According to "How-to enable HAB in i.MX6.pdf", I generate the u-boot-signed-pad.bin

 

Now, I need to burn the chip e-fuse to enable HAB boot.

  cd /sys/fsl_otp

  echo 0xxxxxxxxx > HW_OCOTP_SRK0

  echo 0xxxxxxxxx > HW_OCOTP_SRK1

  echo 0xxxxxxxxx > HW_OCOTP_SRK2

  echo 0xxxxxxxxx > HW_OCOTP_SRK3

  echo 0xxxxxxxxx > HW_OCOTP_SRK4

  echo 0xxxxxxxxx > HW_OCOTP_SRK5

  echo 0xxxxxxxxx > HW_OCOTP_SRK6

  echo 0xxxxxxxxx > HW_OCOTP_SRK7

 

  echo 0x00040000 > HW_OCOTP_MEM0

  echo 0x02 > HW_OCOTP_CFG5

 

However, when I exe the command:

cat /sys/fsl_otp/HW_OCOTP_MEM0

0xc0

 

What should I do about the HW_OCOTP_MEM0? 

I try to burn 0x00040000 to HW_OCOTP_MEM0, and I can't see anything in the console after reboot.
