Re: [ECOS] Still on ethernet configuration

["Cristiano Pereira" <ligieri2002 at hotmail dot com>]

Done. Now I'm using the latest CVS version. The problem persists unchanged. 
How will the "bt" command tell me whether the stack is corrupted or not?

Sometimes I have the impression that things are getting executed twice when 
I'm debugging. Look at this example:

Breakpoint 1, i82559_configure (p_i82559=0xc006994c, promisc=0, oversized=1,
   multicast_all=0)
   at
/opt/ecoscvs.10-13-2002/ecos/packages/devs/eth/intel/i82559/current/src/if_i82559.c:3180
3180        OUTL(VIRT_TO_BUS(p_i82559->rx_ring[0]), ioaddr + SCBPointer);
(gdb) n
340         HAL_WRITE_UINT16( io_address, (((value & 0xff) << 8) | ((value & 
0xff00) >> 8)) );
(gdb) n
3183        return 0;
(gdb) s
3180        OUTL(VIRT_TO_BUS(p_i82559->rx_ring[0]), ioaddr + SCBPointer);
(gdb) s
345         HAL_WRITE_UINT32( io_address,
(gdb) s
340         HAL_WRITE_UINT16( io_address, (((value & 0xff) << 8) | ((value & 
0xff00) >> 8)) );
(gdb) s
3183        return 0;
(gdb) bt
#0  i82559_configure (p_i82559=0xc006994c, promisc=393216, oversized=1,
   multicast_all=0)
   at 
/opt/ecoscvs.10-13-2002/ecos/packages/devs/eth/intel/i82559/current/src/if_i82559.c:3183
#1  0xc0021594 in i82559_start (sc=0xc0069fd4, enaddr=0xc50600 "",
   flags=-1073298004)
   at 
/opt/ecoscvs.10-13-2002/ecos/packages/devs/eth/intel/i82559/current/src/if_i82559.c:1619
#2  0xc011baf8 in stack ()
(gdb) s

I set a breakpoint in the function i82559_configure at line 3180. When
I step through it it seems to execute statements 3180 and 3183 twice.
Am I missing something silly or this is some sort of weird behavior
(I'm not very used to debug things using GDB so the question might be
silly)?

I'm also issuing the "bt" command but honestly I don't see how it tells me 
whether the stack is good or not. After the last "s" command
the program never returns.

Cristiano.
