Dear Tomek,
I applied your suggestion, with some variants, because on this test I am
running the 2.0.37 kernel with RTL1.3 which means the ioremap should be
changed with vremap which returns a virtual address that is used to access
the real physical address.
So with the following modification
sptr = (STRUCTTEST *) vremap(BASE_ADDRESS, 8);
it does work on the AMD5x86 and on the 386.
The question that comes out now is:
Why the code I sent was working perfectly on the Pentium PC104 and on the
developping system (PentiumMMX) even without the vremap and it was not on
the AMD and 386 ? Do you have any ideas ?
Thank you
Ciao
Giovanni
