The problem was with my printk_plugin. I didn't have the the correct variable arguments setup, and when I was printing, the values for the format string were memory areas not assigned to the variables. Now that I'm passing the variable arguments, the stack
checker appears to be working well.

That doesn't seem right at all. Calling the "with plugin" variant requires you<br class="">
to pass something that has a signature like fprintf(). Did you call that method<br class="">
directly or via the wrapper rtems_stack_checker_report_usage()?<br class="">
<br class="">
Can you run the fileio sample and try the stackuse command? That test should<br class="">
just work.<br class="">
