|
When targetting the EDK7708 board it is possible to build
|
86 |
|
|
the system for either RAM bootstrap or ROM bootstrap.
|
87 |
|
|
RAM bootstrap generally requires that the board
|
88 |
|
|
is equipped with ROMs containing a suitable ROM monitor or
|
89 |
|
|
equivalent software that allows GDB to download the eCos
|
90 |
|
|
application on to the board. The ROM bootstrap typically
|
91 |
|
|
requires that the eCos application be blown into EPROMs or
|
92 |
|
|
equivalent technology. ROMRAM bootstrap is similar to ROM
|
93 |
|
|
bootstrap, but everything is copied to RAM before execution
|
94 |
|
|
starts thus improving performace, but at the cost of an
|
95 |
|
|
increased RAM footprint."
