PWM CTRL on QBliss Startintf

adituswerkstatt · Jul 5th 2011

Hello,

we got some difficulties enabling pwm ctrl on our QBlissA8-Starterkit.

After setting up the parameters in the boot-loader the display stays dark. On the console it always says "pwm support not supported". Does this mean, that it isnÂ´t possible to dim the display? It works fine with an atom-board installed on the starterkit.

WeÂ´re using these settings:
BPC - 255; BPF - 2000; BPD - 100, BPE - enabled

Many THX for your help!

Hello,
which kernel release do you use? The PWM feature should work since V1.04. Please refer "history.txt" under http://download.fs-net.de.

Thx for your reply.

I guess you mean the eboot release which is 1.04. The firmware of the QBliss itself report as v1.05.

Our configuration settings are ok though?

Hello,

i just forgot to set ContrastEnable in the display mode setting. Now it works really fine.

Thank you and sorry for the inconvenience.
