[ECOS] 82559 Self Test failure

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

Hi all,

I can't get the code for the Xscale platform to pass through the Self Test 
defined
in the function i82559_init(). Did anybody have the same problem. There is 
not much
documentation about it and conseguently there is not much I can do for 
pinpointing what's wrong.

Here is the code sequence which is failing:

#ifdef DEBUG
   os_printf("Init82559 %d @ %x\n82559 SelTest\n",
             p_i82559->index, (int)ndp);
#endif

   ints = Mask82559Interrupt(p_i82559);

   // Reset device
   i82559_reset(p_i82559);

   // Perform a system self-test. (get enough mem to round address)
   if ( (selftest = (cyg_uint32)pciwindow_mem_alloc(32) ) == 0)
       return (0);
   p_selftest = (cyg_uint32 *) ((selftest + 15) & ~0xf);
   p_selftest[0] = p_selftest[1] = -1;

   OUTL( (VIRT_TO_BUS(p_selftest)) | I82559_SELFTEST, ioaddr + SCBPort);
   //count = 0x7FFFF;                // Timeout for self-test.
   count = 0x0FFFF;                // Timeout for self-test.

   do {
       udelay(10);
   } while ( (p_selftest[1] == -1)  &&  (--count >= 0) );

   // Reset device again after selftest
   i82559_reset(p_i82559);

   Acknowledge82559Interrupt(p_i82559);
   UnMask82559Interrupt(p_i82559, ints );

   if (count < 0) {
       // Test timed out.
#ifdef DEBUG
       os_printf("Self test failed\n");
#endif
       return (0);
   }
The counter is timing out and the function returns at this point.

Thanks,
Cristiano.
