thank you so much.

by the way ,can you tell me about how to solve ipu_warning:

<4>[ 1.983397] imx-ipuv3 imx-ipuv3.0: IPU Warning - IPU_INT_STAT_5 = 0x00800000

<4>[ 1.990512] imx-ipuv3 imx-ipuv3.0: IPU Warning - IPU_INT_STAT_10 = 0x00080000

does this warning effected by the ipu/lvds clk settingt?

Hi尚飞汤

IPU_INT_STAT_10 =0x00080000"

this bit is set as result of data starvation when

data that should be sent to display, but it is not available in IPUs

internal FIFO.

Most probable cause for this issue is huge load on the DDR memory bus.

One can try to decrease bus load: remove unused applications, decrease frame

rate,

bpp (bit per pixel), increase ddr and processor frequency, if possible.

well，it is so professional analysis.

however,could it be caused by the ipu/lvds setting

and how about the IPU_INT_STAT_5 = 0x00800000 warning probable be caused?
