<DIV><FONT color=#000080>You can use mmap to access NVRAM from user space, but
you should config </FONT></DIV>
<DIV><FONT color=#000080>local bus first, like width, speed etc.</FONT></DIV>

<DIV><FONT face=Verdana size=2><STRONG>主题：</STRONG> How do I access nvRAM from
user space? </FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>
<DIV>Sorry for the dumb question, I just can figure out the right google search </DIV>
<DIV>to find what I'm trying to do. I'm running 2.6.27-rc4 on an mpc8347 with </DIV>
<DIV>a 32KiB nvSRAM (Cypress CY14B256L) on the local bus. We just want to be </DIV>
<DIV>able to access this memory from user space seperately from "main" memory. </DIV>
<DIV>We've got a process that needs to be able to remember info through power </DIV>
<DIV>cycles. Can anyone point me to an article or some code snippet that does </DIV>
<DIV>something like this so I can sink my teeth into it?</DIV>
<DIV></DIV>
