What kind of application are you writing? GUI, resource manager, data redirection?
What type of errors? Compiler errors? Linker errors? Run time errors? Maybe you should post the error messages.
Just a general comment. Day after day we see similar naive sounding questions here. They usually come in the form of; Something is wrong with my program, can you help me. Since the people who post these have managed to install QNX and write a ‘C’ or C++ program they are obviously not dumb. So why isn’t it obvious that anyone reading the post needs more information?
If you are unsure of what information would be useful, then a suggestion. Try building a very simple version of what you are trying to do. If that doesn’t work, then you have something simple to post here. If it does work, then add incrementally until your problem appears. Then you can post whatever it was that didn’t work.
BTW, this post is better than most in that at least we know you are using the omap3530 BSP and are having some kind of trouble with i2c and spi.
