 Status
 ======
-This BSP is not working.  It gets to the point where the 
+
-console_outbyte_polled() routine is called during printf
++ printk() works and is being called from bsp_start as prove.
-and it locks up checking for a status bit.  This is probably
+
-a simulator initialization issue related to the setup command.
++ There appears to be a compilation problem in _Thread_Handler_initialization
-As of 25 Nov 2000, email was sent to the gdb and newlib maintainers
+where _Thread_Ready_chain[1] is only 1 byte -- not 12 from
-asking for advice.
+_Thread_Ready_chain[0].   I am throwing this to the RTEMS list
+first before reporting it.
