<div>Hi all<br>
<div><span class="406521009-18072006"><font face="Tahoma" size="2"><br>
We are porting
third party driver code from vxworks to Embedded
linux in MPC 8260 under a evaluation platform from Embedded Planet in linux kernel space.<br>
<br>
</font></span>
<div><span class="406521009-18072006"><font face="Tahoma" size="2">The first step we
carried out was reading the chip id and we were able to read the chip id
correctly.</font></span></div>
<div><span class="406521009-18072006"></span> </div>
<div><span class="406521009-18072006"><font face="Tahoma" size="2">For reading the
chip id we used the routine ChipReadMemory in the attached text and we were able
to retrive the chip id successfully.</font></span></div>
<div><span class="406521009-18072006"></span> </div>
<div><span class="406521009-18072006"><font face="Tahoma" size="2">Subsequently when
we write and read from Chip Specific Control Status registers ,it didn't
work.</font></span></div>
<div><span class="406521009-18072006"></span> </div>
<div><span class="406521009-18072006"><font face="Tahoma" size="2">I checked the
manual and the Chip Specific Control Status registers have RW
access.</font></span></div>
<div><span class="406521009-18072006"></span> </div>
<div><span class="406521009-18072006"><font face="Tahoma" size="2">Any inputs on how
to check if the write we made to virtual address succeeds?</font></span></div>
<div><span class="406521009-18072006"></span> </div>
<div><span class="406521009-18072006"><font face="Tahoma" size="2">Is there a way to
dump the linux virtual address and examine the write we
made ?<br>
<br>
