Dear NXP team.

I have a question about DDR Memory Map default config.

I got the answer from the bellow link.

DDR Memory Map default config value for TZASC

But

141459_141459.pngpastedImage_8.png

the OCOPT_CFG valuses are :  

- OCOTP_CFG3 : 0x00620302

bit2322212019181716
values01100010

then i think DDR Memmory Map default config bit[21:20] is 10(4kb interleaving Enabled).

but i got an answer from nxp team. it's Single DDR channel...

could you let me know why?

Best regards,

MyungJin Hwang

Hello Yuri.

Thanks for the reply...

then one more question.

How to find or know that BOOT_CFG[3] relates to OCOTP_CFG4?

is there some table info?

Have a great day,

Hello,

To be oriented how register OCOTP_CFGx correspond to the fuses ,

please use column “Addr” in tables of Chapter 5 (Fusemap) and

column “Absolute address (hex)” in table in section 46.5 (OCOTP Memory
Map/Register Definition) of the i.MX6 D/Q RM.
  For example, value of OTP Bank0 Word0 (Lock controls) (OCOTP_LOCK)

at 0x021B_C400 corresponds to Table 5-2. (Lock Fuses) with 0x400 offset.

Regards,

Yuri.

Hello,

  The BOOT_CFG[3] relates to OTP Bank 0, word 5 : that is, bits 23-16 of

OCOTP_CFG4 should be used. 

Have a great day,
Yuri
