Hi all, I reading the DCD section of iMX6ULL datasheet.The DCD version is a fixed value 0x41.And I build the uboot.imx through the config "mx6ull_14x14_evk_nand_defconfig".Then I use hexdum to view that file.Blew is content of uboot.imx file.

The 0x2C address store the DCD header, 0xD201E840.The datasheet describe the version is set to 0x41.While this file is 0x40.Does it right? My datasheet version is  "Rev. 1, 11/2017".

I checked other uboot.imx and they have the same value so seems this is right.

Thanks for your reply! I had checked the value of prebuilt binary from mfgtools and they are same with 0x40.

I haven't any other problem.
