I am using IMX 6Dual Lite processor (MCIMX6U8DVM10AB) and
EMMC 4.51 (MT29PZZZ8D5BKFTF-18 W.95L). The clock(400Khz) is fine from the
processor, but after issuing CMD1 the Present Status Register
(uSDHCx_PRES_STATE) of IMX6DL shows CIHB as 1 which means CMD line of eMMC is
busy and any further commands to the e-MMC will be ignored and it shows
"CMD1 Fail" .I believe, one of the reasons for no response from the
device is incompatible voltage range, but both emmc and the processor are set
Your inputs for this situation would be very helpful.
