Blackfin Processor Loader/Splitter
Using Second-Stage Loader
If you to use a second-stage loader, select Boot kernel options in the Cat-
egory drop-down menu. The page shows how to configure the loader for
boot loading and to output file generation using the boot kernel.
Figure 2-15 shows an example boot kernel Load pane for a Blackfin
processor.
To create a loader file which includes a second-stage loader:
1. Use the Loader options pane to set up base booting options (see
“Using Base Loader” on page 2-47 ).
2. Select Boot kernel options from the Category drop-down box to
open the second Load pane with the second-stage loader settings,
shown in Figure 2-15 .
Baud rate Specifies a baud rate for SPI booting (
500
kHz,
1
MHz, and
2
MHz).
The selection is active for ADSP-BF535 processors. For ADSP-BF531,
ADSP-BF532, and ADSP-BF533 processors, the field is grayed out.
Initialization
file Directs the loader to include the initialization file (Init code). The Initialization
file selection is active for ADSP-BF531/BF532/BF533, and ADSP-BF561 pro-
cessors. For ADSP-BF535 processors, the field is grayed out.
Kernel file Specifies the boot kernel file. Can be used to override the default boot kernel if
there is one by default, as on ADSP-BF535 processors.
Output file Names the loader’s output file.
Additional
options Specifies additional loader switches. You can specify additional input files for a
multiinput system.
Note: The loader processes the input files in order the files appear on the com-
mand line, starting with the one from the project.
