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.

https://www.nxp.com/docs/en/reference-manual/IMX6SLLRM.pdf

 

0 - Normal

1 - High

 

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

 

MMC

0x - High-speed mode

1x - Normal-speed mode

 

 

Which is correct ?
