In the version of the pulp_soc pointed by the master branch of control_pulp, the port test_i of the axi_to_mem_interleaved_intf module is unconnected (line 175 of soc_interconnect_wrap.sv).
The bug seems to come from the axi_to_mem_interleaved_intf (axi_to_mem_interleaved.sv) itself since the port test_i is not declared and there's the missing connection in the instance of axi_to_mem_interleaved within the module axi_to_mem_interleaved_intf.
The bug in this AXI IP has been solved in v0.39.2 release of the axi submodule.
