LCD blank screen issue RRS feed

  • Question

  • Hi.

    I am facing a issue in WEC7. The issue is LCD goes blank once out of 100 or more times boot. I printed IPU registers, there are differences in both the cases. Different values when normal working and blank screen issue.

    Could someone give idea about this? 

    Regards,

  • Hi,

    CCM init was done properly along with some DDR calibration values and issue is resolved.

    Thank you for the support.

  • Well, first of all; spell out the differences (and with that I do not mean just the values, but look up the meaning of the bits in the reference manual).

    I assume you are talking iMX here, which processor?


    Good luck,
