<physical_memory name= ....
       ....
 </physical_memory>

and 

  <physical_pool name= ....
      ....
   </physical_pool>

and not for the memsection entries for my user program

<memsection name = ....>

Thank you,

Hello I am trying to access a few register sets directly from an iguana example build on top of the OKL4 2.1 'empty' example. I have tried using hardware_back_memsection without success. I have also seen a previous post on this matter: <a style="font-weight: bold;" href="http://lists.okl4.org/pipermail/developer/2008-February/000607.html">http://lists.okl4.org/pipermail/developer/2008-February/000607.html</a> and tried to apply the same rules to my weaver.xml. Obtained the file below. That does not map the physical page(s) either. My problem is that I don't see the sections added in the page table, and the mapping_test function does not work. On top of that, whenever I
 change something in the code machines.py gets overwritten with a file that has nothing defined in the &lt;program_name section of the weaver file. I have to execute my build script twice, copying the weaver.xml back into build/images/ the second time to have the images build correctly. q0: Is hardware_back_memsection usefull in the OKL4 2.1? It always returns an error -1 when I try to use it in my example user application. I have tried the following code, not having the physical memory region premapped in the kernel (plat.cc) or in machies.py. struct etm_struct { &nbsp;&nbsp;&nbsp; memsection_ref_t ms; &nbsp;&nbsp;&nbsp; uintptr_t ms_base; }; .... &nbsp;&nbsp;&nbsp; struct etm_struct etm; &nbsp;&nbsp;&nbsp; int res; &nbsp;&nbsp;&nbsp; res = hardware_back_memsection(etm.ms, 0x10132000, L4_IOMemory); q1: Is the above mentioned email
 procedure still valid in OKL4 2.1? q2: what am I doing wrong in weaver.xml? q3: Do I need to modify machines.py or the SConstruct file from iguana/examples/empty folder to keep weaver.xml unchanged when I change my code? q4: Where do I need to modify so that the &lt;memsection name= ..../&gt; lines don't disappear each time I change a file. From what I can see adding more memory['xxx'] = [Region(....)] in machines.py only creates entries for &lt;physical_memory name= .... &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .... &nbsp;&lt;/physical_memory&gt; and &nbsp; &lt;physical_pool name= .... &nbsp;&nbsp;&nbsp;&nbsp; .... &nbsp; &lt;/physical_pool&gt; and not for the memsection entries for my user program &lt;memsection name = ....&gt; Thank you, Gabi Voiculescu -------------------------------------------------------------------------------------------------------------- weaver.xml file: &lt;?xml version="1.0"?&gt; &lt;!DOCTYPE image SYSTEM "weaver-1.1.dtd"&gt; &lt;image&gt; &nbsp; &lt;machine&gt; &nbsp;&nbsp;&nbsp; &lt;word_size size="0x20" /&gt; &nbsp;&nbsp;&nbsp; &lt;virtual_memory name="virtual"&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;region base="0x1000" size="0xdffff000" /&gt; &nbsp;&nbsp;&nbsp; &lt;/virtual_memory&gt; &nbsp;&nbsp;&nbsp; &lt;physical_memory name="physical"&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;region base="0x100000" size="0x7eff000" type="conventional" /&gt; &nbsp;&nbsp;&nbsp; &lt;/physical_memory&gt; &nbsp;&nbsp;&nbsp; &lt;physical_memory name="etm_mem"&gt; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;region base="0x10132000" size="0x1000" /&gt; &nbsp;&nbsp;&nbsp; &lt;/physical_memory&gt; &nbsp;&nbsp;&nbsp; &lt;physical_memory
