Disable JTAG in IMX6 board

[nagarjun_n]

Hi,

I have read the document http://cache.freescale.com/files/32bit/doc/app_note/AN4686.pdf 

For disabling JTAG permanently we need to make set this OTP SJC_DISABLE.

I found commands like  "fuse  prog  0  6  0x100000", but this will work in uboot.

I need a command to disable the JTAG after application startup.

Is /sys/fsl_otp/HW_OCOTP_CFG5 OTP is the one ??

What value we need to fuse ?

is echo 0x100000 > /sys/fsl_otp/HW_OCOTP_CFG5 is same as fuse  prog  0  6  0x100000 ??

Can anyone help me on this.
