Hi, Thomas:
Your "config-arm" says the drm driver was built as a kernel module.
So did you try to run "modprobe tegra-drm" after system booted?
Or, I suggest you can change the drm driver to be built into kernel
while not be built as a module. In Thierry's kernel config, drm driver
is built as a module, this is good for debugging but may not be
convenient for users.
In addition, are you sure you have enabled the backlight?

Hi,
I'm trying to run Thierry's latest linux kernel
(git://gitorious.org/thierryreding/linux.git branch: tegra/next commit:
1633170) which contains the Tegra DRM driver on my AC100, but without
success.
I did these steps:
1.) Patch kernel with attached patches. One patch is to support the
native AC100 partition scheme, the other one is for the device tree.
2.) Compile the kernel with the attached boot config.
3.) attach the compiled device-tree file to the zImage via "cat zImage
tegra20-paz00 > zImage".
4.) Use abootimg to create an android boot loader file
After a reboot all I get is a blank screen, no messages, no errors,
nothing. Sadly this device has no serial port, so any help is
appreciated!
What am I missing/doing wrong?
with kind regards
thomas
