Errors with `esmi_oob_tool` and EPYC Rome CPUs

Is it possible to run esmi_oob_tool with EPYC Rome CPUs? I'm trying to run esmi_oob_tool under OpenBMC on the ASPEED AST2500 in the AMD EthanolX CRB. esmi_oob_ex runs fine, but esmi_oob_tool fails on the last read_esb_boost_limit function:

I'm using Rome EPYC CPUs:

cpu family      : 23
model           : 49
model name      : AMD EPYC 7302 16-Core Processor

Just in case here is an output from the esmi_ib_library which looks fine and doesn't have any errors:
