_cplb_ctrl is used as part

of the instruction/parity

workaround but may not be

initialized before use

The _cplb_ctrl variable is checked during the startup code

sequence to see if instruction caching is enabled; if it is, instruction

parity is disabled to avoid anomaly 16000005 ("Using L1 Instruction

Cache with Parity Enabled is Unreliable").

If runtime initialization support is enabled (i.e. the "- mem" switch is

used or "Runtime initialization" is selected in the linker project

options), _cplb_ctrl will be checked before it is initialized by the

runtime initialization sequence, and will contain a random value.

This can mean that parity and instruction caching get enabled

together and the anomaly will be hit.

To avoid this issue, do one of the following:

- do not use runtime initialization.

- disable instruction caching..

- disable parity support by defining parity_ctrl to zero.

included in libssl

The ADSP-BF609 Watch Dog Timer (WDT) service sources were

not built into the System Services library

Blackfin\lib\bf609_rev_any\libssl.dlb

Blackfin\lib\bf609_rev_none\libssl.dlb

To use the WDT you will need to include its source file into your

project.

Blackfin\lib\src\services\source\wd\adi_wd.c

The header file to include to include in your project is

#include <services\wd\adi_wd.h>
