Hi all,


I'm plan to use i.MX6SLL with MMC and have a question about fusemap.


According to the following RM, BOOT_CFG1[3] is for selecting SD/MMC Speed in table 5-4.


0 - Normal

1 - High


On the other hand, in table 8-8, SD/MMC speed mode is as below.



0x - High-speed mode

1x - Normal-speed mode



Which is correct ?
