This will print more information about the MCI card detection. Maybe it helps. Check also: - pin multiplexing - power supply to the SD card - GPIOs for detecting the SD card (some kind of inserting signal) - increase the min frequency to about 400 kHz. Maybe 1476 Hz are too slow and conflict with some timeout values Regards, Juergen -- Pengutronix e.K. | Juergen Beisert | Linux Solutions for Science and Industry | http://www.pengutronix.de/ | _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
