 Simulator Invocation
 ====================
-The following is not 100% correct since it does not work.   :)
+The following is how the simulator is invoked.
 
-target sim --board=jmr3904pal --memory-region 0x8800000,0x100000
+target sim --board=jmr3904
+
+GDB must be configured with a target like "tx39-rtems".  Otherwise,
+the simulator will not be built for the correct instruction
+and peripheral set.
 
 Status

-+ printk() works and is being called from bsp_start as prove.
-
-+ There appears to be a compilation problem in _Thread_Handler_initialization
-where _Thread_Ready_chain[1] is only 1 byte -- not 12 from
-_Thread_Ready_chain[0].   I am throwing this to the RTEMS list
-first before reporting it.

-Made it to bsp_start
-mips-core: 4 byte write to unaligned address 0x8803bb01 at 0x8800d83c
++ hello.exe locks up while running the global destructors.  This almost
+  has to be a linkcmds issue.
 
-Program received signal SIGBUS, Bus error.
