To everyone else.

Thanks for your support :)

As apparently I'm just a chinese bootlegger or something, and Oraap really either doesn't read english properly (as _all_ his questions were answered in this thread) or he's just a :tool:

I've put my next set of findings back on my blog here:

http://www.computersolutions.cn/blog/2012/06/jz4755-jamma-board-reverse-engineering-part-3-king-of-game-board/
Those that are interested can go look there. Sigh..

For what its worth, I'm not a chinese bootlegger :)   I'm not even Chinese!
I have been posting on here for a number of years now, and bought the book many many moons ago too.

Even my first post on this thread about the GameBox stuff goes back to 2011, so its not like I suddenly jumped in here and was spamming sales stuff.
I've also been posting on this forum for a number of years now, its not like I suddenly popped up out of nowhere, and suddenly started posting..
Sigh.

If you look at the thread - people specifically asked for board prices.  Again, I don't make the board, I have zero to do with the board, except for buying a bunch off the factory for my own use.

Thats in reference to the future when /if I actually get the work done, can reflash boards, can make improvements, and sell that as a package, eg board+better rom. Its not an enticement to sell or buy anything yet, and its similar enough to a lot of other people doing similar stuff.  Classic example of this would be the NEO-GEO Universal Bios.   If I've overstepped a line talking about that kind of thing, then apologies, but I really don't think I have.

CheffoJeffo - comments?

I'm in China.  I can speak Chinese (again, I'm not Chinese).  This isn't even the business I'm in to be honest, we do Websites, and IT stuff, but I can organize things like that.  Again, its not a sales pitch, its a comment on whats doable.  If you really think I was spamming for sales, you're mistaken.

I don't think we all have to be robots, do we?   I like my style of writing, and others do too.  Informal, but informative is what people usually tell me.

I tried to be subtle about it, even ignored when you kept talking despite my bona fide warning. -- In any case, I believe you now. You convinced me.

Uh, junior, you are not in a position to warn anybody or dictate how or what they post.

Not my board, so not my call, but the rules are that you can't offer to sell anything here that you don't have a right to sell.

I like the technical talk and am interested to see where you can go with this.

I should be perfectly ok then, if / when at some undetermined point in the future I get a lot further along, finish, get my shiyat into gear   :blah:

Thanks.  Its quite a lot like like detective work, I enjoy making progress on stuff like this, plus I get to (l)earn "l33t" skills in reverse engineering and reading fun fun fun data sheets. I started out as an embedded systems guy in the early 90's in South Africa, but then moved to China to do IT, so this is hobbyist level stuff for me, to keep my skillset up to date :)

My last "self induced" project was similar work on IP Camera stuff - reverse engineering hardware, and seeing how it ticked.  I setup a community site for that myself after the posts on that took over my blog commentwise.  

I'll probably do that with this board at some point, but I guess another few posts won't hurt.

Back to the specs/future dreams   :lol  

The board is a dual core* @ 400mhz, underclocked to 336mhz on this.
*white lies.  It does have a CPU+GPU though, so technically its "dual core".
The video chipset has hardware rotation, and the chip has a frame buffer, so rotation looks doable.  Its MIPS vs ARM, but I think this kicks Raspberry PI's ass in terms of CPU, mostly as thats an ancient ARM5 core, and this has MMU etc..

What makes this interesting for me (and others I guess), is that unlike most other Chinese SoC's this one has actual documentation, and BSP's freely available.  Thats highly unusual.  Most of the time you need to beg, borrow or steal, er I mean acquire torrents / rapidshare rar's of said items.

I'm nowhere near anything practical yet.  Right now its a 2nd weekend working on it, but lots of good interesting progress.
Linux is going to be fairly easy to port as its 99% Gamebox GBX-0001 equivalent or 90% A380 Dingoo hardware, and the major work has already been done for that by others, so its mostly tweaks to get their stuff booting.  

We don't have SD though, and no screen or serial, so its going to be a case of make extremely sure I don't screwup, otherwise I'll be out a board if I go too far wrong...  

I'm not sure yet whether I go linux, or replace the emulator(s) used by the current MINIOS by rejigging the firmware, and sticking another better compiled one inside.  The latter looks like an easier route for now.  As to using Android on this,  64M ram is not really enough to run another emulation layer on top of an OS. Its never a good idea imho, unless you have oodles of CPU+RAM to spare.
 
In this case its MP4 player chipset hardware with fairly decent NAND size, ok RAM size, semi decent video for its class, so whatever the Dingoo or GameBox BGX001 does at the moment will be fairly similar speedwise.  Its the same thing as those 2 in a different form factor, but with JAMMA.

Definitely room for improvement on current speeds emulated though.
