hello ndy83107,

just create a file to assign the keys, the file content is maintain by yourself, then you should covert the file into xml file.
for example,

$ cat sbk.xml
0x123456789abcdef0fedcba9876543210

note, the documentation you’ve point-out is based-on r32.3, which is quite old release version.
please check https://developer.nvidia.com/embedded/linux-tegra for the latest NVIDIA® Jetson™ Linux Driver Package. it’s now r32.6.1

hello ndy83107,

just double confirm you’re working on the L4T release version with the same version secureboot package.
for example,
if you’re based-on L4T, r32.6.1 release, please also take the secureboot_r32.6.1_aarch64.tbz2 for the deployment.
thanks
