Hello
I had a bad feeling about stack usage (perhaps measurement), and I have
written a small testcode, to see what's really happening. It came with
an interesting result. It seems to me, that
cyg_thread_info.stack_used gives the max used stack size, not the
actual. Is that right? According to the docs, it should give the current
usage.
The test code is attached, I use arm-elf-gcc, ecos with default packages.
The result is also attached. I think that even the last stack usage
should be equal with 144 Bytes.
Maybe I am wrong... maybe not.
Thank you!
