ADSP-BF531/BF532/BF533 and ADSP-BF561 Multiple
.DXE Booting
This section describes how to boot more than one
ADSP-BF531/BF532/BF533 and ADSP-BF561 processor. The informa-
tion presented in this section applies to all of the named processors. For
additional information on the ADSP-BF561 processor, refer to
"ADSP-BF561 Multiple .DXE Booting" on page
The ADSP-BF531/BF532/BF533 and ADSP-BF561 loader file structure
and the silicon revision of 0.1 and higher allow to boot multiple
into a single processor from external memory. Each executable file is pre-
ceded by a 4-byte count header, which is the number of bytes within the
executable, including headers. This information can be used to boot a spe-
cific into the processor. The 4-byte

Booting multiple executables can be accomplished by one of the following
methods.
1. Use the second-stage loader switch,
allows to use your own second-stage loader or kernel.
After the second-stage loader gets booted into internal memory via
the on-chip boot ROM, it has full control over the boot process.
Now the second-stage loader can use the
