Blackfin Processor Loader Guide
2-44 Vi+ Loader Manual
for 16-Bit Processors
-kp #
Specifies a hex PROM/Flash output start address for kernel code. A
valid value is between [
0x0
,
0xFFFFFFFF
]. The specified value will
not be used if no kernel or/and initialization code is included in the
loader file.
-k Width #
Specifies the width of the boot kernel output file when there are two
output files: one for boot kernel and one for user application code.
Valid values are:
•
8
or
16
for PROM or Flash boot kernel
•
8
for SPI boot kernel
If this switch is absent from the command line, the default file width
is:
•
the
-width
parameter when booting from PROM/Flash
•
8
when booting from SPI.
This switch should be used in conjunction with the
-o2
switch.
-l userkernel
Specifies the user’s boot kernel. The loader utilizes the user-specified
kernel and ignores the default boot kernel if there is one.
Note: Currently, only ADSP-BF535 processors have default kernels.
-M
Generates make dependencies only, no output file will be generated.
-maskaddr #
Masks all EPROM address bits above or equal to
#
.
For example,
-maskaddr 29
(default) masks all the bits above and
including
A29
(ANDed by
0x1FFF FFFF
). For example,
0x2000 0000
becomes
0x0000 0000
. The valid
#
s are integers
0
through
32
, but based on your specific input file, the value can be
within a subset of
[0,32]
.
This switch requires
-romsplitter
and affects the ROM section
address only.
-MaxBlockSize #
Specifies the maximum block byte count, which must be a multiply
of 16.
-MM
Generates make dependencies while producing the output files.
-Mo filename
Writes make dependencies to the named file.
The
-Mo
option is for use with either the
-M
or -
MM
option. If
-Mo
is
not present, the default is
a <stdout>
display.
