Dear Sir:
 
     I have developed the TD4V card's EPICS driver successfully under the help of Tobiyama, TD4V card is a programmable delay module used in Timing system ( KEKB guys maybe familar with this card). The developing system was based on mv162+Redhat6.2(with EPICS).
     The card initing code of device support is like this:
 
if(sysBusToLocalAdrs(VME_AM_EXT_SUP_DATA,(char *)Base_IO,(char **)&p)==ERROR)
{
       logMsg("VmeTd4v: cannot find extended address space\n");
       return(ERROR);
}                                        /* The memory of 162 is correct*/
for(cardNum=0;cardNum<td4v_num_links;cardNum++)
{
    if(vxMemProbe((char *)&(p->PreSet),READ,2,&probeVal[0])<OK)
    {
        logMsg("No TD$V with cardNum=%d\n probe=%x\n",cardNum,p);
        cards[cardNum].card=NULL;
    }
    else
    {
        logMsg("Found TD4V with cardNum=%d\n address=%x\n",cardNum,p);
        cards[cardNum].card=p;
    }
...
 
Now I want to change the mv162 board to mv2302. using the same initing code. and set the proper Base_IO address under the instruction of .../target/config/mv2302/target.nr  This time it doesn't work at all.
What's wrong about the memory map of 2302 ?
