Hi John,
Inside your dbLoadRecords second argument, try removing the single quote characters from around the word ‘SERIALPORT’.

The ioc runs fine under petalinux on zcu106. The simulator uses /dev/ttyUSB0 to talk to a labview application that feeds the data. The example is based upon an arduino example I found on the web. Very simple.
