RTOS/MSP432P401R: SD card - 30mA consumption

Thanks to google and someone who did the job:

Hello Amit,

Thank you for the help.

I have different cards but I would like to use a sandisc in the production. The 250uA would be perfect because right now I've got stack at 30mA consumption. I have also a tiny solar panel on the board and it charges the battery really well.

The main problem is that I already put the PCB in the preproduction phase(for testing few board) and I cannot access the SD card anymore to replace it. 
Right now I would like to save the 10PCBs that are ready to go in the production, later on I will switch to spi ram or put an switch for the SD.

So if you are so kind to let me know how can I shoot down the SD card I would be really grateful.

I'm attaching an image of an test board(not the current one) and the case... so you can see why I cannot change the SD card :D

Thank you for the help

unfortunately I cannot put the pins in high impedance state.

I've tried to manually config the CS(the latest drivers handles CS on their own..).

What I found out is that if I read something after I put the CS in the HI(deselect) the card goes to idle.
There are some solutions on the internet that you have to put 80clocks at the end to put the card in idle so it must be something.

really strange... 

Thank you for the help

If I understand correctly putting the PINS in the high impedance would mean that I reset the functionality of them.

Since the pins are configured like this:

*
 * NOTE: The SPI instances below can be used by the SD driver to communicate
 * with a SD card via SPI.  The 'defaultTxBufValue' fields below are set to 0xFF
 * to satisfy the SDSPI driver requirement.

    }
};

How can I change the state of the pins outside of the drivers? 

I will try to go deeper in the drivers, but the changes that I made right now(in theSDSPI.c) didn't affected the behaviour of the drivers. Should I compile the fat drivers separately? 

Thank you
