Blackfin <strong>Loader</strong> Comm<strong>and</strong>-Line Switches<br />
<strong>Loader</strong>/Splitter for Blackfin Processors<br />
A summary of the Blackfin loader comm<strong>and</strong>-line switches appears in<br />
Table 2-10.<br />
Table 2-10. Blackfin <strong>Loader</strong> Comm<strong>and</strong>-Line Switch Summary<br />
Switch Description<br />
-b prom, -b flash,<br />
-b spi, -b spislave,<br />
-b UART, -b TWI,<br />
-b FIFO<br />
The -b {pro|flash|spi|spislave|UART|TWI|FIFO} switch<br />
specifies the boot mode <strong>and</strong> directs the loader utility to prepare a<br />
boot-loadable file for the specified boot mode. Valid boot modes<br />
include PROM, flash, SPI, SPI slave, UART, TWI, <strong>and</strong> FIFO.<br />
� SPI<br />
slave, UART, <strong>and</strong> TWI boot modes are for the<br />
ADSP-BF531/BF532/BF533/BF534,<br />
ADSP-BF536/BF537 <strong>and</strong> ADSP-BF538/BF539 processors.<br />
FIFO boot mode is for the ADSP-BF534/BF536 <strong>and</strong><br />
ADSP-BF537 processors, silicon revision 0.4 or<br />
newer only.<br />
If -b does not appear on the comm<strong>and</strong> line, the default is<br />
-b flash.<br />
-baudrate # The -baudrate # switch accepts a baud rate for SPI booting only.<br />
Valid baud rates <strong>and</strong> corresponding values (#) are:<br />
500K – 500 kHz, the default value<br />
1M – 1 MHz<br />
2M – 2 MHz<br />
Boot kernel loading supports an SPI baud rate up to 2 MHz.<br />
� This<br />
switch can be applied to ADSP-BF535 processors<br />
only.<br />
-compression The -compression switch directs the loader utility to compress the<br />
boot stream (see<br />
“ADSP-BF531/BF532/BF533/BF534/BF536/BF537 Processor<br />
Compression Support” on page 2-55). Either a default or user initialization<br />
.dxe file with decompression code must be provided for<br />
-compression.<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 />
