I'm using a Digital I/O driver to handle a Philips board since 1 year; this driver has been developed with the contribution of an external resource. On VME we have other boards working with other drivers; no problem at all untill I install a SCSI disk on the KAV30 port. What appens is the follow: as soon I have to handle an interrupt from the Digital I/O board I loose the disk (I get time-out at any operation). I have been investigated on interrupt vector as the only area where I can see relation between VME bus and SCSI device. I tried to change vector but I didn't get positive result. Also I don't see errors in the ISR. If I set the board and the driver to work in polling mode instead of interrupt mode I avoid the problem. I'm looking for an help to focus my next tests, thanks in advance for support. Marino Formia

123.1 | What's your configuration ? | SOLVIT::YAHUDI::SYSTEM | Thu May 05 1994 23:54 | 24 | |
Hi Marino, What type of SCSI disk do you have connected to the KAV30 ? Is it a DEC qualified disk for use with VAXELN - see the VAXELN release notes for a valid list. Also is your system using the standard SCSI drivers, and not a customised version ? Also can you provide a detailed description of your VMEBus configuration. One thing to try is to use a VME tracer (eg VMETRO) to see what is happening on the VMEBus when you loose the disk drive, ie confirm it is as it should be wrt to IRQ being generated/received. If this is a major problem then we can try and simulate this problem in Munich. Hope this helps. Regards John Cushnie@PCS DEC-PCS, Munich. | |||||
123.2 | please note revision of KAV30... | EICMFG::KAV30_SUPP | Fri May 06 1994 10:01 | 8 | |
Hi, the problem sounds somewhat familiar... could you please post the version and revision of your KAV30 ? e.g. KAV30-xx, Rev Ax or Bx or C01 ? Thanks! Thomas | |||||
