BSP Developer’s Guide, 6.0

compatibility, these drivers are available in target/src/drv/serial. However, no new

development should be done with these drivers. If serious problems are

encountered with the old serial driver, it is recommended that you convert the BSP

to use an SIO driver.

3.3 Finalizing Your BSP

This section summarizes the remaining tasks essential to completing your BSP

port. Included is a discussion of cleanup, timers, networking, and other issues.

3.3.1 Cleanup

During BSP development, a number of files may be changed, and specific

debugging routines are developed. These changes should be cleaned up before the

BSP is finalized.

After the BSP is working with a minimum set of drivers, the private copies of

usrConfig.c and bootInit.c should be removed from the BSP directory so that the

BSP uses the generic versions of these files (located in the target/config/all

directory). To reinstall the generic versions, remove the following lines from your

BSP Makefile:

BOOTINIT = bootInit.c

USRCONFIG = usrConfig.c

And then perform a make clean.

Previously, you may have masked out unwanted configuration code with

#if FALSE/#endif pairs. Now the unwanted code must be removed in a more

standard way. That is, you must undefine the appropriate macros in config.h.

Keep in mind the macro dependencies listed in the usrDepend.c file (located in

target/src/config/).

The LED routines used for debugging are typically short and are likely to be useful

for applications after BSP development is complete. For these reasons, they should

not be removed. If the routines have not been rewritten in C, you may want to

rewrite them now in order to ease the future support burden.

After the port is finished, the kprintf( ) routine should not be used. It may be

appropriate to leave the routine in the source file for future support requirements.
