Hi , everyone
I get an amazing problem about the interface of SD card in dm355. In the plug of SD card of dm355 in EVM, the pin of 10 and 12 are connected with msp430 I/O pins. Through the schematics I know the signal of pin 10 may indicates that the SD card is in write protection status and the signal of pin 12 may indicates that the sd card has been inserted or not.
Right now , we have redisigned the schematics and do not use msp430, so my problem is that whether the two status of pin 10 and pin 12 are checked by kernel or not? if we do not connect these two pins to dm355, dose the sd card work well?
