Hi.
I found that the RTEMS ATA driver hangs
because it waits for READY_STAT to be asserted
after issuing a WIN_DIAGNOSE command.
In hw/ide.c we find
> case WIN_DIAGNOSE:
> ide_set_signature(s);
> s->status = 0x00; /* NOTE: READY is _not_ set */
> s->error = 0x01;
> ide_set_irq(s);
> break;
but if I look at some ATA-3 (draft) document I found
linked from wikipedia
(here:
http://www.t10.org/t13/project/d2008r7b-ATA-3.pdf
)
I find (pp 45,46) that the READY bit in fact should be set.
??
