So, have you a working compiler now ? :confused:
Is it suitable for you? If not, just let me know,
because it's hard for me to create something really cool on C++ by myself
(hope it'd be fixed, as I'm learning the C++ course now)
but I can save your time by giving you the software you need. :rolleyes:

Sorry, you have to represent a company to order the demo :(

Check this post, download the archive,
follow the instruction and get two softwares
which possibly has the compiler included.

Unfortunately there is no ZSP compiler there, i think it is just a debugger...
I believe that the most important for RK2xxx DSP development is only the ZSP400 assembler, it's called "sdas".
No need to have a C compiler for that chip, its purpose is to write fast audio DSP algorithms.

If you can find that assembler, you'll be a hero !!! ;)

by the way, to sum it up :

RK26xx : 8051 core + ZSP400
RK27xx : ARM7E-J + ZSP400
RK28xx : ARM9E-J + ZSP400 (?)

I read somewhere that RK28xx had a ARM9. That would make sense.
This is a logical evolution so they can provide an MMU in order to support linux/android.

I am not surprised that the ZSP400 stays the common DSP core for their chips because they have all those audio/video decoders optimized for it.

There was a very old post...

"Benny:
Hi @all
After 2 Weeks of playing with the RKP-Game-Disassembler i had now
enough information to made my first RKP-Assembler (BETA-Version).
Includes a Documentation and a sample-program (Data-Viewer) and
some RKP-Game-Files. Actually it's all Assembler (LSI ZSP400 Instructions).
File-Upload.net - RKP-Disassembler_and_Assembler_v01.zip
Enjoy
Regards
Benny"

The link is still working.


P.S. Hot tip for searching via Google:
use "filetype:torrent", "filetype:rar", etc. before the words
to search for the pages with the links to those files

Thanks Wizard. I have seen this program yesterday.
AleMaxx and I were speaking about this and he gave me the link.
There is a sort of IDE which contains a very weird assembler.
It is true it seems like ZSP400 instructions, but I don't think it is too usable (try to compile some rk2xxx ZSP400 code and it won't work).

Of course it is always possible to use the datasheet of the ZSP400 and create our own assembler, like Benny did...
But that is a lot of effort in my opinion !!!! :(

Hey Knob and Sid. How the progress is going? Audio still unfixed? I ordered the same player as yours a few days ago and can't wait for postman :-)

Currently I am busy as hell and don't have time to do anything with SDK 27XX but I will definitely back to working on it.

But dont we already have a zsp400 compiler with firmware tools and the "rock compiler" that is under it, thats how we create the object code for rock .rkp apps or is this no good?
benny's assembler was made to create "rock" games only. firmware tools will create rk26xx firmware too.

I don't think we have it, but i would love to be wrong ! :)
We probably just need the ZSP400 assembler, its name is sdas.
I have never seen it anywhere.

Rk26xx is a 8051 core + ZSP400 core. The ZSP400 portion of the rk26xx (and rk27xx) code is already pre-compiled in the SDKs we have :(

I think Knob is right!

There is SDAS in rock compiler folder.

IF this is ZSP400 compiler then we can create stuff using ROCK TOOLS.
