Objet : [directfb-dev] iMX31 - Freescale
Hello All,
a couple neat things.
I need to develop or obtain an accelerated driver for the iMX31 from freescale.
I am using a SOM from LogicPD
DirectFB runs Dog slow, the OpenGL driver from PowerVR is broken.
I have yet to determine where the breakage is, IPU, PMIC, or any bus problems
along the way. (if its not the driver itself)
Our company is ready to contract someone to develop this, I want to develop it
but I cannot seem to get my plate clean enough to take it on.
so:
1.) Does anyone have this configuration and is willing to partake in the
adventure?
(LogicPD iMX 31 development kit with LCD will work nicely)
2.) Does anyone have any offerings on an accelerated iMX driver
3.) Has the MBX chip received any love from DFB prior to this?
if none of this then:
1.) Is there a DFB consultant I can use to accelerate my development of this
driver?
and what can you do for me if we contract your services?
I look forward to hearing any responses to this.
I appreciate your time and hope this is not the wrong place to ask these types
of questions.
In the meantime, I will be cleaning my plate getting geared up to do this
myself.
-Chris

Hi Chris,
I'm using Dfb for a simple LCD/Keypad front-panel interface on our
Logicpd/SOM-based imx31 design .
Here's my feedback on IPU/Framebuffer/Directfb1.0.0, so far : my display is an
asynchronous (smart) HX8340-based 176*220 display from URT. I had to adapt a
ADC/FB driver for it; once you have the good channel template for the IPU and
the init sequence for the LCD's controler, your pretty much done with the ADC
driver part. I don't need any 3D nore video, so I could stick to the basic
graphic primitives (no SDL, no WM), and so far Dfb suits my needs : I don't get
glitches in my audio or network activity when I operate the front-panel menus.
I made an attempt to put a hardware rotation channel into action, but it still
needs some debugging, and as I couldn't get great support from Freescale on the
IPU API, I went rotating the text only, in software for now, thanks to the
patches from Phil and Denis.
I'm intersted into what I can achieve on hw acceleration, so if you need
someone with a similar platform to do some testing, maybe I can help, but I
probably won't have much time to help developing or debugging until end of
november or so.
best regards,
Marc
