Blackfin Processor <strong>Loader</strong> Guide<br />
Table 2-10. Blackfin <strong>Loader</strong> Comm<strong>and</strong>-Line Switch Summary (Cont’d)<br />
Switch Description<br />
-compressWS # The -compressWS # switch specifies a compression window size in<br />
bytes. The number is a 2’s exponential value to be used by the compression<br />
engine. The valid values are [8, 15] bits, with the default of<br />
9 bits.<br />
� This<br />
switch is for PROM/flash boot modes only <strong>and</strong><br />
does not apply to ADSP-BF535, ADSP-BF538,<br />
ADSP-BF539, or ADSP-BF561/566 processors.<br />
-enc dll_filename The -enc dll_filename switch encrypts the data stream from the<br />
application input .dxe files with the encryption algorithms in the<br />
dynamic library file dll_filename. If the dll_filename parameter<br />
does not appear on the comm<strong>and</strong> line, the encryption algorithm<br />
from the default ADI’s file is used.<br />
-f hex, -f ASCII,<br />
-f binary, -f include<br />
The -f {hex|ASCII|binary|include} switch specifies the format<br />
of a boot-loadable file (Intel hex-32, ASCII, binary, include). If<br />
the -f switch does not appear on the comm<strong>and</strong> line, the default<br />
boot mode format is hex for flash/PROM <strong>and</strong> ASCII for SPI, SPI<br />
slave, UART, <strong>and</strong> TWI.<br />
-ghc # The -ghc # switch specifies a 4-bit value (global header cookie) for<br />
bits 31–28 of the global header (see Table 2-7 on page 2-44).<br />
� This<br />
switch can be applied to ADSP-BF561/BF566<br />
processors only.<br />
-h or -help The -h[elp] switch invokes the comm<strong>and</strong>-line help, outputs a list<br />
of comm<strong>and</strong>-line switches to st<strong>and</strong>ard output, <strong>and</strong> exits. By default,<br />
the -h switch alone provides help for the loader driver. To obtain a<br />
help screen for your target Blackfin processor, add the -proc switch<br />
to the comm<strong>and</strong> line. For example: type<br />
elfloader -proc ADSP-BF535 -h to obtain help for the<br />
ADSP-BF535 processor.<br />
-HoldTime # The -HoldTime # switch allows the loader utility to specify a number<br />
of hold time cycles for PROM/flash boot. The valid values (#)<br />
are from 0 through 3. The default value is 3.<br />
� This<br />
switch can be applied to ADSP-BF535 processors<br />
only.<br />
