i.MX6 Warning IPU_INT_STAT_10 = 0x00080000

宗標廖 · ‎01-28-2015

Hello

Qiang Li

I am now working on i.MX6DL with L3.0.35, and when we are playing video,we got a warning

"imx-ipuv3 imx-ipuv3.0: IPU Warning - IPU_INT_STAT_10 = 0x00080000", when the waring occured,

it appeared some color lines above the video view.(Frequency is very low).

Though I found many similar issues in the community(includes Re: imx6 android 4.3.1 IPU error when system start),

I did not find a solution for me.According to page 3174 of the IMX6SDLRM,there is discription for bit19 as below,

This bit indicates on the interrupt that is a result of an error during access to a synchronous display via DI0.

So could you tell me what kinds of error can cause the interrupt? And could you give me some advice to resolve

this problem?

I attached the kernel config file, u-boot config file and u-boot env settings

Thank you!

Best Regards,

ZongbiaoLiao

We are checking internally your issue, we will get back to you soon.

Hello.

I am also having a similar problem. i was using gstreamer for capture 1080p at 30 fps and display at 1080p at 60 fps.

I get the same IPU_INT_STAT_10 error. could increasing the IPU signal help solve the problem. it would also change the pixel clock. What would be the maximum frequency for the IPU_DI clocks?

zctee · ‎06-03-2015

Hi,

I face the same issue also.

My issue occurred after unblanking the display from blank mode. kernel log shows:

imx-ipuv3 imx-ipuv3.0: IPU Error - IPU_INT_STAT_10 = 0x00080000

imx-ipuv3 imx-ipuv3.0: IPU Error - IPU_INT_STAT_5 = 0x00800000

It only happens to bigger resolution screen. i tested on 1280x1024, 800x600, 800x480, only the 1280x1024 have this problem.

I am using kernel 3.0.35 as well.

If you guys found the solution, please advice me.

Thank you.

Regards,

ZC

When memory loading is heavy, there is chance that IPU DI can't access memory on time, then such error will appear.

You can add the followed register setting in uboot file flash_header.S, it will enable AXI cache and give IPU high priority to access AXI bus. This is the default setting for 3.10 BSP.

/* enable AXI cache for VDOA/VPU/IPU */

DATA 4, 0x020e0010, 0xF00000CF

/* set IPU AXI-id0 Qos=0xf(bypass) AXI-id1 Qos=0x7 */

DATA 4, 0x020e0018, 0x007F007F

DATA 4, 0x020e001c, 0x007F007F

For example in 3.0.35 uboot, u-boot-2009.08\board\freescale\mx6q_sabresd\flash_header.S

- dcd_hdr: .word 0x40a002D2 /* Tag=0xD2, Len=83*8 + 4 + 4, Ver=0x40 */

- write_dcd_cmd: .word 0x049c02CC /* Tag=0xCC, Len=83*8 + 4, Param=0x04 */

+ dcd_hdr: .word 0x40b802D2 /* Tag=0xD2, Len=86*8 + 4 + 4, Ver=0x40 */

+ write_dcd_cmd: .word 0x04b402CC /* Tag=0xCC, Len=86*8 + 4, Param=0x04 */

... ...

MXC_DCD_ITEM(83, MMDC_P0_BASE_ADDR + 0x01c, 0x00000000)

+ MXC_DCD_ITEM(84, 0x020e0010, 0xF00000CF)

+ MXC_DCD_ITEM(85, 0x020e0018, 0x007F007F)

+ MXC_DCD_ITEM(86, 0x020e001c, 0x007F007F)

zctee · ‎06-03-2015

Hi QiangLi,

I checked my flash_header.S, the original DCD item 0x020e0010 is set to 0xF00000FF already. 0x20e0018 and 0x20e001c is set to 0x007F007F already

Nethertheless, i tried to change 0x020e0010 to 0xF00000CF and test, the IPU error still happens.

Any other recommendations? I am using spl0 display mode. Thank you.

Regards,

ZC

qiang_li-mpu_se · ‎06-04-2015

What's your use case?

zctee · ‎06-04-2015

Hi QiangLi,

In my use case, i boot up the board in 1280x1024 display with touch screen.

After 2 minutes of idle, the machine will blank the screen and turn off the backlight.

When user touch the screen, the machine will unblank the screen and turn on the backlight.

The IPU error happens when the machine unblank the screen. I had been suspecting whether other process will be causing this, so i do a script simply to blank and unblank the display every 2 minutes. Doing so, sometimes the IPU error will happens too.

Regards,

zc

qiang_li-mpu_se · ‎06-04-2015

Hi zz, your issue is not bandwidth issue, it is more like you had changed some IPU code to wrong.

Will you get the error every time for the followed test command?

# echo 1 > /sys/class/graphics/fb0/blank

# echo 0 > /sys/class/graphics/fb0/blank

zctee · ‎06-04-2015

Hi QiangLi,

Yes, these are the command that i used in the script to blank/unblank the display. IPU error will occurred sometime when issue the command to unblank the display. no error when blanking display.

One thing i noted is that the IPU error only happens on bigger screen. We have 3 type of screen. the blank/unblank works find in 800x480, 800x600, but failed on 1280x1024.

The IPU code is not changed. But is it possible some bug in kernel version 3.0.35?

Thank you.

Regards,

zc

qiang_li-mpu_se · ‎06-04-2015

How did you add your display mode timing parameters for your 800x480, 800x600, and 1280x1024 resolution?

zctee · ‎06-04-2015

Hi QiangLi,

I believe you are refering to the left right margin, pixclk, etc parameter?

We do it by using config flag that is set in menuconfig. the config flag will set the parameter accordingly in /drivers/video/mxc/ldb.c

static struct fb_videomode ldb_modedb[] = {

{

#if defined(CONFIG_LCD_1280x1024)

"LDB-XGA", 50, 1280, 1024, 15770,

120, 20, //left right margin

20, 12, //top bottom margin

10, 10, //h-len v-len

#elif defined(CONFIG_LCD_800x600)

"LDB-XGA", 50, 800, 600, 30770,

50, 10, //left right margin

5, 12, //top bottom margin

10, 10, //h-len v-len

#elif defined(CONFIG_LCD_800x480)

"LDB-XGA", 50, 800, 480, 30770,

50, 10, //left right margin

5, 12, //top bottom margin

10, 10,

#endif

0,

FB_VMODE_NONINTERLACED,

FB_MODE_IS_DETAILED,

},

{

"LDB-1080P60", 60, 1920, 1080, 7692,

100, 40,

30, 3,

10, 2,

0,

FB_VMODE_NONINTERLACED,

FB_MODE_IS_DETAILED,

},

};

Besides this, in /drivers/video/mxc/ldb.c, function ldb_setup, set lcd interface to spl0:

#if defined(CONFIG_LCD_1280x1024)

g_ldb_mode = LDB_SPL_DI0;

#endif

set the LCD interface to spl0.

in drivers/video/mxc/mxc_ipuv3_fb.c, function mxcfb_option_setup, set color mode to RGB24:

#if defined(CONFIG_LCD_1280x1024)

pdata->interface_pix_fmt = IPU_PIX_FMT_RGB24;

continue;

#endif

Is there anymore parameter that i should set?

Thank you.

How about your kernel boot up log?

zctee · ‎06-04-2015

Hi QiangLi,

Kernel boot up log does not show any IPU error.

IPU error only happens after the unblanking.

I am not sure how to attach the kernel log in here, so i cut and paste it over.

Hi ZC, you had enabled two lvds display in boot command, that should be the issue, for SPL0 mode, the two LVDS ports need be used. Please try the followed command line:

video=mxcfb0:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb1:off ldb=spl0

Hi ZC, I think your 3.0.15 BSP is too older to support split mode of LVDS display, you'd better update to 3.0.101_4.1.1 BSP.

Embedded Linux for i.MX Applications Processo|Freescale

I had tried your LVDS display timing parameters on it, there is no IPU ERROR issue.

zctee · ‎06-07-2015

Hi QiangLi,

That indeed is a bad news. May i know is there any workaround for me to bypass this problem?

Thank you.

Regards,

ZC

qiang_li-mpu_se · ‎06-07-2015

The error should be related with ldb, IPU and clock drivers, but it is hard to identify it.

zctee · ‎06-07-2015

Hi QiangLi,

May i know when i perform:

# echo 1 > /sys/class/graphics/fb0/blank

# echo 0 > /sys/class/graphics/fb0/blank

what exactly does the kernel do besides setting the blanking in mxcfb_blank?

Regards,

ZC

qiang_li-mpu_se · ‎06-07-2015

blank and unblank fb0, it will disable IPU display and re-enable IPU display.

There should be no error as followed:

[ 105.954563] imx-ipuv3 imx-ipuv3.0: IPU Error - IPU_INT_STAT_10 = 0x00080000

[ 105.954649] imx-ipuv3 imx-ipuv3.0: IPU Error - IPU_INT_STAT_5 = 0x00800000
