hai,yuri,I reduce the frame rate from 60 to 50,but it is not work ok.

[Yuri]

It is needed to consider the system in whole - perhaps the system is overloaded.

Dear yuri,i have try this ,but it is not work,there still have ipu warning.

[Yuri]

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.

Dear yuri：

[Yuri]

  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?

[Yuri]

   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.

Dear yuri  ：

我发现15寸的有这个问题，但是七寸和十寸的都没有这样的问题。

如果使用最新的BSP是否会涉及很多改动？我司这边项目已经进行到了一半了
