Hello Gents,
I am trying to reach PCISTATSET from our PCI host. It sounds like I should map 0x02C00000 to one of the BAR using the translation registers and these registers are available in the backend registers also. It sounds a bit like the chicken and the egg. Does it means it is mandatory to have a DSP software modifying these registers and then we can do PCI boot or is there anything I can do. I was hoping everything was achievable from the host side. The default translation is as the following:
BAR0 : 0x00080000 (8MB)
BAR1 : 0x00180000 (4MB)
BAR2 : 0x00280000 (8MB)
BAR3 : 0x08000000 (8MB)
BAR4 : 0x0A000000 (8MB)
BAR5 : 0x0E000000 (8MB)
So if my understanding is correct there are no way to typically send a DSPINT via PCISTATSET unless the DSP as previously mapped the 0x02C00000 to maybe BAR3.
Any ideas/comments are welcome of course,
Thanks!
Arnaud
