I've been trying to use my RME HDSP PCI + Digiface, and do some experimental DSP with Nallatech BenOne with an FPGA on it, but in Fedora core 6, (because the DSP builder can only provide me with drivers for that) but when I try to use both cards at the same time the system doesn't see the HDSP, i can't load the firmware with the hdsploader app. nor using the mixer or anything. an extract of results of the "lspci -vv" command are: 06:01.0 Co-processor: Xilinx Corporation Unknown device 4029 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping+ SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 Interrupt: pin A routed to IRQ 74 Region 0: Memory at 70014000 (32-bit, non-prefetchable) [size=16K] 06:03.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP (rev 35) Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 Interrupt: pin A routed to IRQ 185 Region 0: Memory at 70000000 (32-bit, non-prefetchable) [size=64K] Anyone ever had a problem similar to this one? . Thanks in advance for any help. -- Moisés AAC
