iMX53 IPU DI error interrupt

[torus1000]

Hi all,

Now I'm debugging my board and my IPU test program for LCD display.

Then I got DI0_SYNC_DISP_ERR interrupt but manual indicated it was DI0 error and
I couldn't see any hints to avoid this error.

Does anyone advice me which cases mostly this error occured?

How can I avoid this error in those cases?

Thanks.

Hi torus1000

this error means that IPU has not sufficient performance capability due to

incorrect IPU settings or too big image. Please look at

DI0_SYNC_DISP_ERR is IPU_INT_STAT_10[19] according to

Table 45-34. Error Interrupts Summary IMX53RM

One can try solution below for such kind of error

mxc_ipu mxc_ipu: IPU Error - IPU_INT_STAT_10 = 0x00080000

Best regards

igor
