Hi, As most of you must be aware that a VME bus-error is a condition when there is no/unresponsive peripheral board preset at the address that is put on the bus by CPU for a read/write cycle. While using and reading about MVME5500 (with vxworks 6.9), I have realized that it is not possible to precisely catch a VME bus-error in software while doing a write operation on a peripheral board. This ,as I learnt, is due to the PCI bus based architecture of the board which uses write-posting. However, one can catch a VME bus-error during a read cycle as reading is done immediately from the peripheral board. Is this scenario same for all other CPU boards also (whether PowerPC or Intel based ) that have PCI bus based architecture. Regards, Stefen.
