1. In most cases there are need to sold additional pullup resistor 10kOhm between MCI_CMD and Vcc. Without this resistor SD card will be non-accessible for software like linux kernel. (Source: Errata from Atmel).
PS: on EmQbit this trouble *PARTIALLY* solved via patch, which enable internal pull-up resistor. \\wbr Vitaly Chernookiy _______________________________________________ ARMedslack mailing list [email protected] http://lists.armedslack.org/mailman/listinfo/armedslack
