Linux/AM5728: Kernel crash issue

Part Number: AM5728
Other Parts Discussed in Thread: TMP102, TMDSEVM572X, TLV320AIC3104

Tool/software: Linux

The kernel crash issue on AM5728+Linux platform:

Hi, I'm david, I made a board based on AM5728 platform, and running Linux on that, but system crash problem hasbeen bothering me.

I modified the content in TI standard SDK(version 4.0.0.4) as follows:

1. U-Boot: modified board id related parts, because my board has no eeprom(include board info), It seems that U-Boot booting is normal.

2. Linux Kernel: arch\arm\mach-omap2\pm.c

int __init omap2_common_pm_late_init(void)

{

......

/* Init the voltage layer */

omap_pmic_late_init();

#if 0

omap_voltage_late_init();

/* Initialize the voltages */

omap3_init_voltages();

omap4_init_voltages();

#endif

/* Smartreflex device init */

omap_devinit_smartreflex();

#if 0

/* cpufreq dummy device instantiation */

omap_init_cpufreq();

#endif

return 0;

}

3. Device Tree(am57xx-evm-rev3a.dtb): A little Modification, disable some hardware, because my board use different RTC chip, has no LCD and temperature sensor(tmp102).

Help me,please!

Part of the startup information content as shown below:

Hi David,

From the log file you have provided, the crash seems to be caused by rootfs misconfiguration, not linux kernel problem.

The error seems to be related to the below exe file:

tisdk-rootfs-image-am57xx-evm/usr/bin/php-cgi

Have you made any modifications of the AM57x rootfs? Can you check with the default one that come with PSDKv4.00?

ti-processor-sdk-linux-am57xx-evm-04.00.00.04/filesystem/tisdk-rootfs-image-am57xx-evm/

Can you also check what will be the result of the booting process if you use arago minimal rootfs?

Hi, Pavel

First of all, thank you for your patience.

But I can tell you that I have never modified file system,and I use full file system(tisdk-rootfs-image-am57xx-evm).

I use SDK_PATH/bin/create-sdcard.sh script to generate booting SD card,and at this point, I selected default file system(prebuilt-image), so I don't think the problem is in the file system.

I've been doing experiments with the old version（V3.3.0.4） these days,booting process(include weston and matrix-gui-2.0) was good,but some examples of Matrix (such as OpenCL samples) running caused system crash too.

I'm wondering about two points：

1. There maybe some problem with in Device Tree File.

2. There may be hardware problems,But I'm not sure...

Thanks

Best Regards,

David. Jo.

David,

Can you also check what will be the result of the booting process if you use arago minimal rootfs?

ti-processor-sdk-linux-am57xx-evm-04.00.00.04/filesystem/arago-base-tisdk-image-am57xx-evm/

If you can not crash the kernel with that arago rootfs, then most probably the issue is not related to kernel and/or DTS.

processors.wiki.ti.com/.../Processor_SDK_Linux_Filesystem
processors.wiki.ti.com/.../Customization

You can also check for DDR3 issue, running DDR3 memory tests.

Pavel

Hi, Pavel

I think your suggestion is very good,but I never changed the file system,except for the applications I wrote.

I 've checked the result with minimal rootfs follow your advice, booting process is good, but minimal system has no graphical tools ,such as weston,matrix. etc.

These two days, I did a series of experiments as follows:

1. I decided to use old SDK version(3.3.0.4), I only modified some files of u-boot and DTS file according to my custom board.

The System(SD card) booting are well in both the TI development board(TMDSEVM572X) and my custom board. It's exciting to see that the Weston and Matrix app are starting up normally.

That means the old version（3.3.0.4） is more stable than newer version(4.0 and 4.1), at least for my board.

2. But...Some of the matrix-gui sample programs are running normally,but some are not(causing the system to crash).

Some samples of Matrix(ARM,3D,Power, Qt...) are running normally.

But some samples failed, and even caused the system to crash. <Open CL / Vector Addition> is one of them.

And My App(reading the USB camera) also caused the system to crash, but it works well in the TI development board.

Here is the print message at runtime of <Matrix / Open CL / Vector Addition>：

From what I understand, this sample application (Matrix / Open CL / Vector Addition) runs fine on the AM572x TI EVM but fails on your custom board.

Could you please provide more info regarding this sample application? Do you take it from some place or you made it?

What are the HW differences between AM572x TI EVM and your custom board?

I would suggest you to start with DDR3 memory tests. Check the below e2e threads for pointers:

Pavel

Hi，Pavel

Thank you for your quick response，Your understanding is correct.

This sample（Standard examples provided by TI SDK, path: OpenCL->veadd example）runs fine on the AM572x TI EVM but fails on my custom board.

HW differences between AM572x TI EVM and my custom board are as follows:

- my board has no LCD, EEPROM, TLV320AIC3104,PCIE,thernet 2.

- use RTC chip-PCF8563T instead of MCP79140.

- No use USB hub chip, usb power chip is different.

Can you recommend a good way to test DDR3?

The attached files are my modified DTS files(Most of them only are disable some functions)

Thanks.

Regards

David. Jo.

Hi, Pavel

I'm looking forward to your help. The results of memory test on the custom board are as follows:

I've used memtester tool:

target# memtester 1G 1

TI standard kit board runs well during the test:

Done.

But my custom board is'nt well...

[   36.748779] Unhandled fault: synchronous abort (translation table walk) (0x217) at 0x05ee04aa

The system crashed before the test started

And I've measured the voltage of DDR3. It's normal.

I found that once the memory test started in the TI development board, the voltage of the DDR3 dropped a little bit,but there was no change in my board.

Do you think this is a H/W problem or a S/W problem?

Thanks!

Best Regards

David. Jo

David,

Could you please clarify what are the difference in DDR3 design ans size between AM572x TI EVM and your custom board?

Please go through the below links for more info regarding DDR3 config:
