Is too big of a span (4 weeks) - can you narrow it down to a day (by bisecting

things)?

-Robin

--- Vivi Li 2009-07-13 03:23:56

I tried and found that it failed since kernel version 6253. 6252 is fine.

--- Mike Frysinger 2009-07-13 03:27:27

really ? 6253 is tweaking Kconfig for EXCEPTION_L1_SCRATCH and you should end

up with the same binary there ...

if you build 6253 with EXCEPTION_L1_SCRATCH set to n, does it still fail ?

--- Vivi Li 2009-07-13 04:27:02

Sorry, I don't find EXCEPTION_L1_SCRATCH in linux-2.6.x/.config.

--- Robin Getz 2009-07-13 08:02:14

It's easy to find out what is going on...

help

Whenever an exception occurs, use the L1 Scratch memory for

stack storage. You cannot place the stacks of FLAT binaries

====================

In my default .config, I have:

CONFIG_APP_STACK_L1=y

Since we allow application stacks in L1 - this option does not show up. It is

not likely that this causes the bug...

--- Sonic Zhang 2009-07-15 02:38:31

Not a bug. The fragment test allocates 16856k bytes from system memory. The

recent kernel and ramfs occupied too much memory on bf533-ezkit witch has only

32M SDRAM. The solution is to disable some applications and kernel useless

drivers before run this fragment test.

--- Vivi Li 2009-07-26 23:59:18

Release more memories for this case. It's the same problem for ltp test in

bf533-ezkit.

Fix it in test script.

--- Vivi Li 2009-08-06 07:14:13

OK, Close it.
