  I'm very sorry,before I posted it I didn't notice that

Alright! Now when actually reading/writing to the part, the 0x76 will be shifted 1 bit left ((0x76 << 1) | RW). But you probably already know that 

I opened my dingoo yesterday and I noticed a few other chips but I didn't actually look at them. I bet one of them has to do with audio and it is probably I2C controlled. But I didn't pay attention enough to notice what else would be on the bus - not that it matters very much for the TV Out, I would think.

If you are reading only 0xFF's, that means the reads are not done correctly - the device is not responding - you are simply reading the logic 1's produced by the pullup resistors...

I will do a little bit of digging and get back to you.

Thank you for your log; the reset sequence makes it work:

/ # i2cset -y i2c-gpio-1 0x76 0x03 0x00
/ # i2cset -y i2c-gpio-1 0x76 0x03 0x03
/ # i2cdump -y i2c-gpio-1 0x76

Any more progress or still under weather psycho? BTW if no one has said it I think we all appreciate your hard work on trying to figure this out for us...

I thought there were others working on it. Actually, I have to figure out why the dual boot loader won't work for me. I ran through the installation and when I press select and reset it, it just boots into the native OS.

Like I said, I can help but I don't know enough to work in linux. I could try to put together some tests in the native OS, but I am not sure it would do all that much good.

First of all thank you for your efforts on TV out.

Have you already gone through the installtion proccess of Dingux? If so you will just need to press SELECT while the Dingux splash screen shows up when you power on / resets the A320.

if it shows up the dinguxsplashscreen its your sdcard which isnt correct. Did you put the zimage first?

I am not sure how relevant this information is to the TV out, but is something I found out by accident.  When running dingux gmu (for listening to music via mp3's), I noticed that there was some odd background noise (if you hit play then pause there is a slight hiss in the background with occasional pops).  I thought this to be odd and had come to the conclusion that my power filter caps were probably starting to go (or were cheap).  BUT I accidentally plugged my headphones into the TV out and noticed the same thing.  I have not tested any theories on this, but I am wondering if the hissing/popping could be caused by the TV out functionality (ie if the tv out is getting a power signal sent to it just not processing the image properly)?
I am going to test this theory more soon (I have a few ideas on things).
