hai,yuri,I reduce the frame rate from 60 to 50,but it is not work ok.
It is needed to consider the system in whole - perhaps the system is overloaded.

Yuri.
well,i see there has a patch for the IPU_INT_STAT_5 = 0x00800000,does it suit my problem?
by the way ,we have usb and ethernet/bt/wifi, have no camera.
at the same time,the BT and wifi ethernet is no connect with ipu, how can that affect my display moudle?????
Dear yuri,i have try this ,but it is not work,there still have ipu warning.
If You use one display, You can add "dmfc=3" in kernell boot command line.
This can let the single display use all of the DMFC FIFO.

Yuri.
dear yuri,i have add it to the cmd,but there still have the warning.but still thank you for your help.
You may try using recent BSP(s).
Regards,
Yuri.
Dear yuri:
how to try the new bsp?will it have a lot change?
You may find demo images (.sdcard fime extention), such as
" fsl-image-gui-x11-imx6qdlsolo.sdcard" for the recent BSP (L3.14.28)
in the following bundle.
http://www.freescale.com/webapp/Download?colCode=L3.14.28_1.0.0_iMX6QDLS_BUNDLE
Please use the next Linux command to copy it to SD card :
$ sudo dd if= ./fsl-image-qt5-x11-imx6qdlsolo.sdcard of=/dev/sdb bs=1M
Dear yuri,I the bsp download always fail,i will try again,
but something confuse me:
our project use mfg tool to download,i want to know what the relationship of boot.img and BSP?
in fact,maybe we have different called about bsp. can you tell me what the meaning of your meaning about BSP?
I meant, You may prepare boot SD card under host Linux :
$ sudo dd if= ./fsl-image-qt5-x11-imx6qdlsolo.sdcard of=/dev/sdb bs=1M

Yuri.
