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.
Here is the hardware I am using: EVG: VME-EVG-230. EVR: VME-EVG-230-RF. Single board computer: MVME6100 and MVME5500. The software: mrfEventSystem Driver Version: MRF Series 200 Event System Software Release V2-4. EPICS Version: 7.0.6.1 RTEMS Version: 5
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 (ret = _BSP_clear_hostbridge_errors(0,1); ) The ret is return value of the bspExtMemProbe().
Do you have any suggestions?
Thank you! chengsn IHEP
