Background/SW Versions:
Processor: TI AM5728
Platform: TI AM572x EVM
Processor SDK: ti-processor-sdk-linux-am57xx-evm-02.00.02.11
Linux Kernel: Using the 4.1.18 kernel included with the Processor SDK above
IPC: Using pre-built IPC binaries (both libraries and LAD) from the Processor SDK above

Problem:
I'm in the process of trying to get ARM-DSP MessageQ communication working. Similar to the thread referenced above, doing a simple IPC_start() leads to some issues as observed from the LAD log file. In my case, I apparently get passed the NameServer_setup processing but run into the same "Address family not supported by protocol" errors later, during NameServer_attach.
Unlike the thread above, I didn't build IPC - I'm using the provided binaries from the Processor SDK. I did rebuild the kernel but only with minor tweaks to the configuration provided for the AM572x EVM. So, I would assume that everything is matched up (IPC/Linux Kernel-wise) as desired.
Please see the LAD log output below; any ideas?
