Support can be enabled for different varieties of ROM

346 |

monitor. This support changes various eCos semantics such

347 |
|
|
as the encoding of diagnostic output, or the overriding of
|
348 |
|
|
hardware interrupt vectors.
|
349 |
|
|
Firstly there is \"Generic\" support which prevents the
|
350 |
|
|
HAL from overriding the hardware vectors that it does not
|
351 |
|
|
use, to instead allow an installed ROM monitor to handle
|
352 |
|
|
them. This is the most basic support which is likely to be
|
353 |
|
|
common to most implementations of ROM monitor.
|
354 |
|
|
\"GDB_stubs\" provides support when GDB stubs are included
|
355 |
|
|
in the ROM monitor or boot ROM."
