Basically, I cannot get the information using a printf. I found the function rtems_stack_checker_report_usage_with_plugin(rtems_printer* printer) in order to get the information and send it using my UDP log function. So first of all I created a function called logPlugin (I used as exampled the plugin at printf_plugin.c): static int logPlugin(void *context, const char *format, va_list ap) { (void) context; return addLog(INFO, STACK,format, ap); /* First two arguments are used to classify message at reception*/ } Then at rtems_stack_checker_report_usage_with_plugin calling scope: rtems_printer printer; printer.context = NULL; printer.printer = logPlugin; rtems_stack_checker_report_usage_with_plugin(&printer); It is important to say that addLog puts the message in a circular buffer that other task will read and send the content using UDP. When stack checker report usage is called, only the information header is printed: " STACK USAGE BY THREAD\n" "ID NAME LOW HIGH CURRENT AVAIL USED\n" Next, stack values are not printed correctly and I can only get a value that is constant and equal to the same memory location (in decimal). It is a correct guide to implement this? I do not know how to use the printer struct context variable, can this cause my problem? Did you add CONFIGURE_ENABLE_STACK_CHECKER? Yes, it was enabled. Also it would be handy to have methods for obtain cpu and stack usage without relying on the printf hook I developed a code to gather all the tasks stack information into a struct that can be retrieved via function. Then I pack this struct and sent it via Ethernet. Can I add my code to check.c in order to retrieve stack information without print it? Is this an intersesting feature for the community?
