Herbert, I attached a list of tested SD cards for MPA 2.0. MC3100 is on of the product that based on this platform.

Yoshi, MC3100 doesnt have micro SD card format like MC75A and MC95 so that is why i specifically asked for tested and validated on MC3100 for SD card format SanDisk Ultra-II Non-Industrial 32GB Memory Card (SDSDRH-032G-A11)  SD card Kingston 32GB SD card (SD4/32GB)   SD card both these cards are marked or future testing in the excel sheet ?
