Re: [c3x] Run time library | Code-Composer

Keith, Thanks for the response. With a little nosing around in the various documentation, I found that the 'b' is a typical indicator of a library built for the "big" memory model. So I have tried rebuilding the library for this mode. I am not very familiar with the TI DSP libraries so I am not sure which sources to use, but I tried rts.src and it seems to have done the job. But this was for a very, very simple test program that uses no IO or other features that might be in the library (it just blinks an LED on the board). So I will give it a better test later when I recompile our boot monitor program. The other source files include prts30.src and mathasm.src. I assume that these are compiled separately for separate libraries, correct? Or are they intended to be included in the same library with rts.src?
