Dear all,

Would you teach about DCD header version?

I referred to the flash_header.S in Linux BSP.
The version of DCD is 0x40.

"dcd_hdr:          .word 0x40E002D2 /* Tag=0xD2, Len=90*8 + 4 + 4, Ver=0x40 */"


However, in Table 8-31 "DCD Header" of a reference manual, version is 0x41.

"Version: A single byte field set to 0x41"


Do I need to be careful of this difference?

May I have advice?

Best Regards,

  Really i.MX6 is one of HAB 4.1, the mentions about ver. 4.0 are derivative

from i.MX53 and do not influence on HAB functionality. One of main differences

between the ver. 4.1 and ver. 4.0 is ability for the rev. 4.1 to support Encrypted

Boot by ROM. 


Have a great day,
Yuri
