PROCESSOR-SDK-AM335X: Framebuffer control causes kernel panic

user6237390

Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3352, TPS65910, AM3354

Hi,

We want to show images in panel and change the image every 5s. However, we always got kernel error messages after few minutes. We just write a simple script with the cat command or using ioctl to implement the function.

Hello,

I am wondering if you could please share more information about the custom script. Also, if you remove the script from the system service, are you still experiencing Kernel panics? As an experiment, please launch the script after the login prompt to see if the panic still exists.

Regards,
Krunal

Hi Krunal,

We did some tests as follows:

Change image every 5 sec. (script or ioctl ) => system crash.
Just show one image => everything is fine.
Open/Close framebuffer every 5 sec. => after few minutes, can’t unblank panel. (But system doesn’t crash

Script content as below:

=================Script========================

#!/bin/sh

num=0;

while true
do

if [ $num -eq 0 ]; then
cat /root/standby.raw > /dev/fb0
num=1
sleep 5
elif [ $num -eq 1 ]; then
cat /root/plug.raw > /dev/fb0
num=2
sleep 5
else
cat /root/charging.raw > /dev/fb0
num=0
sleep 5
fi

done

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

Thanks

I attached DTS and script at Dec 3

Please reply me ASAP, if you got any idea.

Thanks

Hello,

Could you please share the Kernel panic with the following symbols enabled: CONFIG_DEBUG_KERNEL=y and CONFIG_FRAME_POINTER=y?

Already enable by default config.

Hi Krunal.

Compare the boot log with AM335x Started Kit. Our log missing the below highlight part. Does it effect the lcd control?

I set log level (echo 7 > /proc/sys/kernel/printk) before test LCD. Please reference the attachment.

Hello,

Does your application work on the AM335x Started Kit?

Hello,

I am wondering if you have any updates and are you able to replicate your issues on a TI board?

Hi Krunal,

I run our task overnight in AM335x start kit and it work well.

The attachment is the memtester log in our board (AM3352). It seems abnormal.

Thanks.

Hi Jason,

I am wondering if the memtester fails without the tilcdc. Also, is the display fully functional and are you able to run applications like kmscube/matrix-gui?

Regards,
Krunal

Hi Krunal,

In our board, we will get kernel panic after run gui applications 30 min or 1 hour. However, it works well in start kit. Why memtest show a lot tilcdc information?

Can we solve the kernel panic problem, if we change the MPU to AM3354?

Btw, we using MT41K256M16TW 4Gbit DDR3L.

Thanks.

Hello,

Could you please disable tilcdc and run the memtest? Before we debug any display/graphics problem, lets make sure the DDR is stable.

Regards,
Krunal

Also, please share the EMIF tool values that were generated for your custom DDR part.

Hi Krunal,

I think TI's SDK support this DDR3L. The memtest show ok now, after we add ocp_config in u-boot. However, the kernel panic issue still happened.

Do we need to change the value of EMIF_OCP_CONFIG_AM335X_EVM ?

Thanks

All custom designs need to use the AM335x EMIF tool spreadsheet: https://www.ti.com/lit/pdf/sprack4 to properly configure the DDR. Please read this appnote and follow the directions to complete the spreadsheet, then use the resulting values in your code.

Most likely you have a sub-optimal DDR configuration which is causing your kernel panics.

James

Hi James,

We finish SW leveling and rebuild the MLO & uboot.img.

Summary :

1. With SW leveling -> segmentation fault after a few minutes, but no kernel log.

2. No SW leveling, but with ocp_config -> kernel panic after 4-5 hours.

3. AM335x Starter Kit -> 1 day no error

I have no idea...

Any ideas on what we should do?

Please send the completed spreadsheet for your design and the patch file of the changes you made to board.c based on the spreadsheet output. If you only have one DDR memory component, you do not need to run the software leveling algorithm.

Regards,

James

-> We only have one DDR memory component. Why TI's FAE tell us must to do software leveling ... Who is right?

Also, we find that if we run LCDTask without insert LCD, it can run overnight well. Do you have any ideas?

Thanks

Hello,

For a single DDR memory, the software leveling is no longer required. Before we debug the LCD issues, we need to ensure that the memory is stable and configured correctly. As James recommended in the following post, please fill out the AM335x EMIF tool spreadsheet and update the Uboot code.

Regards,
Krunal

Please follow the directions in the app note with the link provided previously. The app note explains how the changes should be made in board.c, not ddr_defs.h. After completing the spreadsheet, please provide the spreadsheet and the board.c diff file.

Regards,

James

Hi James,

LCDC seams well now, after we follow https://www.ti.com/lit/an/sprack4/sprack4.pdf to modify u-boot’s board.c and without SW leveling.

Thanks
