hello ilies.chergui,
it’s necessary that you must enable secureBoot for Xavier to program all fuse (PKC, SBK, KEK…etc) at once, in addition to make the “SecurityMode” enabled. (i.e. -p option of odmfuse.sh)
let’s check your Boot Rom communication failed first,
are you able to prints UID of chip as below. i.e. $OUT/Linux_for_Tegra/bootloader/tegrarcm_v2 --uid
for a clean board, the first nibble of BR_CID is expected to be 8.
