MMU interferes with PLB Master IP

We have a situation where a PLB bus Master IP works fine with standalone SW (no MMU) however when we run Linux

on the same system with MMU it seems to block the Master IP. Even after stopping Linux (w. XMD) and disabling the MMU the Master does not work. Somehow, the MMU continues to interfere. Has anyone got any ideas ?

 

Thanks,

Jacob

Hi,

 

sorry for the delay, can you explain more about what you mean by blocking the Master IP?

 

Thanks.

Little late in the game here, but did you ever find a solve for the problem? We're trying to use Petalinux, which requires MMU, but it doesn't seem to allow the master IP incorporated into our XPS project to access memory. It works fine bare-metal, with no Petalinux/MMU. 

 

Thanks!
