[Discuss OpenCPI] Fwd: Fwd: Fwd: Multiple AD9361 Devices Cause Multiple Connections Error

Some debugging help: I often use make -n in these scenarios, which will
print to the screen the ocpigen commands being run - except in this case
where -n doesn't work, so I mod'd ocpigen to print out its arguments - then
stepped through the ocpigen command with gdb. The ocpigen command can also
be called w/ OCPI_LOG_LEVEL set to 8 or 10, which gives useful logging info.

There are lots of ordinals being handled here, in part to facilitate the
multi device<->subdevice worker scenario. One problem I have identified is
an incorrect ordinal inspection - I *think* this is the fix:

diff --git a/tools/ocpigen/src/hdl-config.cxx
b/tools/ocpigen/src/hdl-config.cxx
index bc0cfa5..d3412ff 100644
--- a/tools/ocpigen/src/hdl-config.cxx
+++ b/tools/ocpigen/src/hdl-config.cxx
_at_@ -327,7 +327,8 @@ emitSubdeviceConnections(std::string &assy,
 DevInstances *baseInstances) {
          // If there are no mapping entries, then we use the implicit
ordinal of the
          // supports element among supports elements for that device type
          if (s.m_supportsMap.empty()) {
- if (si->m_ordinal != d.m_ordinal)
+ //if (si->m_ordinal != d.m_ordinal)
+ if (s.m_ordinal != d.m_ordinal)
              continue;
          } else {
            auto it =

This suspected fix causes other problems that I'm still looking into.

Thank you. I appreciate the help.

Let me know if you want me to try anything or give you any other
information regarding my setup.

Thanks,
Brian
