[prateek22]

I want to disable JTAG from u-boot without using imx-otp application.

Can you please confirm below command will disable JTAG in imx6q processor :

fuse prog 0 6 0x100000

Let me know if you know any more details.

Hello,

Yes, that is correct.

0x460[20] (SJC_DISABLE) corresponds to Value of OTP Bank0 Word6 (Configuration and Manufacturing Info.) (OCOTP_CFG5) and that value is configuring:

1 - Secure JTAG Controller is disabled.

Best regards.
