Hi everyone,
I need to store user unique id to iMX6 board and i know that write to OTP register helps me solve this issue.
I want to use HW_OCOTP_MISC_CONF to do this.
My questions are:
1/ What is the purpose of HW_OCOTP_MISC_CONF register on iMX6? When i use HW_OCOTP_MISC_CONF to store my id, Do any problems affect operation of iMX6 board?
2/ Does it have another OTP register which helps me write user id??
Thank you so much and Best regard!
Dang

Hi,
As for "free" fuses, please refer to Chapter 5 (Fusemap) of the Reference Manual.
Customers can apply to OEM fields (if not used as SJC_RESP and MAC_ADDR); also GP1, GP2
fuses may be mentioned here. SRK_HASH is intended for HAB application, if there is no need for HAB,
SRK_HASH also may be considered. But – strictly speaking – NXP does not guarantee that some of these
fuses (as GP) cannot be used by software (boot ROM, OS).
Regards,
Yuri.
Hello,
HW_OCOTP_MISC_CONF relates to PAD_SETTINGS fuse ; please refer to
Chapter 5 (Fusemap) of the i.MX6 D/Q RM. This field is used to configure IO pads
settings for boot. So, when burned, this may affect booting.
Have a great day,
Yuri

Thanks Yuri,
Because HW_OCOTP_MISC_CONF affects booting so can i use HW_OCOTP_MAC0 and HW_OCOTP_MAC1 to write my id? Also Chapter 5(Fusemap), i see that MAC_ADD is reserved for customers/software.
Best regard!
