite-additional-document-users-manual-notes-connection-ra-devices-0
    And let us know!

    Kind Regards,

I’m using RA4M2AD3CFP. I generated raw binary from e2 stdio and loaded to board using Seggar J- Flash Lite, the file was programmed successfully. But after this my MCU isn’t working correctly, I’m not able to load another binary, incapable to debug, unable to do full chip wipe out also. I tried with RFP V3.10 and also Seggar J- Flash Lite. My development is fully stopped due to this issue. Please help me recover my board.

    1. try Address range "0x20000000 0x2000" 2. try 'Terminal 0' instead of 'All Terminal' 3. close Rtt viewer , reconnect debugger and try open it again 4. if you have two boards , open the logs for another board and than the one with yours
