<div>Hi,<br>
<br>
Has the stack usage of rtems_clock_tick() ever been (roughly) computed at the maximum depth of the callstack ? the BSP's seem to vary quite a bit from 1k to 4k for the interrupt stacks.<br>
<br>
A while back i used <a href="http://stackcheck.pl">stackcheck.pl</a> by Dan Kegel,
<a href="http://www.kegel.com/stackcheck/">http://www.kegel.com/stackcheck/</a> it gives you the stack usage of each function, but it would still be quite a bit of effort to add them up to the maximum depth.<br clear="all">
