I have ordered a SD Card booster pack to work with the CC3200 Launchpad, but the connector definitions do not match.. I was able to do some board modifications and make it to work with the CC3200 LAUNCHXL Rev 3.2. Here is the ECO List Scratch out traces at SJ1 , SJ2, SJ3, SJ4 Blue wire the following pins SD Card Pin No Header Pin 2 J2.3 5 J2.6 7 J2.7 The board looks as below now with the changes. And it works !!!
