Question about (and problem with) pflash data access

[Guenter Roeck]

Hi,

I have been playing with pflash recently. For the most part it works,
but I do have an odd problem when trying to instantiate pflash on sx1.

My data file looks as follows.

0000000 0001 0000 aaaa aaaa 5555 5555 0000 0000
0000020 0000 0000 0000 0000 0000 0000 0000 0000
*
0002000 0002 0000 aaaa aaaa 5555 5555 0000 0000
0002020 0000 0000 0000 0000 0000 0000 0000 0000
*
0004000 0003 0000 aaaa aaaa 5555 5555 0000 0000
0004020 0000 0000 0000 0000 0000 0000 0000 0000
...

In the sx1 machine, this becomes:

0000000 6001 0000 aaaa aaaa 5555 5555 0000 0000
0000020 0000 0000 0000 0000 0000 0000 0000 0000
*
0002000 6002 0000 aaaa aaaa 5555 5555 0000 0000
0002020 0000 0000 0000 0000 0000 0000 0000 0000
*
0004000 6003 0000 aaaa aaaa 5555 5555 0000 0000
0004020 0000 0000 0000 0000 0000 0000 0000 0000
*
...

pflash is instantiated with "-drive file=flash.32M.test,format=raw,if=pflash".

I don't have much success with pflash tracing - data accesses don't
show up there.

I did find a number of problems with the sx1 emulation, but I have no clue
what is going on with pflash. As far as I can see pflash works fine on
other machines. Can someone give me a hint what to look out for ?

Thanks,
Guenter
