Dear all,

tpm2_getcap -c 'handles-persistent' gives no output.

The below commands also doesnt give any output:

tpm2_getcap -c 'handles-loaded-session'

tpm2_getcap -c 'handles-saved-session'

tpm2_getcap -c 'handles-transient'

Pleas find details: TPM 2.0 device used - OPTIGA™ T PM SLB 9670 Processor - Qualcomm 8074 Arm64 Linux Kernel version - 5.4 tpm-tools version - 3.4.1 tpm-tss version - 2.0.1 tpm-aprmd version - 2.0.3

please do the needful at the earliest

If

tpm2_getcap -c 'handles-loaded-session'
tpm2_getcap -c 'handles-saved-session'
tpm2_getcap -c 'handles-transient'

then there are currently no loaded / saved / transient objects inside the TPM.
