hi ,

I have a imx6slevk and a 10.3 inch epdc display (es103tc1).

my software enveriment is L4.1.15_2.1.0-ga.

I use the stress test cmd as follow "/unit_tests/mxc_epdc_fb_test.out -n 14".

the fault information is "TCE underrun ...".

Is the 10.3 inch display could't pass the stress or my soft set error.

thanks a lot.

Hello yan2 anfei,

The unit test as is works with the default EPDC module  (IMXEBOOKDC3-E) which is compatible with the i.MX6SL EVK. To make it work on your board you would need to obtain the waveform for your panel from your manufacturer and parse it for the i.MX6SL. You may open a support Case to get the waveform parsed for you.

Besides this you would need to add the timing structure for your panel and desired resolution to the EPDC driver. You should also receive the timing from the EPD manufacturer.

I hope this helps!

Regards,
