Subject: [ECOS] Bad ASSERT check in check_stack?
Date: Thu, 07 Feb 2013 05:52:00 -0000 [thread overview]
Message-ID: <CAOFa9c1-KuNkvrHA7XFySSk5ZM7Eb6NDBqXqmHYJKZa_tCTD8w@mail.gmail.com> (raw)
Hi all,
I get the following assert ("ptr below base") in my application (I
added the prints before the assert)
stack_base 0x80045a88 base 0x80045a68
stack_ptr 0x80045a30 top 0x80046048
ASSERT FAIL: <B>thread.inl [ 112] <nofunc>()
The faulty thread is B(ETH) but the stack_base belongs to the idle thread.
in addition the TRACE_PRINT() that prints the threads info prints different data
Idle Thread pri = 31 state = R id = 1
stack base = 80045a68 ptr = 80045b28 size = 00000600
sleep reason NONE wake reason NONE
queue = 00000000 wait info = 00000000
**********************************************************************************************************
I checked the location of the "stack_ptr 0x80045a30" it is located in
inside the idle_thread object.
The idle thread stack is located after the thread object.
I'm wondering if this assert is doing it's job?
It looks like the the "stack_base" is checked against some random
"stack_ptr" value.
Any ideas?
thanks
Elad
