Hello Team

I am trying to use tpm2_import on a Big Endian 32 Bit platform and running
into following error:

--------------------------------------------------------------------------------------------------------------------------------

*Command: *

   1.

   openssl genrsa -out private.pem 2048
   2. tpm2_import -C 0x81000001 -G rsa -i private.pem -u key.pub -r key.priv


*Error:*
ERROR:esys:src/tss2-esys/api/Esys_Import.c:110:Esys_Import() Esys Finish
ErrorCode (0x000003df)
ERROR: Esys_HMAC(0x3DF) - tpm:parameter(3):integrity check failed
ERROR: Unable to run tpm2_import
--------------------------------------------------------------------------------------------------------------------------------


Need pointers to debug this issue.
Have any of you come across this error with tpm2_import on Big Endian 32
Bit Platform? Do we have a fix Or can you provide inputs on the source
where I can look at for further debugging?

Thanks
Raj
