Hi
I have custom board with a Gumstix Overo, my board is similar to a
Tobi board. Right now i have it running with a 3.5.0 kernel. I'm
trying to upgrade the kernel, and have tried several versions (3.10 ->
3.15) and i seem to be hitting the same problem with all versions, i
get random crashes. Found a way to trigger the crash within
minutes/seconds:
# dd if=/dev/urandom of=/tmp/test.file bs=1024 count=100000
A count > 10000 will at some point trigger the crash. The hang/crash
is repeatable everytime but the log is not, sometimes i do not get
any trace at all. I can provide more logs if necessary. Config and
crash log are below..
Have tried disabling various peripherals, such as sound, usb,
ethernet, wifi, bluetooth, but with no luck. Also tried different Overo
boards.
Hope someone can help me/point me in the right direction

I was seeing similar issues with NFSroot until commit dcf21919
(ARM: dts: Fix GPMC timings for LAN9220). Turns out LAN9220 has
much slower timings compared to LAN9221. So you need to check that
you're using right timings if you have LAN9220.
Also, check what rate your bootloader is setting the L3 speed.
If it's set to 200MHz, then LAN9220 timings seem to overflow the
GPMC registers for the calculated values and bootloader timings
are used instead.

Hi
U-boot seems to set the speed to 165 Mhz
"OMAP36XX/37XX-GP ES1.2, CPU-OPP2, L3-165MHz, Max CPU Clock 1 Ghz"
I have a LAN9221, but tried the other timings, still same result.
Also tried running the entire system from an MMC card, same result, but my test had
to run a little longer.
Found a quicker test to reproduce the error, a little C-program:
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
int main(void){
long long var=0;
int *ptr=NULL;
int run=1;
while(run){
ptr=malloc(sizeof(int)*1000);
if(ptr==NULL){
run=0;
}
var+=1000;
printf("mallocsize = %lld\n",var*sizeof(int));
}
}
Booting from NFS, the system crashes at ~40mb allocated
On MMC at ~60MB
Med venlig hilsen/Best regards

Hi Casper,
What is the top-side marking on the memory chip on your Overo? There
were some random faults due to poor memory chips marked 'JW513' from
about 18 months ago.

Hi
The memory on the Overo, i have with me right now, is actually marked JW513,
and 18 months is also around the time, they were bought. Will check my other
modules, when i get back to the office.
However i have not been able to recreate the problem with the 3.5.0 kernel on
same Overo
Med venlig hilsen/Best regards

Hi again
All my boards are marked "JW513". So the problem might be hardware related, i will try to get some new Overo's and test on these instead.
Med venlig hilsen/Best regards

Hi
The memory on the Overo, i have with me right now, is actually marked JW513,
and 18 months is also around the time, they were bought. Will check my other
modules, when i get back to the office.
However i have not been able to recreate the problem with the 3.5.0 kernel on
same Overo
Med venlig hilsen/Best regards

Hi Casper,
What is the top-side marking on the memory chip on your Overo? There
were some random faults due to poor memory chips marked 'JW513' from
about 18 months ago.

OK, please let us know how it goes.
Also if using armhf based distro some omap3 SoCs need
CONFIG_CPU_BPREDICT_DISABLE=y or CONFIG_ARM_ERRATA_430973=y
or both. Sorry no idea yet which revisions, but I've seen some
flakeyness with apt-get dist-upgrade occasionally failing
on a 3630 with revision info:
CPU: ARMv7 Processor [413fc082] revision 2 (ARMv7), cr=10c5307d

Hi
I got two new Overo AirStorm today, and they have same behavior. I tried disabling
the SMSC9xxx again and booted from MMC. This seems to make the backtrace a
little more consistent(Tried on both new and old). There is (almost) always something
about Alignment trap, the crash log itself differs every time. Also i get to allocate a lot
more memory before crash with these settings.
mallocsize = 34460000
mallocsize = 34464000
mallocsize = 34468000

Hi
The memory on the Overo, i have with me right now, is actually marked JW513,
and 18 months is also around the time, they were bought. Will check my other
modules, when i get back to the office.
However i have not been able to recreate the problem with the 3.5.0 kernel on
same Overo
Med venlig hilsen/Best regards

Hi Casper,
What is the top-side marking on the memory chip on your Overo? There
were some random faults due to poor memory chips marked 'JW513' from
about 18 months ago.

We should have v3.15 working fine, but PM features are not merged
in util for v3.16.
I would try dding calls to omap_sdrc_init to pdata-quirks.c
the same way board-over.c is doing:
omap_sdrc_init(mt46h32m32lf6_sdrc_params,
mt46h32m32lf6_sdrc_params);
If the memory timings are not correctly set by the bootloader
that could explain the issues.

Tony

Hi
You are right. I used a different bootloader for the newer kernels, because of
another build system and did not think about it. The u-boot from github/gumstix
sets the memory timings different than the u-boot directly from denx.de.
I switched to the gumstix-uboot and i can now allocate all the memory in the system
with all peripherals enabled, and i just get killed by the OOM a some point.
But thanks for the help so far, even though it was not a kernel issue :-)
Med venlig hilsen/Best regards
Casper Mogensen
