Hi,
I am trying to test an asyn based driver for the digitel multi-pump
controller(MPC). The MPC is connected to MVME2100 through a bitbus
controller VMOD-2 and a RS232 BUG(bitbus universal gateway). The device
support is part of sysApps package. The software module I also loaded is
asynSerialBUG, which is asyn support for the BUG.
IOC(on vxWorks 5.5, base 3.14.10) works fine with asyn traceflow off.
But it crashes when asyn traceflow turned on with the following info:
2009/07/30 16:53:14.088 PortA -1 exception 3 occurred calling
exceptionUser
2009/07/30 16:53:14.088 PortA -1 exception 3 occurred calling

The console shows the following info after a VME crate reset.
Exception at interrupt level:
program
Exception current instruction address: 0x0000b030
Machine Status Register: 0x00089030
Condition Register: 0x40000042
Regs at 0x235760
Link Register: 0x00104a3c
Exception at interrupt level:

Has anybody experienced similar problem and how to fix it?
Thanks,
Shifu
