hi all,

it’s due to UEFI variable protection feature is always enabled, you should provide UEFI variable authentication key in EKS image, otherwise UEFI will block the booting.

please follow the steps as below.

  1. Please visit jetson-linux-r3550 page to access the [Driver Package (BSP) Sources] package.
  2. Please extract op-tee tarball, and entering optee/samples/hwkey-agent/host/tool/gen_ekb
  3. IF you’ve OEM_K1 burned, please modify the script and replace the test OEM_K1 with your customize key.
  4. The contains a default UEFI variables authentication key (i.e. auth_t234.key). BTW, It is recommended that users use randomly generated auth_t234.key.
  5. Execute the script, and you’ll have a new EKS image, eks_t234.img.
  6. Please update EKS image accordingly, and re-flash the target. you may see-also Topic 270934 for steps to update EKS image.
