you must also program the odm_production_mode, -p, once you program the fuse with PKC+SBK, otherwise, you’ll stuck at booting stage.
note, once odm_production_mode is fused with value of 0x1, all further fuse write requests are blocked and the fused values are available through the provided Tegra API.
thanks
may I know which authentication type, (for example, NS/ PKC/ SBKPKC) you’d enable for your Jetson platform?
you MUST determine the fuse types, (i.e. NS, PKC, PKCSBK) and burn those keys to the target for the 1st time.
due to safety concerns, you cannot have 2nd time fuse burning to program SBK into PKC fused device.
ya, that’s fuse commands to enable SBKPKC, please enable odmfuseread.sh to read the fuse info from the target board.
for example, ./odmfuseread.sh -i <chip_id> [options] target_board

USB communication failed.Check if device is in recovery
Same cable used to set in RCM and to flash with other devices, when in RCM, serial line doesn’t output anything as expected.
could you please try again by using --auth options, it’s following the authentication status of your board.
for example, $ sudo BOARDID=3310 BOARDSKU=1000 FAB=C04 ./odmfuse.sh --noburn -i 0x18 --auth SBKPKC -p -k <pkc> --KEK2 <kek2> -S <sbk> jetson-tx2-devkit
this is one offline approach to create fuseblob without boards connected,
please check whether you’re able to run this command-line correctly.
thanks

There is no update from you for a period, assuming this is not an issue any more.

hello TANGUY.MEZZANO,
actually, here’s failure for fuse burning.

may I which TX2 platform you’re using, please share the part#,
also, could you please share the xml file for reference.
