I've got an old 7i43-400 EPP card that I'm using for testing on a conversion. I had no latency errors while I was using it with one of the stock servo-only firmware images (SV8.BIT). I needed to add a couple of stepgens on specific pins for testing, so I built FPGA firmware with a custom pinout.
that now, whenever I start linuxcnc, I get a realtime delay/latency error that I was not getting before. It happens right at launch every time.
Here are the modules enabled in my FPGA pin file. I've attached the whole thing as well.
Code:
(HM2DPLLTag, x"00", ClockLowTag, x"01", HM2DPLLBaseRateAddr&PadT, HM2DPLLNumRegs, x"00", HM2DPLLMPBitMask),
(WatchDogTag, x"00", ClockLowTag, x"01", WatchDogTimeAddr&PadT, WatchDogNumRegs, x"00", WatchDogMPBitMask),
(IOPortTag, x"00", ClockLowTag, x"02", PortAddr&PadT, IOPortNumRegs, x"00", IOPortMPBitMask),
(QcountTag, x"02", ClockLowTag, x"06", QcounterAddr&PadT, QCounterNumRegs, x"00", QCounterMPBitMask),
(PWMTag, x"00", ClockHighTag, x"03", PWMValAddr&PadT, PWMNumRegs, x"00", PWMMPBitMask),
(StepGenTag, x"02", ClockLowTag, x"02", StepGenRateAddr&PadT, StepGenNumRegs, x"00", StepGenMPBitMask),
(AddrXTag, x"00", ClockLowTag, x"01", TranslateRAMAddr&PadT, TranslateNumRegs, x"00", TranslateMPBitMask),
(SSerialTag, x"00", ClockLowTag, x"01", SSerialCommandAddr&PadT, SSerialNumRegs, x"10", SSerialMPBitMask),
Any obvious culprits I should look for? I don't have access to my config files at the moment (forgot to push them up to github last night), but I will be back at the machine later today.
