Re: How to compile the sysVmeMapShow() function to the MVME5500 BSP?

[éè <yanfen@sinap.ac.cn>]

Dear Andrew,

I'm from SSRF. After I use sysVmeMapShow() function to the MVME5500 BSP, it display as follow:

      -> sysVmeMapShow                                                                
                                                                                
       VMEbus access from CPU:                                                         
        CPU:  0xE7F00000 - 0xE7F3FFFF  =>  A32: 0xE7F00000 - 0xE7F3FFFF               
        0xEFF00000 - 0xF0EFFFFF  =>  A24:   0x000000 -   0xFFFFFF               
        0xF0F00000 - 0xF0F0FFFF  =>  A16:     0x0000 -     0xFFFF               
                                                                                
        CPU access from VMEbus:                                                         
        A32:             -             =>                  -                          
        A24:    0x000000 -   0xFFFFFFFF  =>       0x0F0F0000 - 0x0F0EFFFF             
        value = 0 = 0x0  

Do you think the display is OKïThe A32 address is available? Would you mind give me some suggestion about the blank of A32 address in "CPU access from VMEbus"?

Thank you very much!

Best wishes,

Yan Fen

Hi Robert,

Sorry for the delay, I was hoping that someone from SNS would respond since 
you're talking about their website.

The sysVmeMapShow() function there was mine, along with a number of other 
changes I make to all the BSPs I maintain here at APS.  I don't think SNS 
should be distributing their complete mv2100 BSP source code on the Internet 
though, their license agreement with Wind River is unlikely to permit them to 
do that.  I would be very happy if Wind River were to make their BSPs Open 
Source, but to the best of my knowledge they are still proprietary source code 
protected by their license agreements.

The MVME5500 uses a Universe-2 chip to interface to the VMEbus, so the 
sysVmeMapShow() function from the mv2100 or mv2700 BSPs should be very similar 
to what you need for the mv5500.  There are instructions on how to add this to 
the mv2700 at http://www.aps.anl.gov/epics/tech-talk/2006/msg00681.php and if 
you understand what the BSP is doing it should be fairly easy to adapt the 
code for the mv5500.

Hope this helps,

- Andrew
