LX2160A get MP key failed

Hi NXP,

We are building LX2160A secure boot system based on LLDP and verifying MP key function.

Install and start up the secure boot system on our LX2160A board are OK and so we think ITS bit value is 1, but get "Device is not initiated" error after execute "mp_app -p" command.

Do you have any advice to check this issue ?


Thank you,

Did customer follow LLDP document section 6.4.4?

Such as

  1. Run tee-supplicant & command from the Linux prompt.
  2. Depending on the Linux kernel version used insmod securekeydev.ko from right folder

Please also let customer enable kernel printk when run 'mp_app', and share their log.

echo 8 > /proc/sys/kernel/printk

dmesg
