OpenSSL Provider with SE052F for RNG

We have a requirement to use the SE052F as a FIPS compliant source for random number generation. We require OpenSSL to use the SE052F, and in turn, all applications that use the openssl libraries to use the SE052F for RNG.

I understand we must use the NXP MW accessManager and the OpenSSL Provider.
I am using: SE-PLUG-TRUST-MW_04.07.01
I have followed the instructions in:
AN14028.pdf
SE-PLUG-TRUST-MW_04.07.01/simw-top/doc/hostlib/hostLib/accessManager/doc/accessManager.html
and the README info here (but not using this repo): https://github.com/NXPPlugNTrust/se05x-openssl-provider

accessManager built with the following cmake options:

NXP_SE_MW_CONF_OPTS += -DWithSharedLIB=OFF -DPTMW_Host=Raspbian -DPTMW_SMCOM=T1oI2C -DPTMW_Applet=SE05X_C \
	-DPTMW_FIPS=None -DPTMW_SE05X_Ver=07_02 -DPTMW_SE05X_Auth=PlatfSCP03 -DPTMW_SCP=SCP03_SSS -DSE05X_EN_PIN=582 -DSE_RESET_LOGIC=0 \
	-DPAHO_BUILD_SHARED=FALSE -DPAHO_BUILD_STATIC=TRUE

 

OpenSSL Provider built with the following cmake options:

NXP_SE_MW2_CONF_OPTS += -DWithSharedLIB=ON -DPTMW_HostCrypto=OPENSSL -DPTMW_Host=Raspbian -DPTMW_SMCOM=JRCP_V1_AM -DPTMW_SE05X_Auth=None

 

openssl.cnf modified as follows:

[provider_sect]
nxp_prov = nxp_sect
default = default_sect

[nxp_sect]
identity = nxp_prov
module = /usr/lib/libsssProvider.so
activate = 1

[default_sect]
activate = 1

 

The accessManager starts:

Starting accessManager (Rev.1.1).
  Protect Link between accessManager and SE: YES.
accessManager JRCPv1 (T1oI2C SE side)
******************************************************************************
Server: waiting for connections on port 8040.

RNG using openssl from the command line seems to work OK:

But, starting the ssh daemon fails:

I'd be very grateful for any help,
