Subject: Re: [Bug Report] DU: Error messages at boot log and can't show image on RGB Display.
Date: Wed, 13 May 2015 06:43:36 +0000 [thread overview]
Message-ID: <5552F298.2020201@jinso.co.jp> (raw)
Hi All.
We are testing Linux upstream version-4.1-rc2 on Lager.
We found a Error message of DU(Display Unit) at boot logs:
The Warning messages is showed as below:
"rcar-du feb00000.display: encoder initialization failed, skipping"
Then we tried to show a .bmp image on RGB Display via RGB port. But it
didn't work.
Testing method:
1. Connect RGB Display to RGB port on Lager.
2. Show a BMP image on Display by this command:
# bmap /dev/fb0 ./image.bmp
We'd like to report this problem first.
There are no error message at version v4.0 stable.
And showed the image on RGB Display normally at version v4.0 stable.
We are looking for the error patch that added between v4.0 and v4.1-rc2.
Best Regards,
Jinso/Cao Minh Hiep.
