Description

Hardware: GTA01Bv03
u-Boot: 2040
Kernel: uImage-2.6-moko10-r0_0_2006_0-fic-gta01.bin

With the above mentioned kernel from buildhost, the backlight does not work any
more.

/sys/class/backlight/gta01-bl exists, and the files do exist also.
But despite the backlight being on in reality, the (actual_)brightness files say

  1. and echoing "1000" into them doesn't change anything.

I see that, too.

  • Status changed from new to closed
  • Resolution set to fixed

this has been fixed in svn now. It was a backlgiht api change related bug that
happened in the transition to 2.6.21.

svn rev. 2115 has the fix.

Tested with 2118 here. Works.

Thanks!
