<p class="MsoNormal">Hi all,<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB">I’m interested in getting stack information via an UDP message with an ASCII log trace inside. 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):</span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB"> </span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB">static int logPlugin(void *context, const char *format, va_list ap)</span><u></u><u></u></p>

<p class="MsoNormal"><span lang="EN-GB"> (void) context;</span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB"> return addLog(INFO, STACK,format, ap); /* First two arguments are used to classify message at reception*/</span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB">}</span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB"> </span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB">Then at rtems_stack_checker_report_usage_with_plugin calling scope:</span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB"> </span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB"> rtems_printer printer;</span><u></u><u></u></p>

<p class="MsoNormal"><span lang="EN-GB"> </span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB">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.</span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB"> </span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB">When stack checker report usage is called, only the information header is printed: " STACK USAGE BY THREAD\n"</span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB"> "ID NAME LOW HIGH CURRENT AVAIL USED\n"</span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB"> </span><u></u><u></u></p>
<p class="MsoNormal"><span lang="EN-GB">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?</span><u></u><u></u></p>
