Hi @JerryChang
Could you please explain what happen here ?
[0005.673] C> LOADER: mb1bct binary ratchet level 0 is less than ratchet level 60 from HW fuses.
[0005.682] C> LOADER: Could not read mb1bct.
[0005.686] C> Fail to load mb1-bct bin
[0005.689] C> OEM authentication of MB1-BCT failed!!!
[0005.694] E> NV3P_SERVER: Failed to verify image bct_mb1.
I saw in the documentation that Nvidia introduce improvements in security MB1 Platform Configuration → OEM-FW Ratchet Configuration .
Pease take a look here
I can’t find the folder t19x/<platform>/bct/ratchet in the BSP tarball or in the Jetpack 4.4 L4T R32.4.3
Could you please confirm that ?
Best regards,
Ilies
