Xavier NX with JetPack4.5.1 Fuse issue

We use Xavier NX develop our product.
When production we will write some data into fuse, such as below
Device ID: X0D000NX
secure key: “0x54888a15 0x1acba63b 0x3c5819aa 0xb14745b9 0xd4b97d77”
pkc file: fake-pkc-nx.pem
and also download secureboot_R32.4.3_aarch64 related file to Linux_for_Tegra.

When we use JetPack4.5.1 and burn fuse will cause device restart no any screen output. but use JetPack 4.4.1, 4.4 and 4.3 and burn flash will work properly after restart. Burn fuse operation as below. Is there any one can help to check?

hello seanl1,

please check L4T | NVIDIA Developer and download the latest SecureBoot package,
for example, secureboot_R32.5.0_aarch64.tbz2.
