Advanced Boot Techniques - Analog Devices ADSP-BF506F Hardware Reference Manual

For example in
Table 24-6 is placed at address 0x2000 0000, the boot kernel is instructed
to issue a
JUMP
The development tools must be instructed to link the above block to
address 0x2000 0000 and the application code to address 0x2000 0020.
An example shown in
illustrates how this is accomplished using the CCES or VisualDSP++ tools
suite.
