This repository contains the still evolving tool for the FOSDEM VIDEO hardware.

Current working setup:
----------------------

The TFP401 is pretty finicky about what modes it does accept correctly. We
need to provide some small hacks to have our test/validation setup work
correctly.

These issues should go away when we move to the ADV7611.

Output side:
------------

On the outputting allwinner device, run:

./test_output <frame_count> 74.5  1280 1390 1430 1652  720 725 730 752  +hsync +vsync

This is an adjusted modeline to make the tfp401 module happy.

Alternatively, run make in Documentation/EDID/ in the kernel tree, and copy
the 1280x720_tfp401.bin to /lib/firmware/edid/, and add the following to
u-boot commandline:
 drm.edid_firmware=edid/1280x720_tfp401.bin

That will automatically make the hdmi block select the right timing upon boot.

Another option is to write the edid rom to the TFP401 module, as described in
'readme.tfp401'.

Capture side:
-------------

On the capture device, run:

./juggler <frame_count> 216 22

This will set up the delays after h/vsync to make the tfp401 module provide a
correct image.

These settings have now been added as defaults in the CSI1 driver.
