I am working on imx6 dual lite board, I have programmed SRKH keys successfully by blowing fuses from kernel in /sys/fsl_otp.
Now, once board comes out of the factory or during production I wanted to disable serial boot using fuse register.
Hence, no one can connect OTG and flash uboot thorigh serial mode.
I know that BOOT_CFG4 is the right register to disable serial boot mode, but I don't know what value need to burn.
Also, I want to lock all the fuse register hence no one can rewrite again.
Could anyone please help me here.
Thanks in advance.
