Hello everyone,

I make a new RA2E2 hardware board. But it can’t start up flash programmer connect fail with SCI, and SWD connect fail too.

I check some pins

VCC3.3 V

VCL1.5 V

P201/ MD can switch 0V or 3.3 V with key.

RES can switch 0 V or3.3 V with key.

timing is right when PC send data to RA2E2 board.

But RA2E2 have no any response.

Are there any other debug way for RA2E2? or any user guide doc for this issue?

Thanks.

    Hello, Are you testing to connect with Renesas Flash Programmer? What debugger are you applying? Please check the E2/E2 Lite recommended connections for SWD: For VCL pin: The MD pin should be high to enter debugging mode and low to enter serial programming mode via SCI: The RES pin should be connectRead more

    Hello,
    Are you testing to connect with Renesas Flash Programmer? What debugger are you applying?
    Please check the E2/E2 Lite recommended connections for SWD:

    For VCL pin:

    The MD pin should be high to enter debugging mode and low to enter serial programming mode via SCI:

    The RES pin should be connected to pull- up.
    Best & Regards

Hello, How reliable is the data flash (using FSP VEE module) in case of interrupting power supply during write/erase operation?

    Hi, However, it seems that if 2 consecutive power interrupts during write operations occur, the data aren't copied again after the second power interrupt, If I understand your concern right. So the VEEPROM has no valid data in this case. I hope it helps. Thank You
