Hi Mark,
Thanks for your tips. Sorry for the long email...
> When I look up those parameters in your template file I see that those are mbbo/mbbi records. You said that other parameters are called correctly for both addr=0 and addr=1. Can you see if the mbbo/mbbi records all fail to be called with addr=1 and all other record types are called OK with addr=1?
So, I commented most of my st.cmd file and it look like this now:
< envPaths
# Override default TOP variable
epicsEnvSet("TOP","../..")
epicsEnvSet("EPICS_DB_INCLUDE_PATH", "$(ADCORE)/db")
epicsEnvSet("BPM_TYPE","FMC250M_4CH")

#set_savefile_name("auto_settings.req", "auto_settings_${P}${R}.sav")
Only the BPMAcq.template and the BPMTrigger.template files are loaded. Plus, I added right at the end of my readUInt32Digital (), readInt32 () and readFloat64 () functions the following snippet (example showing for int32):
asynPrint(pasynUserSelf, ASYN_TRACE_ERROR,
"%s:%s: readInt32 parameter addr = %d, value = %u, functionId = %d, paramName = %s\n",
driverName, functionName, addr, *value, function, paramName);
So, it should print the print everytime a read is executed.

So, loading the BPMAcq.template (which has longout/longin, mbbo/mbbi, ao/ai records) with addr = 0 and addr = 1 showed that only read functions for addr = 0. The longin records were also called (last 4 readUInt32Read messages) (BPMTrigger.template has 2 records that are longin), but I guess that's because PINI = "yes" for those *in records. Does that make sense?
> I also notice that some of your mbbo records use asynInt32, e.g. BPM_MODE, and some use asynUInt32Digital, e.g. ACQ_TRIGGER. Does one of the interfaces fail and one work for mbbo records? Why are you using different interfaces for different records?
It seems that they all fail for addr = 1 (different from what I had previously said), except the case for longin records (but I think this is another this, because for longin values are not read on devce init, right?). I was using differente interfaces because BPM_MODE is just an IOC parameter to select between two operation modes and ACQ_TRIGGER is a hardware value that are mapped to a register inside an FPGA. I guess I could have used the same interface for both, but I though it made sense to distinguish those two.
> That code is called for every mbbo record unless init_common returns an error. If init_common returns an error it always prints an error message. Did you check carefully that there are no error messages right after iocInit?
> If you still think your driver is not being called for addr=1 with those parameters you could add a debugging printf just before the above call that prints pPvt->portName, pPvt->addr, and pPvt->userParam. That will show you if it is calling the port for addr=1 and that parameter string.
So, I added the following to devAsynUInt32Digital.c:
printf("initLo: portName = %s, addr = %d, userParam = %s\n",
pPvt->portName, pPvt->addr, pPvt->userParam);
/* Read the current value from the device */
status = pasynUInt32DigitalSyncIO->read(pPvt->pasynUserSync,
&value, pPvt->mask,pPvt->pasynUser->timeout);
...
printf("initMbbo: portName = %s, addr = %d, userParam = %s\n",
pPvt->portName, pPvt->addr, pPvt->userParam);
/* Read the current value from the device */
status = pasynUInt32DigitalSyncIO->read(pPvt->pasynUserSync,
&value, pPvt->mask, pPvt->pasynUser->timeout);
