    99The following is not 100% correct since it does not work.   :)

    1613Status
    1714======
    18 This BSP is not working.  It gets to the point where the
    19 console_outbyte_polled() routine is called during printf
    20 and it locks up checking for a status bit.  This is probably
    21 a simulator initialization issue related to the setup command.
    22 As of 25 Nov 2000, email was sent to the gdb and newlib maintainers
    23 asking for advice.
     15
     16+ printk() works and is being called from bsp_start as prove.
     17
     18+ There appears to be a compilation problem in _Thread_Handler_initialization
     19where _Thread_Ready_chain[1] is only 1 byte -- not 12 from
     20_Thread_Ready_chain[0].   I am throwing this to the RTEMS list
     21first before reporting it.
     22
     23Made it to bsp_start
     24mips-core: 4 byte write to unaligned address 0x8803bb01 at 0x8800d83c
     25
     26Program received signal SIGBUS, Bus error.
     270x8800d83c in _Chain_Initialize_empty (the_chain=0x8803bb01)
     28    at ../../../../../jmr3904/lib/include/rtems/score/chain.inl:222
     29222       the_chain->first          = _Chain_Tail( the_chain );
