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,
    Vikas Nagpal

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
