Hi,
We have verified the fuse process on r32.4.2. Host PC is Ubuntu 16.04. Target device is Xavier 32 GB.

  1. Set Xavier to recovery mode
  2. On host, execute fuse programming
$ sudo BOARDID=2888 FAB=400 BOARDSKU=0004 BOARDREV=K.0 ./odmfuse.sh --noburn -j -i 0x19 -c PKC -p -k rsa_priv.pem -S ./sbk.key --KEK2 ./kek2.key jetson-xavier
$ sudo tar xpf fuseblob.tbz2
$ cd bootloader
$ cat odmfuse_pkc.xml // check if required fuses are included
$ sudo ./fusecmd.sh
$ cd ../
  1. Set Xavier to recovery mode
  2. On host, execute flashing image
$ sudo BOARDID=2888 FAB=400 BOARDSKU=0004 BOARDREV=K.0 ./flash.sh --no-flash -u rsa_priv.pem -v ./sbk.key jetson-xavier mmcblk0p1
$ cd bootloader
$ sudo bash ./flashcmd.txt
