about JTAG access in the secure JTAG mode of i.MX6UL

Dear all,

 

We want to use secure JTAG function of i.MX6UL.

However, we cannot access it by JTAG when i.MX6UL is secure JTAG mode.

 

We use Advice LUNA2 JTAG.

The challenge seems to succeed.

 

We set a register of the i.MX6UL following.

 

JTAG_SMOD = 0x01

SJC_DISABLE = 0

BOOT_CFG_LOCK = 0x1x

 

If there is more necessary setting for i.MX6UL, would you tell me?

 

 

May I have advice?

 

Best Regards,

Yuuki
