Hi again,

Just to share that I could find the same behavior on a record on

mrfioc2. This one:

https://github.com/epics-modules/mrfioc2/blob/master/mrmShared/Db/databuftx.db#L2
https://github.com/epics-modules/mrfioc2/blob/master/mrmShared/src/devMrfBufTx.cpp#L171

If I try to create a similar softRecord it works as it should.

Cheers

Hi tech-talk,

I am facing a strange issue with a device support for one aao record (or

waveform), on that implementation when I change the value of the record

the pvmonitor is not updated but the camonitor it is.

For example:

$ pvput TD-TEST:EvtCodes-SP

[6,7,8,9,10,11,12,13,15,18,19,96,97,100,101,102,103,120,127,60,61,62,63,64]

$ pvmonitor TD-TEST:ScEvtCodes-SP

$ camonitor TD-TEST:ScEvtCodes-SP

I imagine I might be missing some piece of implementation of the device

support. Anyone has seen this before ? if someone has some simple

example of an aao device support implementation that could help also.

Thanks
