Mh. Better would be some linux code how to integrate the tvout into the graphic drivers. I think without, it's to hard to develop a linux tv-out driver.

The one how did the nativ OS implementation maybe has access to informations or code?

I'm doing the best I can trying to get what research I can as DD China isn't going to give me much on design or how they interact with the driver nor any source code.

I can't blame them as if they release the source it could be copied in other devices the same reason they don't release the OS source code.

If they did other companies would copy and mass produce it... SO in esscences for them it's a double edged sword to help or not to help when it comes to Dingux.

You need to make clear to them that TV-Out in Dingux will boost their sales a lot (i think).  ;D

Here?s an earlier thread on the subject: http://boards.dingoonity.org/dingux-general/request-for-dingux-program-to-change-tv-out/
There?s even an open source style hacking board with the same tv-out chip, and they have it working in Linux, but there is a problem:
Joyrider already tried both the armadeus approach and the kernel drivers, but there is a problem with I2C not seeing the device.

Oh Dingoolord, make it happen!  :D

I'm a little confused about Ingenic's Linux port for the jz47xx, what is the difference between booboo's linux
port and Ingenic's one?  And has anyone tryied running Ingeninc's Linux port in the dingoo?

It seems Ingenic's port currently supports a lot of features.  And finally, could someone please explain what is the
difference between the TFT/STN LCD Framebuffer driver and the Smart LCD Framebuffer driver?

I'm not sure on either and just got the information... I'm a wiz at searching and research but applying it in some cases such as this is a different thing all together. Just thought this might help with TV and other video related issues....

E-mailed Ingenics for access to their new Kernel and zImage files and source to there linux I posted above as we can't seem to access their FTP. Here is the message I wrote:

Dear Sir or Madame,

   We are working on a kernel for the Jz4740 processor called Dingux on the Dingoo-Digital A320.  We would love to have access to the latest version of your kernel and rootfs files so we can add these patches to our current version of the OS.

Every time we try to access your ftp we get a connection reset or denied access to the newest version of the files.

If you can?t give us access to the FTP could you please put them on File front or some file sharing location so we can download them.

This is two fold as some of the developers working on the Dingux are also working on the Ben Nanonote also. So any help you could provide would help a lot.

Thanks for your time and efforts and for building a wonderful processor.

Regards,

Justin B

PS: Below is a simplified Chinese translation of the same message I have written above? Here is the website we are trying to get the files from?.

http://www.ingenic.cn/pfWebplus/productServ/kfyd/linux/pfFixedPage.aspx


亲爱的主席先生或夫人,

我们正在努力为Jz4740处理器称为Dingux对Dingoo数字A320型内核。我们很愿意有机会为您的内核和rootfs最新版本的文件,因此我们可以添加到我们这些补丁的操作系统的最新版本。

每当我们试图访问您的FTP,我们得到一个连接重置或拒绝访问这些文件的最新版本。

如果你不能给我们访问FTP可以请你把文件前面或一些文件共享位置,以便我们可以下载它们。

这是两个关于一些开发工作的Dingux倍,也可在本Nanonote积极开展工作。所以,你可以提供任何帮助将有很大的帮助。

感谢您的时间和努力,为建设一个美好的处理器。

的问候,

贾斯汀巴里克

sigh there's no need for that there are (svn) mirror's on qihardware from the development tree's

From what I could see of the mirror it's not got the latest version that was put out a couple days ago JoyRider I sent you a PM you never responded to it.

I think someone has to go into this. I don't think that the different sources or links help us. The interface and lcd of the dingoo is different.

I compiled the kernel with i2c support and executed i2cdetect. That is what i found out so far.

Code: [Select]
/ # i2cdetect -l
i2c-0   i2c             jz_i2c-i2c.0                            I2C adapter

/ # i2cdetect jz_i2c-i2c.0
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-0.
I will probe address range 0x03-0x77.
Continue? [Y/n]
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f
10: 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f
20: 20 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f
30: -- -- -- -- -- -- -- -- 38 39 3a 3b 3c 3d 3e 3f
40: 40 41 42 43 44 45 46 47 48 49 4a 4b 4c 4d 4e 4f

70: 70 71 72 73 74 75 76 77

/ # i2cdetect -F jz_i2c-i2c.0
Functionalities implemented by /dev/i2c-0:
I2C                              yes
SMBus Quick Command              yes
SMBus Send Byte                  yes
SMBus Receive Byte               yes
SMBus Write Byte                 yes
SMBus Read Byte                  yes
SMBus Write Word                 yes
SMBus Read Word                  yes
SMBus Process Call               yes
SMBus Block Write                yes
SMBus Block Read                 no
SMBus Block Process Call         no
SMBus PEC                        yes
I2C Block Write                  yes
I2C Block Read                   yes

I also compiled and executed "ch7024ctrl" of the ArmadeuS project. But this tool can initialize the i2c but can't find the ch7024 on the dingoo.

every i2c device has an address, some are changeable, other aren't, in order to acess a device you have to send the device address, then do other things depending on what you want to do.  could be it's trying the wrong adress, it might've been changed for the dingoo or whatever

(no i can't help seriously, bit busy doing i2c stuff at uni to find the time  ;D)

Yes i know. But whats the adress?

In document "7024ds.pdf" it says.

Device ID - 00h

Also in the "ch7024ctrl" source it's 00h.

So whats the ID on the Dingoo ;) ?
