We have tried to use IMX6QuadPlus with two framebuffers (fb0 : background and fb1 :overlay) with the resolution 1080p@60Hz but we have some errors :

 

imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000
imx-ipuv3 2800000.ipu: IDMAC21's U offset is not 8-byte aligned
imx-ipuv3 2800000.ipu: IDMAC21's V offset is not 8-byte aligned
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x08800000
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000

.....

imx-ipuv3 2400000.ipu: warning: wait for bg sync eof timeout
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_5 = 0x08800000
imx-ipuv3 2400000.ipu: IPU Warning - IPU_INT_STAT_10 = 0x00080000

 

When we use only one buffer we have no problem or if we use 720p@60Hz we can use two framebuffers
