Unable to create TX buffer recovery queue

[Amalaye Oyake]

Setting MANAGERS=all may be one step but don't some of the

#define CONFIGURE_MAXIMUM_XYZs have default values of 0?

I may need to assign some values to these perhaps?

Have a look at the driver source, elnk.c, line 3525:

if (txDaemonTid == 0)
    {
       if( rtems_message_queue_create( rtems_build_name 
('X','L','c','r'),
                                       sc->numTxbuffers+1,
                                       sizeof(struct TXMD *),
                                       RTEMS_FIFO | RTEMS_LOCAL,
                                       &chainRecoveryQueue ) !=  
RTEMS_SUCCESSFUL )
       {
          rtems_panic( "etherlink : Unable to create TX buffer  
recovery queue\n" );
       }

...

i.e. the directive, rtems_message_queue_create( ), is failing...

I'm going to guess that you haven't included the Message Manager in  
your application's Makefile. If memory is not an issue (and 128 MB is  
*lots* to play with...), just set the "Managers" variable to "all":

i.e. in your Makefile set
MANAGERS=all

That will circumvent several obscure "gotchyaz"...
