Table 2-10. Base Loader Page Settings
Setting Description
Category Selections in the drop-down box display panes of options. The options are:
•
Loader options – default booting options (this section)
• Boot kernel options – specification for a second-stage loader (see
on page 2-49 )
• ROM splitter options – specification for the no-boot mode (see
on page 2-51 )
If you do not use the boot kernel for ADSP-BF535 processors, the second Load
pane appears with all kernel option fields grayed out. The loader does not search
for the boot kernel if you boot from the on-chip ROM by setting the
-no2kernel
command-line switch as described on page 2-45 .
For ADSP-BF531/BF532/BF533 and ADSP-BF561 processors, which do not
have software boot kernels by default, you need to select the boot kernel to use
one.
Boot mode Specifies PROM, Flash, or SPI as a boot source.
Boot format Specifies Intel hex, ASCII, or binary formats.
Output width Specifies 8 or 16 bits.
If
BMODE = 01
or
001
and Flash/PROM is 16-bit wide, the 16-bit option must
be selected.
Start address
Specifies a PROM/Flash output start address in hex format for the application
code.
Verbose Generates status information as the loader processes the files.
Wait state Specifies the number of the wait states for external access (
0
–
15
).
The selection is active for ADSP-BF535 processors. For ADSP-BF531,
ADSP-BF532, and ADSP-BF533 processors, the field is grayed out.
Hold time Specifies the number of the hold-time cycles for PROM/Flash boot (
0
–
3
).
The selection is active for ADSP-BF535 processors. For ADSP-BF531,
