Hi Holyeong,

I don't think that is a good assumption, I think it is much more likely that the jumpers are in the wrong position or that you have your startup commands incorrect than that you have a hardware problem.

I helped you with this identical problem in November 2022, showing you which jumpers to set.  You reported that when you followed my directions it worked fine.  This is the follow-up tech-talk message I posted which contains our offline e-mail thread.

Subject: About MAXv controller PV recognize problem

 

Hi,

Before I ask a question, I would like to thank the epics tech talk for helping me. I’m a beginner in epics and RTOS, but I was able to come to this step with a lot of help. Really appreciate it.

 

I try to boot MVME6100 with epics st.cmd, MAXv controller. But it shows me a error like this :

 

Starting iocInit

############################################################################

## EPICS R3.15.6

## EPICS Base built Oct  7 2022

############################################################################

Illegal field value PV: oms:m1 motor_init_record_com(): card does not exist!

 

Illegal field value PV: oms:m2 motor_init_record_com(): card does not exist!

 

Illegal field value PV: oms:m3 motor_init_record_com(): card does not exist!

 

Illegal field value PV: oms:m4 motor_init_record_com(): card does not exist!

 

Illegal field value PV: oms:m5 motor_init_record_com(): card does not exist!

 

Illegal field value PV: oms:m6 motor_init_record_com(): card does not exist!

 

Illegal field value PV: oms:m7 motor_init_record_com(): card does not exist!

 

Illegal field value PV: oms:m8 motor_init_record_com(): card does not exist!

 

 

But “dbl”, this command shows me a pv list

-> dbl

oms:m1

oms:m2

oms:m3

oms:m4

oms:m5

oms:m6

oms:m7

oms:m8
value = 0 = 0x0

 

I can see EPICS IOC booting well, but MAXv card does not recognize PVs.

If it is assumed that the software or the jumper setting of the MAXv contoller is correct, is it okay to judge that the MAXv controller can’t communication VME Bus?

Before sending the MAXv controller repair, I would like to ask for your opinion as an expert.

 

Thank you and Best Regards,

Holyeong Baeg.
