- display stays black. Any ideas?

<pre wrap="">Hm. This can be a lot of things. Maybe X11 config.
Do you see a /sys/class/backlight entry?
</pre>
</blockquote>
<pre wrap="">No x11. This is a minimal cli-only system.
/sys/class/backlight is as empty as can be.
I found that there are only 2 display connector modules available:
connector-analog-tv.ko, connector-hdmi.ko
With only the former loaded.

<pre wrap="">That is ok since the omap3 has no hdmi port.
The panel is a separate driver.

<blockquote type="cite">
<pre wrap="">menuconfig lists DPI, HDMI, SDI and DSI.
Is this the key here?
And we are probably also missing the panel drivers.
</pre>
</blockquote>
<pre wrap="">Hm. The display system should work upstream - but maybe
they are not configured?
Display backlight also needs some omap pwm driver so this
can be the reason why it does not show up in /sys/class/backlight.

we have backlight/pwm related:

<pre wrap="">Do you know if this one is necessary? Its description is quote short.
Just in case Debian maintainers want to know an expalantions for every
option I request enabling.

<blockquote type="cite">
<pre wrap="">CONFIG_BACKLIGHT_PWM=m
CONFIG_PWM=y
CONFIG_PWM_SYSFS=y
CONFIG_PWM_OMAP_DMTIMER=m
And for panel:
CONFIG_DRM_OMAP_PANEL_TPO_TD028TTEC1=m

<pre wrap="">From those, missing are:
BACKLIGHT_GENERIC
DRM_OMAP_PANEL_TPO_TD028TTEC1
PWM_OMAP_DMTIMER
I am enabling them, and rebuilding this huge allmodconfig to test later.</pre>

I found that replicant has<br>
CONFIG_FB_OMAP2_PANEL_TPO_TD028TTEC1<br>
But you don't. So I will try without it first.<br>
