Hi, It comes some problem when I used nvftpm_helper-app -g command in Jetson Orin Nano.
It shows Segmentation fault (core dumped).
Is that mean I didn’t flash the board propertily?

hello ncuwchenyx,
it should be… /usr/sbin/nvftpm-helper-app, did you have customize the app?
please also share the complete logs for reference.
No, I didn’t customize the app.
There is just one error message in the log
I tried all TAs in the /usr/sbin/ , and their logs are same as nvftpm_helper-app.
I think there are some problem when I copy the files from /public_srcs/Linux_for_Tegra/source/src_out/optee_src_build/optee/install/t234/ to the target board(/lib,/bin,/usr ).
hello ncuwchenyx,
could you please refer to Verifying the fTPM EKs by running with verify script.
Hi Jerry,
Because I don’t have the FSKP package in the tutorial, can I just skip this step(generating fuseblobs)?
hello ncuwchenyx,
please give it a try to test with verify script, thanks
hello ncuwchenyx,
FYI, OPTEE CA must be run at root privilege, for instance, $ sudo nvftpm-helper-app -g
besides, the fTPM CA can only work on a fTPM provisioned device.
all the internal functional would be disabled on a non-fTPM provisioned device.
Hi Jerry,
The device I am using is a Jetson Orin Nano with Jetson Linux 36.4.
Is it an fTPM-provisioned device?
Furthermore, does the result of sudo nvftpm-helper-app -g indicate that this is not an fTPM-provisioned device?
hello ncuwchenyx,
a fTPM-provisioned device it means a device should be fused with PKC+SBK.
a device it should also fused with fTPM related fuses, and the EKB has fTPM related properties.
please check Firmware TPM section, you may refer to Secure Boot section as well.
