Hi
I am seeing the following message during the boot:
imx-ipuv3 imx-ipuv3.0: IPU Warning - IPU_INT_STAT_10 = 0x00080000
According to the reference manual for IMX6 this is releated to "display controller error channel 1" when the anti tearing effect is enabled.
Do you have idea how I can fix this ? I am using Android
I will try.. but do you know ? it is odd.. I noticed this warning appears sometimes.. how come ?
also may be recommended to decrease bus loading (for example
reduce lcd fps or resolution) and avoid to use IPU IC.
Best regards
igor
Hello
Please someone has any insight ?
I am using the following command line:
Kernel command line: console=ttymxc0,115200 init=/init video=mxcfb0:dev=lcd,Newhaven-LCD,if=RGB24,bpp=32 fbmem=28M fb0base=0x27b00000 vmalloc=400M androidboot.console=ttymxc0 androidboot.hardware=intrinsyc no_console_suspend=1 dmfc=3
however, the IPU warning happens sometimes only.
Hi Manoel
please try the 'dmfc=3' kernel boot-up command option. This would increase display FIFO size.
Best regards
igor

False alarm.. I still have
imx-ipuv3 imx-ipuv3.0: IPU Warning - IPU_INT_STAT_10 = 0x00080000
Can you clarify what dmfc means ?
