There are contradictory descriptions in an app note and in the l4t doc. So, what is the correct value of pkc_disable for PKC? NVIDIA Jetson Nano Fuse Specification [スクリーンショット 2020-04-04 7.49.22] L4T Doc Fuses and Security [スクリーンショット 2020-04-04 8.19.10]

Hi, We have clarified it and here is the correct value: | 1| pkc_disable | PKC - 0x0, NS - 0x1 | For enabling secureboot, please burn all fuses with -p in one step. Such as: $ sudo ./odmfuse.sh -i 0x21 -c PKC -p -k …/emi_pkc.pem -o 0x0000000000000000000000000000000…

[image] And in the README_secureboot.txt located in the bootloader folder the default values are: PKC - 0x1, NS - 0x1 (T210) which is not equal with : L4T Doc PKC: 0x01 (T194) NS: 0x00 (T210) Fuses and Security

Thanks for the confirmation. [image] DaneLLL: please burn all fuses with -p in one step. OK, will do.

Hi Dane, I ran this command, but I did it as such: sudo ./odmfuse.sh -i 0x21 -c PKC -p -k ~/rsa_priv.pem -o 0x1234567812345678123456781234567812345678123456781234567812345678 Which resulted in my pkc_disable fuse being set to 0x1… Are some of the 256 user-definable fuses shared with pkc_disabl…

What is the correct value of pkc_disable for PKC?
