I'm working with kinetis k60 and I'm develomping an application that uses an sd card by spi. I check the sd card presence, but I'd like evalute if sd card is working correctly or Not. I want to do this because sometimes when I turn on the device, the sd card is locked and it is impossibile to comunicate with it unti I cut its power supply. Does someone help me?
Many thanks in advance for your support.
