[tpm2] Re: Help - how to store a certificate in the NV under the platform hierarchy?

hmm, interesting...

I tried the same command on a RPI4 with a physical TPM (Infineon SLB9670)... and it worked.

tpm2_nvdefine 0x01C90000 -C p -s 898 -a "ppread|ppwrite|platformcreate"

and this is what I get:
nv-index: 0x1c90000

Maybe, as you commented, it could be a specific issue of the ibm swtpm (v1661).

I'll keep on working on both (swtpm and rpi4/slb9670)

Thanks!
