Experimental Physics and Industrial Control System
Thanks for your help!
I set the MRF_CONFIG_SITE like this:
EPICS_SUPPORTS_CRCSR = YES
BSP_SUPPORTS_CRCSR = YES
ADDRESS_MODE = USER
Now, I change it to be the same as you set:
EPICS_SUPPORTS_CRCSR = YES
BSP_SUPPORTS_CRCSR = YES
ADDRESS_MODE = SUPERVISOR
Then, I recompile the driver and run it.
The configure of st.cmd file is:
ErConfigureVME(0, 5, 0x280000, 0x62, 4)
EgConfigure(0, 3, 0x180000)
or
ErConfigureVME(0, 5, 0x0, 0x62, 4)
EgConfigure(0, 3, 0x10000)
The EgConfigure() no longer gives an error message, and the return value is 0.
But some new error messages appear:
...
EgConfigure(0, 3, 0x10000)
Evg status:0
#EgConfigTimeStamp(0, "NORMAL")
#ErConfigTimeStamp(0,"DBUS","","",0,0)
#var mySubDebug 1

Its the RTEMS EXCEPTION.
When I modify the st.cmd file as follows, the IOC can work well:
ErConfigureVME(0, 5, 0x280000, 0x62, 4)
#EgConfigure(0, 3, 0x180000)
I change the slot for EVG or use another crate, and the result do not change.
Should I do some special configuration for EVG?

> Hello all,

> I try to running the mrfEventSystem driver with EPICS 7 on RTEMS 5. After modifying part of the code, the driver can read the EVR(EVent Reciever) Card, and it works well. But when I run the driver and use the EVG(EVent Generator), I get this error: EgConfigure: Unable to read Event Generator Card 0 (slot 3) at VME/A24 address 0x1800000.
>
> In st.cmd file, the configuration for the EVG is EgConfigure(0, 3, 0x1800000). When I change the OS from RTEMS to vxWorks(on MVME6100 and MVME5500), the driver can read the EVG.

> I also compared the difference between the return value of EVG and EVR in the process of calling the function devReadProbe()(devReadProbe(sizeof(epicsUInt16), pEg, &Junk) and devReadProbe(sizeof(epicsUInt16), pEr, &Junk)).The source of the difference in the return value of devReadProbe() is that the return value of the RTEMS function _BSP_clear_hostbridge_errors() is different. The function as follows:

> unsigned long
> _BSP_clear_hostbridge_errors(int enableMCP, int quiet)
> {
> unsigned long rval;
>
> /* MCP is not connected */
> if ( enableMCP )

> rval = (clear_hose_errors(0, quiet) & PCI_ERR_BITS)>>8;
> rval |= clear_hose_errors(BSP_pci_hose1_bus_base, quiet) & PCI_ERR_BITS;
>
> /* Tsi148 doesn't propagate VME bus errors to PCI status reg. */
> if ( _BSP_clear_vmebridge_errors )
> rval |= _BSP_clear_vmebridge_errors(quiet)<<16;
>
> return rval;
> }
>
> (ret = _BSP_clear_hostbridge_errors(0,1); )
