Folks,
Tonia Batten is having a very strange problem that I cannot understand, perhaps someone on tech-talk has an idea.
She is using the Newport XPS motor driver. It works fine when it is run on an Intel machine. However, when it is run on an armv5teb she is seeing a behavior I cannot understand. This happens both with the older model 2 XPS driver (C code), as well as the newer model 3 driver (C++).
The asyn device support defines the following message structure:
typedef struct {
motorCommand command;
interfaceType interface;
int ivalue;
double dvalue;
} motorAsynMessage;
In the code that is called from the motor record it does the following:
/* Make a copy of asynUser. This is needed because we can have multiple
* requests queued. It will be freed in the callback */
pasynUser = pasynManager->duplicateAsynUser(pasynUser, asynCallback, 0);
pmsg = pasynManager->memMalloc(sizeof *pmsg);
pmsg->ivalue=0;
pmsg->dvalue=0.;
pmsg->interface = float64Type;
pasynUser->userData = pmsg;
switch (command) {
...
case SET_VELOCITY:
pmsg->command = motorVelocity;
pmsg->dvalue = *param;
break;
...
/* Queue asyn request, so we get a callback when driver is ready */
pasynUser->reason = pPvt->driverReasons[pmsg->command];
status = pasynManager->queueRequest(pasynUser, 0, 0);
So in the case of the SET_VELOCITY it copies the desired velocity to pmsg->dvalue. It calls pasynManager->queueRequest to call back device support when the driver is ready.
This is the start of the code in the device support callback function:
static void asynCallback(asynUser *pasynUser)
{
motorAsynPvt *pPvt = (motorAsynPvt *)pasynUser->userPvt;
motorRecord *pmr = pPvt->pmr;
motorAsynMessage *pmsg = pasynUser->userData;
int status;
int commandIsMove = 0;
pasynUser->reason = pPvt->driverReasons[pmsg->command];
Tonia has added some debugging to the device support code. When the velocity is being set, for example the code called by the motor record prints the following:
2014/05/02 10:10:56.266 devMotorAsyn::send_msg: SMTR1608-9-B20-05:brag command=7, pact=1, value=45000.000000
devAsynMotor::build_trans, calling queueRequest, pmsg=0x60b3cc, command=7, interface=1, dvalue=45000.000046
This is fine, the value 45000. has been copied to pmsg->dvalue
However, when pasynManager does the callback to device support from the queueRequest she sees the following:
devAsynMotor::asynCallback, entry, pmsg=0x60b3cc, command=7, interface=1, dvalue=0.000000
2014/05/02 10:10:56.308 devMotorAsyn::asynCallback: SMTR1608-9-B20-05:brag command=7, ivalue=0, dvalue=0.000000, pasynUser->reason=7
2014/05/02 10:10:56.310 asynMotorController:writeFloat64:: axis=0, function=7, value=0.000000
Note that pmsg has the same address (=0x60b3cc,), so it is getting a pointer to the same address as before the queueRequest.
However, pmsg->dvalue is now 0, rather than 45000.
Any idea how this could happen?
Thanks,
Mark

Hi Mark,
I am experiencing the same problem using the model 3 XPS driver. I have included details from my testing below. I can’t see anything in asyn-4-22/asyn/asynDriver/asynManager.c queueRequest function that would cause this. Any insight you can provide is appreciated.
Regards, Tonia
Here is my st.cmd file.
