Kurt Goetze and I discovered a design problem with the OMS MAXv motion control board . The problem is that the MAXv board fails to initialize correctly after reset or power-cycling approx. 15% of the time. OMS explains, The FPGA that controlled VME communications of the MAXv controller was
OMS has fixed the problem. MAXv boards with FPGA code version A6 and above are fixed. Users with FPGA code version A5 and below should obtain a RMA from OMS and request Engineering Change Order (ECO) #1432. There is no charge for the upgrade. You can determine the FPGA code version of your MAXv boards by issuing the following command at the IOC shell (note the "FPGA:B1:A6" section); epics> dbior "drvMAXv" Until all the MAXv boards in a give IOC are "fixed", I recommend that you use the above 'dbior "drvMAXv"' command after every reset and power-cycle to determine if all the MAXv boards have initialized correctly. The MAXv boards that did not initialize correctly will have the "... not found." message. Example below; epics> dbior "drvMAXv"
