Hi, I have a question for boot config pins  for EMMC in i.MX6.

I want to confirm that BOOT_CFG4 is not used for EMMC, so I don't care those pins in boot time.

In reference schematics, those pins are all LOW status, but it has no problem to pull up them, is it right?

Thank you.

Hi JHY

I think you are right, except BOOT_CFG4[7] - OEM Infinite Loop Enable

it should be low (i.MX6DQ Reference Manual Table 8-2. Boot eFUSE Descriptions).

Best regards

Thank you, Igor.

I have one more question.

How about BOOT_CFG3[0] [1] [3]?

It is reserved pin and reference EVK has always low status.

Is it must be low in boot time for eMMC?
