using SDK in 56F807

Started by aaronedsinger July 19, 2003
Hi, I have a few newbie questions. I am using the SDK on the 56F807
evaluation module. If I create an Flash_Application from SDK
stationary, the default project works fine. However:

- If I look at the code size, the dspfunc.lib, bsp.lib, and msl c
56800.lib are larger than the availabe on chip flash/ram. It seems
that I shouldn't be able to use the SDK in flash?

-If I add a printf statement to the default main.c, the debugger
stops at the printf when run. If I step over the statement, the
debugger jumps to configUnhandledInterruptISR. Why don't I my printf
in the console window?

Thanks so much for any help.

>>You can use SDK projects to run from Flash. The size showed in the CodeWarrior
window is the total size of these libraries. However, the linker removes all
unused code (deadstripping) from the SDK libraries.

-If I add a printf statement to the default main.c, the debugger
stops at the printf when run. If I step over the statement, the
debugger jumps to configUnhandledInterruptISR. Why don't I my printf

>> printf consumes a large block of RAM, so when running from internal memory
you will probably need to use another method of displaying, like SCI.

Thanks so much for any help.
