Hi Yuri,

I was wondering if you could tell me how to do these:
1. How to check the SD/MMC manufacture mode is enabled or not? 

2. How can I read the value of this bit "Disable SDMMC Manufacture mode" on u-boot?

    md 0x470 1?

Hello,

   by default SD/MMC Manufacture Mode is enabled. 

For access to the fuses - base address i.MX 6ULL OCOTP is 0x021B_C000.

So, 0x021B_C470 may be used for read.

Have a great day,
Yuri
