Switch S8 is disabled by default. To enable it, you must change
the state of the parameter baseboard.sp810_sysctrl.use_s8 to true before
you start the model. See Emulation Baseboard parameters.
If you have a Boot Monitor flash image loaded, switch S8 enables
you to remap boot memory.
On reset, the EB hardware starts to execute code at 0x0,
which is typically volatile DRAM. You can put the contents of non-volatile
RAM at this location by setting the S8 switch in the EB FVP CLCD
as shown in Table 7.5.
The settings take effect on model reset.
Table 7.5. EB System Model switch S8 settings
| Switch S8[4:1] | Memory Range | Description |
|---|
| 0000 | 0x40000000-0x4FEFFFFF | NOR flash remapped to 0x0 |
| 0001 | 0x44000000-0x47FFFFFF | NOR flash remapped to 0x0 |
| 0010 | 0x48000000-0x4BFFFFFF | SRAM remapped to 0x0 |
Note
Attempting to change switch S8 settings after the model has
started, for example by using the CLCD DIP switches, might lead
to unpredictable behavior.
