<DIV><FONT face=Arial size=2>Help!</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I am using RTEMS and have written/ported my
own</FONT></DIV>
<DIV>BSP for a Huricane board with a RM5231 QED.</DIV>
<DIV> </DIV>
<DIV> I am trying to replace the </DIV>
<DIV>PMON's interrupt execetion vector</DIV>
<DIV>with my own. I assume it includes a</DIV>
<DIV>memcpy to 0x80000180 with the </DIV>
<DIV>new vector; SR(BEV) bit is set </DIV>
<DIV>accordingly; then an Icache invalidate.</DIV>
<DIV> </DIV>
<DIV>The memory write works fine</DIV>
<DIV>but the Invalidate hangs execution</DIV>
<DIV>within the debugger.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I have listed here the exact</FONT></DIV>
<DIV><FONT face=Arial size=2>instruction that is causing the Hurricane, my
board to hang</FONT></DIV>
<DIV><FONT face=Arial size=2>while steping through startup.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>cache 0x10, 0(0xffffffff80000180)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This instruction is supposed to Invalidate the
instruction cache if</FONT></DIV>
<DIV><FONT face=Arial size=2>the address 0xffffffff80000180 is in
cache.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Does anyone have any suggestions? Ideas? Could
the PMON be causing</FONT></DIV>
<DIV><FONT face=Arial size=2>this problem?</FONT></DIV>
<DIV> </DIV>
<DIV>Thanks</DIV>
