Atmel SD/MMC info error (report only)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If CONFIG_MCI_ATMEL=y and CONFIG_MCI_INFO=y, some useful info about the SD/MMC card can be displayed with "devinfo atmel_mci0". However, the parameter showing the number of bits used for transfers is incorrect. A SD card supporting 4 bit transfers is reported as using 2 bits. A logic analyzer shows that in fact all 4 bits are actually being used.
