Dear all:
I have purchased two cards one is TMDXEVM5505 ( C55xx ) main processor
card, and other is SpO2 daughter card.
I have checked all example programs on processor card (without
connecting SpO2 daughter card) e.g LCD, UART etc, The board is running
well.
But when i connect the daughter card and want to run any program (that was
running well on standalone card), it failed to run.
Any suggestion?
Thanx in advance

Can you clarify "failed to run"? There should be some LEDs on the EVM 5505 board that indicate boot status, do these
operate normally? Are you still able to connect CCS and download example programs?
Or does the EVM do nothing that you can see and appears to be dead?

Yes, it could be. Is there a signal or pin for the multiplex that you can check with a dig scope? If so this would
be a good thing to do -- see if the value changes when the Sp02 daughtercard is plugged in.
If that is the reason, then you can control the multiplex pin via software. Set for LCD when needed, set for SpO2
when needed.
