106 debug software such as Angel or eCos GDB stubs. Select 'rom'
107 when building a stand-alone application which will be put
108 into ROM. Using ROMRAM will allow the program to exist in
109 ROM, but be copied to RAM during startup."

188 Support can be enabled for different varieties of ROM monitor.
189 This support changes various eCos semantics such as the encoding
190 of diagnostic output, or the overriding of hardware interrupt
192 Firstly there is \"Generic\" support which prevents the HAL
193 from overriding the hardware vectors that it does not use, to
194 instead allow an installed ROM monitor to handle them. This is
195 the most basic support which is likely to be common to most
196 implementations of ROM monitor.
197 \"GDB_stubs\" provides support when GDB stubs are included in
198 the ROM monitor or boot ROM."
