hello benjamin.deuker,
back to your comment #13. are those steps executed on a non-fused target?
what’s the test results with native ubuntu environment?
Hello JerryChang,
Yes
Exactly the same result.

hello benjamin.deuker,
I’ve tested with Xavier NX eMMC, which fused with SBKPKC, it’s able to flash and boot-up correctly.
what’s your SBK keys looks like? the SBK key consists of four 32-bit words stored in a file in big-endian hexadecimal format.
for example,
$ cat sbk.key
0x12345678 0x9abcdef0 0xfedcba98 0x76543210
Hello JerryChang,
With the JetPack 4.4 version, I had an error on the format of my SBC key file.
So I had created a new file skb_file_flash.key such as :
cat sbk_file_flash.key
0x12345678 0x9abcdef0 0xfedcba98 0x76543210
So I tried to use this file to flash with JetPack 4.6.2,
but it didn’t work.

hello benjamin.deuker,
BTW,
we’ve also test fuse burning with -p to enable production mode.
let me double confirm this…
you’ve fuse and image flash complete, but device cannot boot-up, it stucks before MB1?
Yes, the fuse and image flashing were completed, but the loading and validation of the MB1 BCT failed, because the card was in recovery mode, as mentioned in paragraph “Microboot 1”.
After activation of the production mode :
sudo ./odmfuse.sh -i 0x19 -p -k /home/citix-ai/Credential_Keys/rsa_priv.pem -S /home/citix-ai/Credential_Keys/skb_file.key jetson-xavier-nx-devkit-emmc
The boot was successful.
Thanks a lot
Regards
