Power supply for RM48 development kit?

Saul A.

Hello,

This question is to people who have the RM48 "Hercules" development board (TMDXRM48HDK):

Is the power supply in your kit 5V or 12V?

I'm asking because I've just got the kit from a coworker with a 5V supply. He says that the board works "almost" fine, but per the documentation and label on the board itself it should be 12V.

Thanks in advance,

Saul

    Hello Saul,

    The board was designed to work with either a 5V or 12V supply. However, some daughter cards that are designed to work with the HDK would require a 12V supply. As an example, if you are using the FlexRay daughter card, a 12V supply is required because of the nature of FlexRay.

    However, I am curious about your comment that the board works "almost" fine with the 5V supply. If you could provide details on any issues you or your co-worker are seeing, we would certainly be willing to help you work through them and determine if this is a result of the 5V supply or if there is another issue with your board.

    Thank you for the quick reply, Chuck.

    The "almost" is a problem when this coworker tries to run a modified example program. He says that the instruction pointer starts from wrong location or like this. But the pre-built examples run fine. Nothing else is attached to the board besides of the USB to PC cable. So I tend to think this at least is not a hardware problem.

    Saul,

    I agree. This doesn't sound like a hardware issue. However, if you continue to have problems with it, let us know and we will be more than happy to help resolve it.
