1To run RTEMS from scratch (without any other bootcode) on the beagles,
2you can comfortably load the executables over JTAG using gdb. This is
3necessarily target-specific however.

7  - For access to JTAG using openocd, see simscripts/bbxm.cfg.
8  - openocd then offers access to gdb using simscripts/gdbinit.bbxm.
9  - start openocd using bbxm.cfg
10  - copy your .exe to a new dir and that gdbinit file as .gdbinit in the same dir
11  - go there and start gdb:
12    $ arm-rtems4.11-gdb hello.exe
13  - gdb will invoke the BBXM hardware initialization in the bbxm.cfg
14    and load the ELF over JTAG. type 'c' (for continue) to run it.
15  - breakpoints, C statement and single-instruction stepping work.

19This has been tested with openocd and works but not in as much detail as for
20the BBXM yet (i.e. loading an executable from scratch).
