BSL API Modules

1.2 BSL API Modules

For each on-board device, one header file and one source file will be gener- ated with the following names: bsl_device.h and bsl_device.c.

Also, a library will be built for a given board:

i.e: bsl6711dsk.lib

Note : The soource files.c are archived into a single source file bsl.src.

Table 1–1 provides a current list of BSL API Modules.

Interdependencies

Although each API module is unique, there exists some interdependency be- tween the CSL (Chip Support Library) and BSL modules. For example, the AD535 module depends on the MCBSP module because MCBSP0 is dedi- cated to serial communication.

1.2.1BSL API Module Support

Not all API modules are supported on all boards. For example, the AIC10 mod- ule is not supported on the C6711 DSK because the board does not have an AIC10 codec. When an API module is not supported, all of its header file infor- mation is conditionally compiled out, meaning the declarations will not exist. Because of this, calling an AIC10 API function on a board that does not support AIC10 results in a compiler and/or linker error.

Note: AIC10 codec is implemented on C5510evm.
