SD card powering problems


I’ve been having problems powering a Kingston 4GB SD-card directly from the EMX module’s SD_PWR output. I’ve seen that other people have had similar problems and some solution have been posted how to fix this. My question is what happens if you connect SD card’s VCC directly to 3,3volts? If i understand correctly this SD_PWR output is taken straight from the NXP processor output and I’m worried that it can’t supply enough current for my SD card?

Where can I find schematics for the EMX module itself because the datasheet didn’t tell where this SD_PWR output comes from?

Connecting to 3.3V directly is not a bad idea and this is what we will be doing in future designs.
