printf() is a standard C library function. If you want more information about it, study man 3 printf or use any generic Internet search engine to find online documentation. printf() is not a debug tool, just a convenient output service in an environment that supports it, and that is the only it's advantage as a method to make your program flow more human-visible. We do not have any specific suggestions on using it for debugging. The recommended way to debug code on an S32G2 processor is to use a GUI-based debugger in combination with a JTAG probe. The information on available tools can be found on S32G2 product page.
