I met a problem when connecting ACU with IIM module in memory pipe, I got an error " Failed to connect IIM0 and ACU modules 0x00000021" which indicates "If trying to destroy a configuration in use?". My data flow is IPF1 outport0 interfaces with inport0 and inport1 of ACU, to get square value of IPF1 outputs, then ACU outputs to IIM0 to get integral value, then output the value from OPF3. I tried IPF1->ACU->OPF3 and IPF1->IIM0->OPF3 with the same configuration, all work well, however when I assemble the code together, there is an error when ACU connecting with IIM0. I also attached my code here, could you help to take a look and indicate the cause? Thanks in advance.
