Other Parts Discussed in Thread: OMAP-L137

Hello everybody ,

please I can see LIDD is available in HW , but can we use this way using std linux 3.2 driver we provide ?

I can see Raster mode only , am I wrong ?

thank you very much

Hi,

It doesn't seem like the da8xx-fb.c driver from the TI PSP supports LIDD mode at the moment.

Best regards,
Miroslav

Hi Miroslav ,

which is the easiest and fastest way to handle it ?

I see older OMAP-L137 driver has LIDD support .

Does it make sense to "import" this driver to actual am335x kernel or I am on the wrong path ?

do you see any other starting point or example to start not from scratch ?

any basic sw is very welcome

bye

Carlo

Hi Carlo,

Although we don't official support LIDD in our current 3.2 linux kernel below contains some links from someone in the Beaglebone community who got LIDD mode up and running.

The patches he used may not apply cleanly and may need a little bit of work but it should be a very good starting point.
