Hi All,


Refer to ERR007926 in IMX6DQCE(Rev.6).

There is below description in SDMMC boot Workaround.

"SD/MMC: Choose an SD/MMC card for which the Nac parameter is to be specified less than

50 ms and its initialization time is less than 500 ms."


I think that Nac parameter is TAAC + NSAC from SD Specification.

But, I didn't find the parameter of "initialization time".

Could you tell me the parameter?


Best Regards,
