[Bug Report] Fails to establish TPM connection

[emilm]

Context

• OS, version, SKU and CPU architecture used: yocto kirkstone with kernel 5.15, arm32v7
• Application's .NET Target Framework : 6.0
• Device: Raspberry PI3
• SDK version used: Microsoft.Azure.Devices.Provisioning.Security.Tpm Version 1.15.0-preview-00

Description of the issue

Fails to acquire TPM device. It worked before but I have upgraded OS and kernel etc so it might be that or the container image being too old. I am not sure where that response comes from, whether it's a generic error or if the return codes have changed or at what level.

I use cr.microsoft.com/dotnet/runtime:6.0.15-bullseye-slim-arm32v7.
With packages:
libtss2-tcti-tabrmd-dev
tpm2-tools
tpm2-abrmd \

Host OS has :
tpm2-tss 3.2.2
tpm2-tools 5.2
tpm2-abrmd 2.4.1

Code sample exhibiting the issue

using var secProvTpm = new SecurityProviderTpmHsm(deviceId);
var authenticationMethod = new DeviceAuthenticationWithTpm(deviceId, secProvTpm);
_logger.LogInformation("Creating Device Client with TPM");
deviceClient = DeviceClient.Create(iotHubHostName, authenticationMethod, Util.GetTransportTypeFromEnvironment());

Console log of the issue

`Closing TCTI conn
TCTI conn closed!

AbrmdWrapper: Unmarshaled TctiProvInfo

I upgraded to mcr.microsoft.com/dotnet/runtime:6.0.27-bookworm-slim-arm32v7 in the container and the error disappeared but the process natively crashes:
