StarterWare sample code.

Added by Edwin McKay over 4 years ago

I am trying to work with the StarterWare for the OMAPL138 special DBRIC-3 version. I thought I could import a couple of the projects and work with UART-echo example. However, I guess importing just the project does not work (or obviously I have missed some steps). The projects seem empty. So after reading the StartWare information again, I tried to just select the folder where the files are as my working directory. This appears to improve things, but not completely. I can compile the uartecho.c program, but the system_config reference in the uartEcho.cmd file can not be found. When I try to open the system_config project, a message appears indicating the .project file is missing.

My working folder is /media/sf_VMUbuntuBenchmike/OMAPL138_StarterWare_1_10_03_03/build/armv5/cgt_ccs/omapl138/MityDSPL138. I think the correct system_config project is up one directory in the omapl138 folder, or at least there are files there.

I am using CodeComposer 5.5.0 and have downloaded the "CL_MityDSPL138_StarterWare_06_20_12.zip" file. I am still using the Angstrom Linux and am developing mainly in Ubuntu 14.04.

Thanks for any guidance.

I went back to the most basic Hello World example and that compiled, linked and executed on the Mity board, so at least the Ubuntu, CCS, etc are working in some manner. So I proceeded to the Linux+DSP Hello world example. In the instructions the following is stated:
Copy dsplinkk.ko to the MityDSP-L138
See Starter Guide for details on copying files to the MityDSP-L138

I just wondered which folder these files are in. I did a "locate" and found 3 of them. Maybe it does not matter?

I got a little further, but I am always encounter the 0x80008050 error "#define DSP_EALREADYEXISTS (DSP_EBASE + 0x50l)". This is even after power cycling the system and running this program before anything else.

This board already has a DSP program running, but I want to replace it with the little test program.

Is there some way to "replace" or "over write" the tcDspApp::LoadApp command?

I stopped the initialization program from loading the normal DSP code that our sister company uses and then the Test Hello World application runs.
